Pump Technology Details
External Gear – Cavity Style
Consists of two or more rotating gears which mesh together. One of the gears is turned by a power source and drives the other gear(s). The spaces between the gear teeth carry the fluid from the inlet to the outlet. The gear mesh point prevents the fluid from returning to the inlet. Gear pumps are available in cavity and suction shoe styles, both of which provide pulseless delivery.
External Gear - Suction Shoe Style
Our trademark suction shoe pressure-loaded gear pump design features a “suction shoe” that allows the pump to self-compensate for wear. Suction shoe pumps maintain high-volumetric efficiency, even at elevated pressures. Additional benefits include near-zero slip for accurate metering, long life, and more stable performance as pump components wear or thermally expand.
Centrifugal pumps offer a reliable, simple, long-lasting design for higher flow applications. Using the unique magnetic drive technology, centrifugal pumps provide excellent chemical resistance and energy-efficient fluid delivery. Integrated impeller and magnet assemblies reduce the number of rotating parts to maximize pump life.
Centrifugal pumps consist of an impeller rotating within a casing. Liquid directed into the center of the rotating impeller is picked up by the impeller vanes and accelerated to a high velocity. When the liquid in the impeller is forced away from the center of the impeller, a reduced pressure is produced and consequently more liquid flows forward. There is no closed volume, as in a positive displacement pump, therefore producing a steady flow through the impeller. The pump basically increases the Bernoulli head of the flow between the eye and the exit of the pump.
