11 Features.9. Copact Design The copact design allows for easy installtion even in confined spaces. Robust The echanical structure of the hydraulic parts in contact with the puped liquid are diensioned to guarantee the axiu resistence to echanical stress. unique design The lantern bracket design prevents contact with the pups rotating parts, providing protection to the end user whilst allowing for inspection of the echanical seal. Reliable The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability under all operating conditions. 7

12 D Features.9. Flexible The option to choose between cast iron and bronze aterias for the hydraulic parts in contact with the puped liquid allows D series pups to be selected for use with different types of liquids. Robust The echanical structure of the hydraulic parts in contact with the puped liquid are diensioned to guarantee the axiu resistence to echanical stress. Reliable The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability under all operating conditions.
