Overview
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.

Multiplexing Capability
The simple design of Hydra-Cell enables mixing ratios of multiple fluids in flexible, economical ways. Using only one motor and one gearbox, Hydra-Cell Metering Solutions can provide spare, double flow, side-by-side systems, or premixed ratios. In fact, pumps utilizing the same gearbox and motor need not be the same model Hydra-Cell pumps. Up to six different fluids can be metered by using different manifold plates, and using special manifolds, a single Hydra-Cell P200 or P300 model can feed up to three systems from one liquid end. Ordinary metering pumps cannot provide the same capability without entailing the full cost of an additional pump.
Hydra-Cell Bare Shaft Pumps for Metering
In certain dosing applications, Hydra-Cell pumps without the gear reducers (bare shaft pumps) are an ideal alternative to metering pumps, as they meet or exceed API 675 performance standards at the rated RPMs outline in the table below.
Hydra-Cell bare shaft pumps should be considered instead of a Hydra-Cell Metering Solutions system when any of the following conditions apply:
- Flow capacities required exceed those of Hydra-Cell Metering Solutions pumps
- Space or application parameters dictate the use of direct or belt drives
- Acquisition cost is the primary consideration
