PUMPS

Centrifugal Pumps - Most pumps are centrifugal type that use a rotating impeller to add velocity to the liquid being pumped. Within the pump, the velocity of the liquid is generated by centrifugal force. Pressure is usually rated in feet of head for centrifugal pumps. This type of pump is used for liquids that are water like in viscosity (thickness), when quantities of flow are large compared to the pressure requirements. 

Centrifugal Pumps

Horizontal Pumps - These pump are mounted in a horizontal direction with the motor. They may be centrifugal or positive displacement. They require a seal to prevent the pumping solution from leaking past the rotating shaft. Shaft sealing can be of packing, mechanical seal, or magnetic driven.

Magnetic Drive Pumps

Self Priming Mag Drive Pumps

Vertical Pumps - These pumps are mounted in a vertical direction -- usually in or over the supply tank. The shaft sealing is normally a restrictive bushing that will limit the leakage up the shaft or may use a second impeller (expeller) to prevent solution migration up the rotating shaft. Magnetic driven - seal-less pumps are also available in this type of pump.

Vertical Submersible Pumps

Submersible Pumps - These pumps are mounted in the tank with the solution. The motor is normally contained in an oil filled cavity that is protected for contact with the liquid by a lip or mechanical seal. They can be designed to pump large solids or grind solids to smaller sizes, transfer waste water at large flow rates or high pressures, or just pick up water off the floor or the bottom of a tank. Often called sump pumps, they usually incorporate a float valve to automatically stop when the liquid level is low. Most submersible pump are centrifugal type.
