After years of service, the trough and the body of a screw pump can be subject to significant wear because of strongly grinding materials such as sand and gravel held within the sewage or media.

When the increased gap between the screw pump body and the trough starts to have a negative effect on the operational efficiency, a complete overhaul of the system should be considered.

Spaans offers a choice of three refurbishment options:

  • Refurbishment of the screw pump body and renewal of the concrete trough.
  • Refurbishment of the screw pump body and replacement of the concrete trough with a steel liner.
  • Refurbishment of the screw pump body and installation of a self-supported steel liner in the existing trough.

Refurbishments are carried out at the company's factory in Balk to ensure the highest quality welding, shot blasting and corrosion protection.
