Hydra-Cell Metering Pumps with Virtually Pulseless Flow

Posted: Tuesday 6th March 2018

Pulsation can be a major problem with reciprocating metering and dosing pumps, potentially causing component failure through fatigue or simply leakage in discharge pipe work due to pipe strain.

Equally important, the pulses can cause inconsistencies in flow rate that are unacceptable in many in-line process applications.

The unique multi-diaphragm arrangement of Hydra-Cell metering & dosing pumps removes the need for pulsation dampeners in most situations. Having multiple diaphragms in a single pump head, operating sequentially and each pumping a relatively small volume of liquid at a greater frequency, virtually eliminates pulsation.

The cost of additional pulsation dampeners and their on-going maintenance is avoided in most instances and systems become more reliable.

The Hydra-Cell metering and dosing pump range can accommodate measured flow requirements from 0.23 to 6360 lph at pressures of up to 245 bar. Hydra-Cell pumps also exceed API 675 performance requirements in terms of repeatability, linearity and steady state accuracy, and are able to pump abrasives and liquids that contain solid particles reliably due to its unique check valves and can even run dry indefinitely without suffering damage.
