Fluid Metering IVSP Industrial Variable Speed Metering Pump

The Fluid Metering IVSP Industrial Variable Speed Metering Pump is a valveless pump for dispensing of additives for food processing applications.

The pump is suitable for viscous fluids, including vitamins, colours, flavours, fragrances, enzymes and preservatives. For ingredients that are added in concentrated form, the pump’s precision of 0.5% ensures product consistency, while eliminating waste.

The pump uses one moving part, a sapphire-hard ceramic piston, to perform all fluid-control functions. The valveless function is accomplished by the synchronous rotation and reciprocation of the ceramic piston within a ceramic liner. The reciprocation action of the piston, similar to a standard piston pump, accomplishes the pumping function.

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.

The elimination of valves results in a pump that will provide millions of dispenses without the need for recalibration.

The pump has a ¼ HP variable-speed drive motor and is available with sanitary quick-disconnect fittings. Speed is controlled via a DIN-mountable controller for both manual and electronic speed control.
