Reciprocating Metering Pump

Reciprocating Metering Pump

High-Precision Dosing for Extreme Pressure, Temperature, and Hazardous Fluids

Sakura’s Reciprocating Metering Pump is engineered for applications where absolute dosing accuracy, high pressure, and reliability are critical. Designed to deliver ±0.5% discharge accuracy, it ensures stable, repeatable flow control even under extreme operating conditions.

With support for high-viscosity fluids, slurries, liquefied gases, and hazardous substances, this pump is trusted across chemical processing, energy, water treatment, and heavy industrial systems.

What Is a Reciprocating Metering Pump?

A reciprocating metering pump is a positive displacement pump that delivers a precise volume of liquid with each stroke. Flow rate is controlled by adjusting stroke length or operating speed, allowing accurate proportional dosing regardless of pressure fluctuations.

Sakura’s design focuses on high-pressure stability, long-term accuracy, and safe handling of aggressive or hazardous fluids.
