PRODUCT INFORMATION

The Verderhus pump was developed to be highly efficient and offer low operation costs. The special impeller ensures a high efficiency, also when pumping thicker fluids, and a wide passage/outlet. The solid design of the pump also reduces maintenance costs.

This screw channel pump includes an impeller that is formed as a corkscrew, within a cone-shaped casing. Through the rotation of the screw, the fluid is literally being pushed away. The cone form of this pump ensures a blockage free operation.

Materials of construction
Sealing
  • wear resistant double mechanical seal with oil chamber, in standard execution with hard metal seal surfaces at the fluid state 
  • gland packing 
Motors

IEC motors are standard with the Verderhus series. However, a wide variety of motor choices are available if your application requires it. 

Options

There are a wide variety of options available for the Verderhus range, to ensure abrasive, corrosive and cavitation resistance.

The GPT can be used to protect pumping chambers and down-stream stormwater detention tanks or treatment devices. Multiple units can be installed to ensure effective site coverage and maximise first flush catchment.  

Based on Global Water’s proven glass-reinforced concrete (GRC) 600 mm x 600 mm sumps, the EcoTreat GPT offers optimum versatility, with the outlet able to be installed on-site at any invert to suit site requirements.  

A galvanized grate suitable for pedestrian or light vehicle traffic is supplied as standard. A heavy-duty grate is available as an option.
