Positive Displacement Pump
ABEL has been manufacturing and developing oscillating positive displacement pumps in single and double-acting design for several decades. The oscillating movement of the piston is used to displace a medium. In the positive displacement pump market, ABEL has specialized in piston diaphragm pumps and plunger pumps.
Which pump type is most suitable for you depends on the details of your pump application (medium, flow rate, pressure, etc.). We will be happy to advise you.

ABEL Positive Displacement Pumps at a Glance
Diaphragm Pump and Piston Diaphragm Pump
Diaphragm pumps have an extremely robust design and reliably handle critical pumping tasks. The key to this is the diaphragm, which separates the medium from pump components. This means that aggressive, abrasive and toxic media can also be pumped without any problems. On the one hand, the design ensures a high level of process and operational reliability and, on the other hand, results in low-maintenance operation, as only a few components actually come into contact with the pumped medium. Overall, this results in very low maintenance and operating costs.
In addition, ABEL diaphragm pumps are particularly energy-efficient and achieve an efficiency of up to 90%. The robustness also becomes clear when considering which sludges the positive displacement pumps convey – with piston diaphragm pumps, the upper limit of the possible solids content in the sludge is 75%.
Piston Pump and Plunger Pump
Piston pumps and plunger pumps work without a diaphragm. This means that the piston or plunger is in contact with the pumped medium. The plunger pumps of the HP & HPT series are therefore suitable for applications with clean or only slightly contaminated media at high pressure. The plunger pumps also achieve an efficiency of up to 90%.
The SH solids handling pump, a piston pump, rounds off the ABEL pump range.
