    Design

    • Single-stage, end-suction centrifugal volute pumps.
    • Main dimensions, compatible with EN 733 (DIN 24255) norm. A total of 45 designed pumps avaible 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 standart 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.
    • Use of extended coupling also enables the removal of the pump fixtureswithout 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 of only 6 bearings and 10 shaft types, thus simplifying spare parts procurement.
