Pump Packing

Pump packing is ideal for the controlled leakage required for certain applications. ​Chesterton offers extensive applications ​expertise in pump packing solutions for rotating equipment—including design, selection, installation, testing, and more.

Our  innovative and award-winning packing solutions reduce power requirements for the pump and result in less leakage—lowering the total life cycle costs of the pumping system. ​

Mechanical Seals

Our innovative, award-winning mechanical seals for pumps, agitators, mixers, and other rotating equipment simplify installation, improve reliability, and extend the performance of fluid handling. Companies around the world turn to A.W. Chesterton Company for extensive expertise in mechanicals seals — in design, selection, installation, field service, and more.

Rotary Seals

Advanced Protection

Rotary seals are designed to extend bearing life and save money by reducing downtime and increasing reliability. Chesterton's rotary seals range from face sealing-type arrangements to advanced lip seal designs.​

Gaskets & Joint Seals

Gaskets prevent leakage of liquids or gases by forming impervious barriers between mating surfaces. From standard sheet gaskets and metal to custom moldable polymer gaskets, Chesterton has you covered.

Valve Stem Packing

Valve stem packing plays a critical role in overall valve performance. Reducing or eliminating process leakage is critical not only to process performance but also to employee safety, regulatory compliance, and profitability.

Whether  you are dealing with high steam, high pressure, or caustic chemical conditions, you can rely on Chesterton sealing specialists for applications expertise and innovative valve packing products to help your company realize optimal valve performance.

Flange Gasket Sealing

Many factors must be considered when choosing the proper gasket for an application, including safety, temperature, pressure, the media to be sealed, equipment conditions, versatility of the product, and cost.

System One Centrifugal Pumps

The simplest type of centrifugal pump is the single stage machine that consists fundamentally of a rotating element, called an impeller, and a casing. Liquid is led to the eye or center of the impeller and is set into rotation by the impeller vanes. By virtue of centrifugal force the liquid is thrown from the rim or periphery of the impeller with a considerable velocity and pressure. The casing, which closely surrounds the impeller, has a volute shaped passage of increasing area, which collects the liquid leaving the impeller, and converts a portion of its velocity energy into additional pressure energy. This casing passage leads to the discharge nozzle of the pump where it is forced into the discharge piping.
