HMT Triplex Piston Diaphragm Pump

Diaphragm pumps for difficult media.

THE ABEL HMT is a single-acting, slow-running, dry-run secure triplex piston diaphragm pump.

Very high operating pressures in connection with increased flow rates create special environments for pump specifications. When abrasive materials with an increased percent solids content are present, many industrial partners decide on an ABEL HMT.

The HMT Pumps are also equipped with pre-formed diaphragms to the same specifications as the whole ABEL HM range. The superb resistance qualities of the special diaphragms are constantly demonstrated throughout the whole pumping process as there is no evidence of stretching or shrinking.

The pumps in the HMT range are equipped with API cone valves and are also available for reverse-flow for nonstable sedimentary slurries.

  • The ABEL HMT-range is designed with a Triplex-Transmission gear with a 120° crank displacement which enables an optimal, even volume flow
  • This simple operating, slow-running Triple Piston Diaphragm Pump operates safely, even when dry
  • Able to demonstrate a performance with reduced pulsation and ease of operation, despite the increased operating pressures of up to 25.0 MPa.
  • Provides a clever solution to pumping suspensions that have high dry substance content and a high specific weight
