DOSING – PISTON PUMPS

Pump with higher performance for continuous operation
Applications:

– Industrial processes

■ Stroke length: 15 mm
■ Stroke length adjustment range: 0 – 100 %
■ Stroke adjustment: manual with self-locking turntable in steps of 0.2 % (optionally with
electric actuator or steering drive)
■ Measurement reproducibility is better than ± 1 % within the 10-100 % stroke volume adjustment range
under certain defined conditions and with correct installation
■ Wet materials: Stainless steel 1.4571/1.4404, special materials are available on request
■ High performance oxide ceramic piston
■ A wide range of powerful versions are available: Three-phase standard motor, 1-phase AC motor,
motors for use in areas subject to explosion and different flange designs for use in customer specific
engines
■ Degree of protection IP 55
■ Very rigid fiberglass reinforced plastic housing with excellent chemical resistance
■ Provide suitable overload protection in all piston dosing pumps during installation for safety reasons
