25 Reading curves and selecting a pump DOMESTIC HOT WATER PUMPS - AP, AKP and AEP Selecting a fixed speed pump from Hz pump curve (the curves on the left) E.g. duty point: flow =.9 l/s, head =. m, liquid: water + C.. Use the quick selection chart at the beginning of the catalogue or check the datasheets in the product catalogue in order and search for a pump with the correct size range such that the required flow.9 l/s is at the best efficiency point.. Select the impeller size [Ø= mm] from the QH curve such that a vertical line is drawn at the point of.9 l/s flow through all curves and, equivalently, a horizontal line at the point of.m head.. At the intersection, find the impeller size = mm. Note! If the intersection falls between two impeller sizes, the impeller size is selected halfway between the two sizes.. The nominal shaft power of the motor is read from the section where the QH curve and the duty point are. In this example, the motor nominal shaft power is PN =. kw. According to the shaft power P, P =. kw -> the motor nominal power becomes PN =. kw (the closest highest motor nominal power).,kw,kw AEP-/ AEP-/ Hz Hz Motor V OP-7 B N OP-7 N Motor -V(-V) OP-7 B N OP-7 N P N [kw] I N [A] [kg] H [mm],, 9, 7,,, 7 P N [kw] I N [A] [kg] H [mm], (,), (,) 9, 7, (,9), (,), 7 Hz r/min G Hz r/min G NPS NPS m/s m/s m/s m/s m/s m/s 7 7 Ø Ø,,,,,,,,,,,,,,,,,, Q [m /h] Q [m /h] P [kw] P [kw],, Ø Ø,, Ø7 Ø7,,,,,,,,,,,,,,,,,,,, P,, [kw] Ø Ø,,,, Ø7 Ø7,,,,,,,,,,,,,,,,,,,,, Ø Ø Ø7 Ø7,,,,,,,,,,,,,,,,,,.

Use the quick selection chart at the beginning of the catalogue or browse through the product catalogue in order to find a pump of the correct size range such that the required flow l/s is at the best efficiency point (ɳ = %).. Select the impeller size [Ø= mm] from the QH curve such that a vertical line is drawn at the point of l/s flow through all curves and, equivalently, a horizontal line at the point of m head.. Find the impeller size at the intersection= mm. Note! If the intersection falls between two impeller sizes, the impeller diameter is selected halfway between the two sizes.. Read the nominal shaft power of the motor from the section in which the QH curve is. In this example, the motor nominal shaft power is PN = 7 kw. According to the shaft power P, P = 7 kw, the motor nominal power becomes PN = 7 kw (the closest highest motor nominal power).

For energy calculation, read the electrical power of the device = P [kw], from the P curve with a required flow of Q = l/s and at the point of the selected impeller size, Ø = mm. In this example, the device electrical power is P= 7 kw.. Energy costs = Electrical power P [kw] x energy price [ / kwh] x operating time [h]. Characteristic curves apply to + C water. Note! Please contact Kolmeks for additional information on the following issues!. When pumping liquids whose viscosity differs from that of water, the effect of viscosity must be considered in pump selection.. Liquid density is directly proportional to the power requirement. The sufficiency of motor power must be checked for liquids denser than water. 7 / Subject to change without prior notice.

E.g. duty point: flow = l/s, head = m, pumped liquid being water + C.. Use the quick selection chart at the beginning of the catalogue or check the datasheets in the product catalogue to find a pump in the correct size range such that the required flow is in the best efficiency point. The AL-/ pump is selected because its efficiency is the best in the required duty point ɳ = 7%.. The duty point is outside the operating range of the AL-/ Hz pump.. Usually when selecting the pump from the Hz curve to the required duty point (Q = l/s, m), the next largest pump is selected. In the above example, we choose AL-/, Ømm, PN = kw, ɳ = 7%. This is an oversized pump whose best flow range is within l/s, where its efficiency is the highest ɳ = %.. Select the pump AL-/ from the Hz curve, whereby the impeller is Ø7mm.The nominal motor shaft power PN is selected according to the shaft power curve P. Shaft power P = kw and the next higher nominal power is PN = kw. In this example, we choose AL-/, Ø7mm, PN = kw, ɳ = 7%. Q [m /h] QH curves are available for Hz and Hz on the same datasheet in order to facilitate the customer s selection of the most energy efficient pump for frequency converter operation. How does careful pump selection benefit the customer?. The pump saves energy, because it has been selected from the range of the best efficiency.. The total purchase cost is lower, because the pump, the electric motor and the frequency converter are one size smaller.. The pumps are designed to operate at the best efficiency where they run with low noise and vibration and have a long service life.. A smaller pump saves energy in partial flows, because its efficiency is better for the entire operating range. / Subject to change without prior notice. 77

The re value required of the pump must be smaller than the av value in order to prevent cavitation from occurring. A safety margin of. m must be added to the measurement value. av = difference between available inlet pressure (in suction flange) and vapour pressure of liquid being pumped re = value required by the pump p = Absolute air pressure p h = Absolute liquid vapour pressure at the operating temperature h = Liquid geodetic suction head h suction = Pressure losses in suction pipes p suction = Absolute suction pressure p h [m] Vapour pressure (water) T[ o C] At normal air pressure levels ( m water column,, mbar = 7 mm Hg), clean water boils at C. It can be seen from the curve that water boils at C when the absolute pressure is m wc (i.e. m wc below atmospheric pressure). The boiling point of water at less than C can be achieved at a very low pressure. Vice versa, at the top of Mount Everest, where air pressure is about. bar ( m), water boils at + C.

136 TWIN PUMPS - T and AT General technical data T and AT series twin pumps: Vertically installed inline centrifugal pumps Applications T and AT series pumps can be used as in circulating, pressure boosting and transfer pump systems for clean liquids in applications which require operational reliability and adjustable pumping. Structure Pump T and AT series twin pumps are vertically installed monoblock-constructed centrifugal pumps equipped with a dry motor. The pump impellers are installed directly onto the shaft of the electric motor (no separate couplings). Both units of the twin pump rotate in the same direction (except AT-, -, -9, - and -). The twin pumps include a pump housing with two pump hydraulics which is cast as one piece and is additionally equipped with an automatic relief valve to prevent internal circulation. The relief valve does not operate as a non-return valve required by the system. The change over duty of the pump units can easily be automatised, because there is no need to open or close the valves in the piping when changing the operating unit.

As one runs, the other operates as an automatic standby unit which starts automatically if the running pump stops e.g. if a thermal relay has tripped. We recommend adding alternate operation to this, allowing for both units to evenly obtain operating hours. This better ensures that they remain in good technical condition. A suitable alternation interval can be achieved e.g. by using a weekly clock. / Subject to change without prior notice.

142 TWIN PUMPS - T and AT b) Controlling twin pump according to pumping need The units of the twin pump are different from each other. The unit of larger flow only runs when there is high demand; otherwise the smaller unit is in use. This arrangement achieves considerable savings in operation costs. Furthermore, the noises in circulating system with the large pump can be avoided when the demand for pumping is low. Most often in these cases, the other unit operates as an adequate automatic standby pump. Control information can be obtained as needed e.g. from temperature, pressure, differential pressure, clock etc. T-B//Ø, kw T-B//Ø, kw c) Combined operation of twin pump with large flow The twin pump can also be used such that large flow is pumped by both units in parallel: but when demand is low, only one unit operates. In this case, the units must be similar. When using the pump in this way, the duty points on the pump QH curves and system curves should be very accurately determined. In circulation systems especially, it is often possible that no increase in pumping is obtained even with the parallel use of two similar pumps. This use can be applicable in situations where the system includes static head. For example, when transferring liquid from one tank to another from a lower level to an upper level. We also recommend alternation running in this case, whereby the devices are better maintained in good technical condition. T-B//Ø. kw, two units running T-B//Ø. kw, only one unit running d) Frequency converter integrated alternation automation The pump alternation automation can be integrated with frequency converter operation, whereby the frequency converter pump can be alternated as usual. In most fault situations, the other pump automatically switches on to the fixed speed (bypassing the frequency converter). / Subject to change without prior notice.

143 TWIN PUMPS - T and AT Installation Small pumps (<DN, less than. kw motors) can be installed in the piping without support. Ensure the following when installing the pump: - Enough room for service and inspection - Possibility to use lifting and transfer devices if required - Check valves on both sides of the pump. The position of the motor unit and therefore the location of the terminal box can be changed by detaching the motor unit from the pump housing and by installing it in the required position. Large pumps are fastened by their foot to a freely moving concrete base which is insulated from the floor e.g. by a mm thick rubber or cork mat. The weight of the concrete base must be about. times the weight of the pump.

145 TWIN PUMPS - T and AT Reading of twin pump curves and pump selection Please see below the datasheet for a twin pump which includes four different QH curves of the same pump, allowing for the selection of a pump in four different ways: Pump selection and operation in the circulating system:. One unit in operation Hz: QH curve (.) on the left -> one unit runs with the maximum frequency Hz. Fixed-speed operation and Hz supply where one unit gives the required flow and the other operates as a % stand-by unit. The rotation speed can be controlled using a frequency converter from Hz and downwards.. Two units in parallel operation Hz: QH curve (.) -second from the left -> when both units run in parallel at the maximum frequency of Hz, whereby the required flow is achieved. When only one unit runs, about 7% of the required flow is achieved. In fixed-speed operation and with a Hz power supply, the rotation speed of the pump can be controlled using the frequency converter from Hz and downwards, whereby the required flow is achieved with both units running in parallel at the maximum speed. During low flow, only one unit runs. In order for both to obtain the same operating hours, the units must alternate e.g. at an interval of days.. One unit operation Hz: QH curve (.) third from the left -> one unit runs at the maximum frequency of Hz (frequency converter operation or Hz power supplies). One unit achieves the required flow and the other operates as a % standby unit. The rotation speed of the pump can be controlled using the frequency converter from Hz and downwards.. Two units in parallel operation Hz: QH curve (.) on the right -> the required flow is achieved when both units run in parallel with the maximum frequency of Hz. About 7% of the required flow is achieved when only one unit runs.

The motor is selected from between power limit lines where the QH curve of the selected impeller and the required flow are. In this case, the nominal motor shaft power PN = kw. The motor can also be selected according to shaft power P in the duty point. By drawing a horizontal line from the intersection of the selected impeller and the vertical line to the P curves, it is possible to read the duty point shaft power P = 9.9 kw. In this case, PN = kw is selected as the nominal power of the motor (the closest higher motor nominal power).. The nominal current of the electric motor is read from the IN column of the table -> IN =.7 A, and power supply components (short-circuit protection, switch, cable, overload protection, etc.) are selected based on this value.. The pump weight is read from the [kg] column of the table -> 9 kg. 7. To calculate energy costs, a horizontal line is drawn to the P curves from the intersection of the selected impeller and the vertical line. The input power of the device according to the reference point P =.9 kw (motor electrical power) is read from the vertical axis.. Energy costs [ ] = Electrical power P [kw] x energy price [ / kwh] x operating time [h].. The correct pump is selected from the quick selection chart (at the beginning of the catalogue) and datasheets such that the required flow l/s is in the best efficiency point of the pump curve. The selected pump is AT-9/ (pump efficiency ɳ = 7%).. The impeller size [Ø= mm], is selected from the QH curves such that a vertical line is drawn at the point of l/s flow through all curves and, equivalently, a horizontal line through the QH curves at the point of m head.. The impeller size is selected at the intersection of the lines (duty point) -> 7 mm. If the intersection is in between two impeller sizes, the average of the two sizes is selected as the impeller size. Characteristic curves apply to + C water. Note! When pumping liquids which differ from water with regard to their viscosity, density and temperature, please consider their effect on the motor shaft power and the impeller diameter when dimensioning the pump (e.g. indirect refrigeration systems).

223 ATEX PUMPS - AE, L and T Installation and commissioning Please ensure the following when installing a pump: - allow enough room for service and inspection - possibility to use lifting and transfer devices if required - shut-off valves on both sides of the pump Small pumps (less than kw) can be installed in the piping without support. Large pumps are fastened by their foot onto a freely moving concrete plinth floated on e.g. a -mm thick rubber or cork mat The weight of the concrete plinth must be about. times the weight of the pump. The position of the motor unit and the location of the electrical connection box can be changed by detaching the motor unit from the pump housing and then rotating it to the desired position (does not apply to the LH series). Electrical connections need to be carried out by a qualified electrician and approved by local authorities. Check that the motor connections correspond to the local supply voltage. Standard/factory connections: NOTE! The motor must always be protected by an overload protection switch which is set at its maximum to a nominal current equivalent to the connection in question. The motors of the twin pump must be connected individually to different supply cables, main switches and fuses/mcb s The rotational direction of the pump must be checked when starting-up and always after a new connection. The correct direction of rotation is marked with an arrow in the pump housing. Before start-up, the system must be filled with liquid and vented. Free rotation of the pump can be ensured by rotating the pump by hand e.g. from the motor fan. NOTE! The pump should not be started or used if it has not been filled with liquid and vented. 7 After start-up, please check that there are no extra noises coming from the pump and that no leakages appear. NOTE! The pump cannot be used with a frequency converter. Run both units of the twin pump alternately. A suitable alternating period is about two weeks. Do not prevent the motor from accessing cooling air. Keep the surfaces of the pump and the motor clean in order to guarantee cooling. Regularly remove dust which gathers on the surfaces. / Subject to change without prior notice.

First, the correct size of the pump is estimated so that the required flow [l/s] is in the best efficiency point of the pump.. Then, the impeller is selected from the QH curve according to the following: at the point of flow [l/s], a vertical line is drawn and, equivalently at the point of head [m], a horizontal line is drawn. The impeller diameter is estimated at the point where these lines intersect.. If the intersection falls between two impeller sizes, it is possible to select a so-called fractional-size impeller. In such cases, the impeller diameter is determined from the middle of these two impellers.. At the same time, the nominal shaft powern of the motor is read based on the motor power range into which the QH curve falls..next, based on the nominal shaft power of the motor, the nominal current value of the electric motor is read. According to this reading, an electrician will adjust the motor overload protection.. From the same table, it is also possible to read the pump weight. It is possible to determine the nominal shaft power Pn of the electric motor according to the shaft power curve (P) of the pump. 7. It is possible to read the input electric power [kw] of the pump from the input power curve (P) of the device. Each flow [l/s] in question is selected from the point of the impeller diameter, from which it is possible to calculate the actual energy consumption of the pump. Then, the value in question is multiplied by annual energy price [ /kwh] and operating time [h]: e.g. P [kw] x X [ /kwh] x,7 h. Performance curves are valid to Hz frequency and + C water. 7 Please contact Kolmeks for additional information on the following issues! ) When pumping liquids which differ from water in their viscosity and/or density, the effect of viscosity and density needs to be considered when selecting a pump. ) The density of the liquid is directly proportional to the power requirement. The sufficiency of motor power must be checked when pumping liquid denser than water. / Subject to change without prior notice.

Can be applied inside the pump housing and to the internal surfaces of the sealing flange. Urethane insulation of sealing flange Used in refrigeration systems when the temperature is below C. Can only be applied to the outer surfaces of the sealing flange. Non-standard flanges If required, the pumps can be delivered with ANSI, NP and PN borings. PN flanges are standard. (DN- flanges are the same PN and PN.) Pumping without a foot valve when the liquid level is below the pump The pump is equipped with an automatic aspirator which fills the suction pipe before the pump starts, making pumping possible without a foot valve. After the pumping has stopped, the suction pipe empties. As pumping starts again, the aspirator fills the suction pipe before the pump starts. An advantage is smaller energy consumption, because there is no suction loss caused by the foot valve. As the suction pipe empties after the pumping has stopped, there is no risk of freezing in winter. The aspirator can therefore be used in various outdoor applications. The device is commonly used in water supply plants, decking washing water pumps, bilge pumps and various industrial applications. The device requires compressed air to operate. Several sizes are available. The device size is dependent on the pumping capacity of the system. The device is delivered separately with the pump and the delivery includes all connections and pipes required for installation. / Subject to change without prior notice. 9

244 PUMP SERVICE General notes Kolmeks pumps do not require regular service. The pump shaft seal is a mechanical seal (not used in wet motor pumps). It is a part which undergoes wear and which must be replaced if it starts to leak. Please note that a leakage of a few drops per hour can be quite normal, especially when pumping water-glycol mixtures. The pump motor bearings are pre-lubricated and can thus withstand several years of continuous use. In case of any motor malfunction, we recommend replacing the whole motor unit. Motor unit replacement The pump motor unit includes: motor, sealing flange, impeller and seals. If a motor malfunction or a seal leak occurs, replacing the motor unit is simple and quick and does not require long periods of stand-by or operation downtime. There is no need to carry out procedures on the piping, because there is no need to detach the pump housing.
