W pump series

W pump series


Screw pumps with inlet funnel and lead screw.

  • Max. capacity: 100 m3/hr
  • Max. capacity: 1667 l/min
  • Max. capacity: 100000 l/hr
  • Max. discharge head: 240 m
  • Max. pressure: 24 bar



This series is ideal for pumping liquids with a high viscosity.The inlet funnel ensures that the liquid easily flows into the pump and then the lead screw pushes the liquid into the rotor casing chanber.

Depending on the liquid to be pumped and the desired pressure, various kinds of rotors and rotor casings are available in various constructions and kinds of materials. For the mechanical seal there are also many possibilities, including various packing materials, possibly with a single mechanical seal with, if necessary, a grease or oil chamber, or a rinsed double mechanical seal in various material combinations. For the housing you may choose from cast iron, stainless steelAISI 304, AISI 316 or special alloys.

The pumps are supplied with a relatively long drive shaft with 2 universal joints which keep the rotation angle as small as possible, improving the lifespan of the pump.

The pumps are available with a motor/gearbox that has a fixed speed, a motor with a mechanically variable speed or a variable frequency control which enables the speed to be controlled electronically
