Triplex Single-acting Piston Diaphragm Pumps

Triplex Single-acting Piston Diaphragm Pumps

Our triplex single-acting piston diaphragm pumps (TPM) are the most widely used solution covering the whole range of pressures and flow rates.

In 1968, MHWirth developed the first triplex single-acting piston diaphragm pump, which is now a standard technology in the transport of highly abrasive media. Based on our long-term experience, we provide you with a well-established and reliable technology, that proves its benefits, especially in high-pressure applications.

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
  • High pressure capability reduces the number of pumping stations in difficult terrain
  • 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.
