Metering Pump with VFD/Motor Controls

September 27, 2010
The metering pump comes with enhanced pumping elements and integral VFD/motor controls. These features help expand the scope of metering applications and enhance economical and efficient performance when metering low-flow liquids in a wide range of processing applications including dosing, sampling and metering. The integral VFD/motor controls will improve metering accuracy and repeatability. The progressing cavity design of the metering pump results in a smooth flow, free from pulsations and variations in velocity and volume to prevent material waste or mixture imbalance, according to the manufacturer. Additional advantages and features of the metering pumps include: pressures to 300 psi; precise flow control at low RPM; visible, ergonomical LED external displays; and capacities from 0.1 to 400 GPH. The pump is available in bare-shaft and close-coupled configurations. All models are capable of handling a wide variety of fluids from clean, clear liquids to abrasive, corrosive fluids, solids in suspension and viscous materials.
