Valveless Metering Pumps

The valveless metering pumps supplied by Fluid Metering take care of precision dispensing of additives for food processing applications. Addition of vitamins, colors, flavors, fragrances, enzymes and preservatives are typical ingredients, which benefit from FMI's valveless piston technology.

Often in concentrated form, the pump's precision of 0.5% ensures product consistency, while eliminating waste of expensive ingredients.

The patented valveless CeramPump pumping principle utilizes one moving part, a sapphire-hard ceramic piston, to perform all fluid control functions, eliminating valves typically present in other low volume metering technologies. Elimination of valves, as well as having dimensionally stable ceramic internals, results in a pump that will provide millions of maintenance-free dispenses without the need for recalibration.

The IVSP Industrial Variable Speed Metering Pump is a good choice for viscous fluids. It has a rugged 1/4 HP variable speed drive motor and available with sanitary quick-disconnect fittings. Speed is controlled via a DIN mountable controller for both manual and electronic speed control.

The valveless function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a precisely mated ceramic liner. The reciprocation action of the piston, similar to a standard piston pump, accomplishes the pumping function. However, that's where the similarity ends.

The piston also rotates, alternately aligning a flat at the end with the inlet and outlet ports of the pump. When the flat is aligned with the inlet port, fluid can be drawn into the pump. When the flat is aligned with the outlet port, fluid can exit the pump. Only one port is open at any time and at no point are both ports interconnected. This effectively functions as, and replaces, conventional check valves.
