Product information “Eccentric screw pump tube B70V-SR Industry”

Delivery rate: 12 l/min. 
Drive shaft: Universal joint shaft (UJ)
Seal type: Mechanical seal (MMS)
Note: With Ex-approval


The Eccentric screw pump B70V-SR 12.1 (with reduction gear) in the industrial version is suitable for conveying water-like to highly viscous media with and without fibrous or solid materials. Depending on the application, various compressed air and electric 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.

  • PTO shaft versions also available in special immersion depths of 500 – 2000 mm
  • Pump tube equipped with Lutz original handwheel
  • Media examples: viscous mineral oils, resins, emulsions, paints and many other thick materials

* 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
