Electric Chemical bellows pumps JP-900
Chemical bellows pumps - made of Polypropylene and PVDF for pumping aggressive media such as acids and alkalies
Our new chemical bellows pumps are based on the principle of a positive displacement or rotary lobe pump. Due to their simple design and numerous possibilities, these pumps are the optimal solution for your aggressive and demanding pumping tasks.
The fluid is pushed by the eccentrically rotating piston (rotor) inside the pump housing, from the suction port towards the discharge port. The flow direction of the pump corresponds to the rotation direction of the motor. In both flow directions the pumps deliver their full pumping capacity.

JP-900.70, nominal capacity 70 l/min.
Operating principle
An elastic rubber component (the so-called pump bellows) completely covers the rotor and is available in various materials: FKM, EPDM, Buna (NBR) for oils. The pump bellows is simultaneously pressed tightly against the housing by the flange and end plate. As a result, the rotor and internal components of the pump are completely separated from the conveyed medium. Therefore, the fluid being pumped only gets in contact with the inner surface of the housing and the outer surface of the elastic pump bellows, with the latter being the only component subject to natural wear.
The pump flange and end plate are made from durable cast steel and are specially coated. Due to the closed design, the shaft and bearings are well protected against aggressive external influences.
