Main dimensions, compatible with EN 733 (DIN 24255) norm. A total of 48 designed pumps available in the series. Single suction with closed impeller, and thrust balanced by means of counter-balancing holes and back wear rings, thus acquiring a dynamic balance. The pump and the motor have a standard connection to the common base plate with a flexible coupling. Maintenance and repair procedures are easily carried out since the pump fixtures can be removed with the volute body remaining intact. Use of extended coupling also enables the removal of the pump fixtures without moving the motor or the volute body. The series has been designed so that parts are easily replaced and standardized. The entire series is made up of only 6 bearings and 10 shaft types, thus simplifying spare parts procurement.
