P Series Metering Pumps

  • Specifications
  • Other Info
  • Case Studies


The Hydra-Cell P Series are sealless, positive displacement pumps featuring multiple diaphragms for virtually pulse-free, linear flow. They are designed for applications requiring precise metering, dosing, injection, or mixing. Hydraulically-actuated, balanced diaphragms provide superior performance across the full operating pressure range (up to 173 bar with metallic pump heads or 24 bar with non-metallic components). Electronic flow control increases accuracy and reliability and a duplexing option doubles capacity, offering equipment savings.

Hydra-Cell metering pumps can be equiped with a variety of diaphragm materials (FKM, Buna-N, EPDM, Neoprene and PTFE). In addition, several Hydra-Cell metering pump head options are available including Stainless Steel, Hastelloy C, Polypropylene and PVDF. This enables Hydra-Cell metering pumps to handle a wide range of fluids from clear water to thick slurries.

P Series pumps meet and, in most cases, exceed API 675 performance for controlled-volume, positive displacement pumps.
