Liquid Dispensing and Metering System Ideal for Clinical Labs

A valveless liquid dispensing and metering system utilizes dual fluid metering pumps synchronized to eliminate pulsation present in other piston pump designs. It is suitable for those labs when there is a need to dispense small quantities of liquids with a pulse-free stream.

The new Smooth-flo PDS100 system is intuitive, menu-driven, and uses convenient front-panel membrane switches and a large liquid crystal display (LCD) display for programming. The system features pulse-free fluid delivery down to 15 μl/min continuous flow. The precision dual stepper controlled pumpheads are calibrated to the users' flow range.


Pump heads are integrally mounted to the control unit, which includes stepper motors, drivers, and programmable electronics housed in an anodized aluminum enclosure. This enclosure is suitable for wall mounting or bench top installation in the laboratory or production areas.

Introduced by Fluid Metering, Inc. (Syosset, NY, USA), the Smooth-flo PDS100 System offers RS485, 4-20 mA, 0-5V and 0-10 V electronic control interface for connection to process sensors, PLC and PC control systems. The system includes tubing, fittings, and configuration instructions for Smooth-flo PDS100 System operation. Universal Power Input operates on 100-240 VAC 50/60 Hz.
