Triplex Double-acting Piston Diaphragm Pumps

Triplex Double-acting Piston Diaphragm Pumps

Our triplex double-acting piston diaphragm pumps (TDPM) achieve very high flow rates in the transport of abrasive slurry. They combine the well-established triplex single-acting configuration with the duplex double-acting pumping principle. The TDPMs are therefore are equipped with three pistons working on both sides of the piston body. This configuration offers an economical solution for high flow rates at medium pressure.

Our powerful TDPM offers a feasible alternative to multistage centrifugal pump systems. It requires only one single pump station for medium pressure applications. In addition, each pump can transfer a volume that is up to 100% higher than that of the largest conventional piston diaphragm pumps. This provides additional benefits such as higher efficiency and availability, and it reduces spare parts consumption.

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 feed

Performance chart


  • Up to 50 % CAPEX savings with our TDPM™ technology due to fewer pumps required
  • Up to 100 % higher transfer volumes compared to the largest conventional piston diaphragm pumps


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