Duplex Double-acting Piston Diaphragm Pumps

Duplex Double-acting Piston Diaphragm Pumps

Our duplex double-acting piston diaphragm pumps (DPM) are a field-proven solution to cover the whole range of pressures and flow rates. They are especially applied to transport high volumes.

Main applications

  • Tailings transport, e.g. for oil sand, iron, copper etc.
  • Pipeline slurry transfer, e.g. for iron ore, copper, zinc concentrate etc.
  • Digester and autoclave feed
  • Mine dewatering
  • Fly ash transport

Performance chart



  • 75 % OPEX savings compared to traditional pump systems
  • Up to 15 % less downtimes when using the Wirth Pump Monitoring System (WPMS™)
  • Up to 50 % less suction pulsation, compared to other piston diaphragm pumps in the market


Our extensive project experience and execution provide complete drilling systems and equipment on an Engineering, Procurement, and Construction basis.
