De TETRA TDPK-serie: robuuste, efficiënte en gebruiksvriendelijke membraanpompen voor alle soorten vloeistoffen.

Technotrading has been selling diaphragm pumps for 35 years. Through this experience we know what works and what doesn't. Over the years we have seen all brands of diaphragm pumps go by: Graco, Wilden, DEPA, ARO, Sandpiper and Yamada. We still sell some of these brands. We have converted this experience into our own TETRA product: the TDPK series of diaphragm pumps. These pumps are unique because the air valve is completely built-in, making it well protected and more efficient compared to a conventional air valve. If something is wrong, the pump is easy to repair. At Technotrading we have all spare parts. We sell these pumps in the smallest and largest sizes from 0.5” (12.7 mm) to 4” (100 mm). There are three different materials. For the body this is stainless steel, aluminum and polypropylene. The membranes are available in Buna or in Teflon.

The TDPK diaphragm pumps in brief:

  • Inlet:1/2”, 1”, 1-1/2”, 2”, 3” of 4”

  • Outgoing: 1/2”, 1”, 1-1/2”, 2”, 3” of 4”

  • Body material: Aluminium, Stainless steel or polypropylene

  • Material of the membranes: Buna or Teflon

  • Pump output: from 1.85 m3 to 55 m3/h

  • Air consumption: 170 l/min to 8420 l/min
