Centrifugal pumps consist of a set of rotating vanes, enclosed within a housing or casing, that are used to impart energy to a fluid through centrifugal force.
Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).
Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly.
Plastic pumps are designed to move fluids that would corrode or damage other types of pumps. They provide broad chemical resistance and are less costly and lighter in weight than metal pumps.
Positive displacement pumps use a mechanical force such as gears, bladders, pistons, plungers or diaphragms to push liquid through and out of the pump.
Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.
Turbine pumps are centrifugal pumps that use pressure in combination with a rotary mechanism to transfer fluid. They typically employ blade geometry, which causes fluid circulation around the vanes to add pressure from inlet to outlet.
