Efficient with various liquids

A progressive cavity pump...

...is a positive displacement pump that is able to convey liquids gently and at a constant flow rate. It is particularly suitable for viscous, abrasive or sensitive media and is used in a variety of applications in slurry and biogas technology as well as in industrial applications and waste water treatment. The features of the progressive cavity pump are the block design with bearing bracket, suction housing, rotor and stator. The main advantage of this pump is its high flow rate and the fact that it is easy to repair. The universally applicable pump is suitable for conveying almost all low to high viscosity media.

Technical data

Wide viscosity range
Consistent modular principle allows high flexibility, low spare parts inventory and short downtimes for repair work
Optional with base plate
Excellent price/performance ratio
Almost pulsation-free conveying
Optimum service life even with difficult media
High suction power (self-priming under certain conditions)
Joint connections of constant diameter for constant flow velocities
Easy to maintain due to large cleaning openings
High operational reliability
Good delivery performance even with high back pressure and abrasive and fibrous additives in media

Immersion pump type EXT

The EXT progressing cavity pump is suitable as an immersion pump for pumping media from tanks, pre-pits and mixing tanks. The pumped media are pumped reliably and gently with a high dry matter content. The fugator fitted as standard prevents clogging in the suction area and guarantees reliable pump operation.

Advantages and features of the submersible pump

Modular design
Wide viscosity range
Constant diameter joint connections for constant flow rates
Dosing accuracy even at low speeds
Low space requirement thanks to vertical design
High operational reliability
Configuration and length according to customer requirements
Consistent modular principle facilitates spare parts handling
Low-pulsation, continuous delivery independent of pressure and viscosity
Easy to maintain
