Griswold’s H Series

Griswold’s H Series

Griswold’s H Series consists of high-pressure pumps that are ideally suited where clean water needs to be delivered at high pressures. Unlike the standard end suction centrifugal pump, the Griswold H series maintains its prime even after check valves fail. The suction line is located at the higher part of the pump housing, keeping the impeller and mechanical seal covered with water at all times.

PUMP

Principle of Operation

Centrifugal pumps are used to induce flow or raise a liquid from a low level to a high level. These pumps work on a very simple mechanism. A centrifugal pump converts rotational energy, often from a motor, into energy in a moving fluid. 

The two main parts that are responsible for the conversion of energy are the impeller and the casing. The impeller is the rotating part of the pump, and the casing is the airtight passage that surrounds the impeller. In a centrifugal pump, fluid enters the casing, falls on the impeller blades at the eye of the impeller, and is whirled tangentially and radially outward until it leaves the impeller into the diffuser part of the casing. While passing through the impeller, the fluid is gaining both velocity and pressure.
