The Metering Pump - Valveless Piston Pumps

We aim to respond within 1 hour

Flow rate can be calibrated 20-400mL/min ± 5%
Ideal for dialysis equipment, analytical instruments and clinical analysers

Description

The Metering Pump that is ideal for OEM and medical equipment applications. It features a 24V brushless DC motor without requiring an additional driver. The pump comes with either a fixed speed motor (2000 RPM) or variable speed motor (ranges from 0 to 17000 RPM), both featuring bidirectional rotation (calibrated clockwise). Its flow rate can be calibrated from 20-400mL/min ± 5%.

Suitable for a majority of medical applications, the valveless fluid control features only one moving part of the fluid path and the inert fluid paths enables maximum chemical compatibility. Internal components are sapphire-hard and constructed from dimensionally stable ceramic. Long pump life is guaranteed as it maintains calibration precision of 0.5% for millions of maintenance-free cycles.

Operating pressures and temperatures

A wide temperature range of between +20°C and 60°C allows for use within multiple different industries.
