Knowledge and Technology

Selecting the right eccentric screw pump depends on the viscosity of the fluid, the required discharge pressure, and the application. The following sections explain the operating principle, the modular design, and a comparison of the different series.

Function and Design of Eccentric Screw Pumps

VISCOPOWER eccentric screw pumps are a type of rotary positive displacement pump. An eccentric screw (rotor) rotates in an oscillating motion against a stationary stator. The screw-shaped geometry creates enclosed pumping chambers that continuously displace the fluid from the pump inlet to the outlet.

The flow rate is proportional to the rotational speed—regardless of the medium’s viscosity and consistency. A variable-frequency drive allows for precise control of the flow rate. 

Design

  1. Motor flange or gearbox: Motor flange for mounting three-phase motors or a gearbox for commutator motors and brushless motors.
  2. Motor connection: For motor flange or gearbox. Easily convertible and compatible with all motor types.
  3. Clamp connection: Secure connection that won’t loosen due to vibrations. Advantage over a union nut.
  4. Mechanical seal: Sealed design for hygienic applications or open design for industrial applications.
  5. Torsion shaft: Reinforced shaft for higher torque transmission.
  6. Electropolished stainless steel pump tube: Robust pump tube available in five standard lengths: 400, 700, 1,000, 1,200, and 1,500 mm.
  7. O-ring seal: Seals the gap between the rotor and the drive shaft. The exposed design allows for easy and hygienic cleaning.
  8. Rotor: Four different rotor-stator geometries for various pumping applications.
  9. Stator: Available in PTFE, NBR, and FKM. Suitable for various media requirements.
  10. Stator housing: With integrated, reinforced suction protection. Also available in a version for drums with liners.

Modular System

The modular system allows for the free combination of pump tubing, rotor geometry, stator material, motor connection, and immersion depth—for both industrial and hygienic applications.

  • Versatile: Industry, hygiene, and hazardous areas—depending on the model
  • Flexible range of applications: Mobile and stationary, vertical and horizontal, as a submersible pump or dry-mounted
  • Safe Handling: Few components, quick to disassemble, intuitive cleaning

Bayonet lock for easy motor connection

Thanks to the bayonet connection on the motor flange variant, the pump can be easily hooked onto the motor and the screws can then be tightened without having to hold the pump in place.

How does an eccentric screw pump work?
 

The fluid to be pumped is fed into a pumping chamber and displaced upward by the rotating eccentric screw. The helical geometry of the rotor and stator creates sealed pumping chambers that move continuously from the inlet to the outlet.

The result: uniform, pulsation-free delivery at constant pressure. In FLUX pumps, the eccentric screws are made of stainless steel, and the stators are made of NBR, FKM, PTFE, or EPDM.

Disassembles in 30 seconds for cleaning

VISCOPOWER can be disassembled in about 30 seconds without tools. Ideal for applications involving frequent product changes and high hygiene requirements.

The maximum flow rate is a test bench value, measured with water at 20 °C at the pump’s discharge port, without any attachments (hose, dispensing nozzle, flow meter). The flow rate that can be achieved in practice is lower and depends on the specific application, the properties of the fluid, and the pump configuration. Specifications are for an axial rotor, unless otherwise noted.
