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.
Griswold's 811CC Series
The 811CC (Close-Coupled) Series Centrifugal Pumps match the features, flexibility, and performance of standard 811 ANSI pumps while incorporating a compact, space-saving design that offers significant benefits. These pumps utilise an ANSI-dimensional liquid end that easily adapts to existing ANSI installations.
This means that the pump can “drop” right in line with the use of existing piping, providing an easy and economical replacement for most ANSI installations.

Griswold's 811SP Series
The 811SP Series are self-priming centrifugal pumps available in various sizes, capacities, and materials to fit virtually any process fluid application. With double the wear area of enclosed models, the 811SP Series impeller offers superior handling of solids, corrosives, and abrasives. Back pump-out vanes reduce hydraulic loads and seal chamber pressure.
They come with a wide range of sealing options coupled with seal chambers and stuffing boxes selected for service conditions to improve lubrication and heat dissipation of seal faces, maximising pump uptime.

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.
