eccentric screw Pumps for almost all applications

In addition to our barrel pumps for low viscosity and medium viscosity media up to 1000 mPas, we can offer a complete range of high viscosity eccentric screw pumps for transporting highly viscous, still flowable media. Our large stock pumps are of the type of eccentric screw pumps, where the flow rate is determined by the geometry and the clearance between the rotating rotor (screw conveyor of stainless steel) and the stationary stator (in the opposite direction rubber or solid mixture).

For almost 10 years, we supply our pumps to customers in industry and agriculture.

We also repair other brands reliably.

We can offer you our high viscosity dosing pumps in different versions:

In principle, the first step is to choose between the vertical or horizontal version of a drum or container pump.

Eccentric screw pumps as drum and container pumps

With electric motor or air operated motor, they are used to transport thin liquids and viscous substances to 100,000 mPas, preferably stationary, used in continuous operation.

The flow rates are standard at 12, 25 or 50 liters/min, the funding pressures on 6 or 12 bar. We can also build the vertical design as a dosing pump with a small performance.

The pump tubes are made of stainless steel 316Ti, the stators of NBR, NBR light, FKM, EPDM, EPDM light or PTFE.

Eccentric screw pumps as container pumps

With AC motor, three-phase motor or air operated motor, they are used to transport thin liquids and viscous substances to 100,000 mPas, preferably stationary, used in continuous operation (also ATEX certified).

The flow rates are standard at 80, 200 or 300 liters/min, the funding pressures on 6 or 12 bar. 

The pump tubes are made of stainless steel 316Ti, the stators of NBR, NBR light, FKM, EPDM, EPDM light or PTFE.

Horizontal eccentric screw pumps

Transport liquids with low or high viscosity, neutral or aggressive, with or without solids or fibers.

The pump tubes are made of stainless steel 316Ti,
the stators of NBR, NBR light, FKM, EPDM, EPDM light or PTFE.

Flow rate: up to 3 m³/h, pressure stages: 6 and 12 bar

Horizontal pumps in block version

A cost-effective variant are the pumps in block version. At these pumps the motor is directly flanged. By saving the bearing base as well as the elastic coupling, shorter designs can be realized.

Flow rate: up to 200 m³/h, pressure stages: 6 and 12 bar

high viscosity dosing pumps

Suitable for dispensing low viscosity, viscous, neutral and aggressive media with or without solids.

The standard flown rate of this series are between 0.6 – 60 l/h.

The flow rate is either controlled by a hand-shifted motor or a geared motor with frequency converters.

Also a series as a drum pump, as well as filling systems for the dosing of small quantities are available.

drum emptying stations

Mobile and stationary drum emptying stations.

Stationary drum emptying stations with follower plate for non-flowable media.

Bottling plant with hopper.

 

spare parts

Spare parts for eccentric screw pumps: stators, rotors, pump parts, couplers, mechanical seals, cuffs, etc.

If you have regular spare parts requirements, we also offer you a free storage of the spare parts for our eccentric screw pumps.

We also perform pump repairs and maintenance in our company quickly and reliably. Our quotations are free of charge.

In addition, our technicians offer you competent and free of charge consultations to extend the life of your eccentric screw pumps. Beside the exact application, we also check the suitability of the selected pump materials.
