Diaphragm Process Pump Zentriplex

Capacity range 424 – 8,000 l/h, 367 – 36 bar

The Zentriplex guarantees excellent performance and provides outstanding efficiency as an oscillating triplex process diaphragm pump, with an extremely small footprint thanks to the space-saving arrangement of the pump and drive unit. It also stands out on account of its efficiency, as minimal material and labour are required.

Product description

The innovative process metering pump with the ideal dimensions and excellent efficiency.

The Zentriplex is an oscillating process diaphragm metering pump, which has a very small footprint thanks to its unconventional design, as the pump and drive unit are mounted above each other to save space. Diaphragm dosing heads and hydraulic units are arranged in a star pattern around the drive unit, resulting in minimised loads and significantly lower material and drive requirements. The Zentriplex is designed in compliance with API 674.

Your benefits

Excellent conservation of resources:

  • Excellent energy efficiency.
  • Diaphragm replacement without dismantling the suction and discharge lines ensures cost-effective maintenance of the pump
  • Low noise emissions
  • Very quiet thanks to complete balancing of masses
  • Only one connection required by the customer. Collective discharge and suction lines are integrated in the pump
  • Low flow rate pulsation
  • ProMinent Process Metering Pump Zentriplex
