Product information "Eccentric screw pump tube B70V-D Industry"

Flow rate: 25 l/min .
Drive shaft: Cardan shaft (GW)
Seal type: Stuffing box 
Note: Optionally, the stator size 25.2 and the nominal dimension 1100 mm (0173-254) can be selected in order to be able to overcome greater delivery heights


Description:

The Eccentric screw pump B70V-D 25.1 in the industrial version is a powerful positive displacement pump for medium, high viscosity and viscous media up to the limits of flowability. Depending on the application, various three-phase and air motors are available, which you can combine with the Pump tube at any time. This gives you flexibility at all times and saves important resources.

  • Cardan shaft versions also available in special immersion depths of 500 - 2000 mm
  • Media examples: viscous mineral oils, resins, emulsions, paints and many other thick materials. 

Features & Advantages

  • Uniform volume flow
  • Easy and fast cleaning
  • Gentle, low-pulsation product conveying
  • Smooth running and low wear
  • Large selection of robust and powerful drive motors

* The maximum flow rate is a value determined by means of a test bench and measured with water at a medium temperature of approx. 20 °C. The measurement is carried out at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.

** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
