​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton is the world leader in design innovation of split seals. Our innovative split seals have been used to seal thousands of process-critical pieces of rotating equipment with exceptional​​ ​results and many years of leak-free operations.

Chesterton was the first company to offer commercially-viable split seals for plant-wide use, which revolutionized pump sealing across industries. Since that time, we"ve launched a number of innovative split seal designs now used as a standard by companies around the globe.​ We offer shaft diameters ranging from 25-914​ mm (1-36 in.)​

​A split seal has components split into two equal halves which are secured as one unit on the seal shaft. The major advantage of the split seal design is that it allows you to install the seal with no dismantling of the pump (or equipment)—an enormous time-saver! Chesterton"s split seals offer virtually leak-free performance. This leads to improved safety and environmental compliance and nearly eliminates sleeve wear, and flush water usage,  among many benefits.

Keep Supply is your source for Cornell Pump seals, seal parts and tools. Cornell Pump seals offer multiple methods of stopping leakage around the drive shaft of an end-suction centrifugal pump.

Mechanical seals consist, in their most basic form, of two flat faces (machined within light bands tolerance): a rotating element that spins with and seals the pump shaft, and a static element that presses into the backplate casting and seals the liquid from escaping to the atmosphere. The central advantage that mechanical seals possess over traditional packing is that they almost completely negate all forms of leaking in a pump.

Lip seals consist of a rubber ring, slid over the shaft. They are useable in low differential pressure and low operating speeds. Lip seals do leak, but not as much as stuffing.

Centrifugal pumps and their mechanical seals and seal support systems are critical components of just about every process industry in California, including chemical and petroleum, semiconductor, oil and gas, gas and water utilities, and power generation. The number of pumps in operation can range from a handful in a pumping station to hundreds throughout California refineries. The challenges in maintaining these pumps and systems increase proportionately to the variety of pumping processes in operation.

Considering the criticality of pumps, mechanical seals, and seal support systems, I advise my clients to take the analytical approach toward vendor evaluation. And rather than create a lengthy list of evaluation criteria, I recommend they start with a shortlist of important factors to consider when choosing among mechanical seal support brands currently available on the market.

Your mechanical seal support vendor should possess deep industry knowledge and experience. That comes from decades of experience in serving the mechanical seal support system design, fabrication, and support needs of your specific industry. That experience should encompass:

Technical understanding, not only of pumps, mechanical seals, and seal support systems, but also the upstream and downstream infrastructure and operating conditions that are critical in determining the optimum seal support system design.

Industry experience is one of the most important factors in ensuring that the solutions your vendor is providing are carefully matched to your specific process requirements. Standing behind the best mechanical seal support brands is a team of knowledgeable and experienced technical professionals.

The quality of components that comprise your mechanical seal support systems is critical to long-term performance and reliability. Materials used to manufacture parts and components should be selected for their ability to withstand the expected range of operating conditions. Components and parts should be manufactured following recognized quality control standards.

Your mechanical seal support vendor should be able to provide you with detailed specifications for any of the parts or components used in a mechanical seal support system.

The real value of a mechanical seal support system comes from expertly assembling the parts and components to create the system that precisely meets the requirements of each pumping process. Vendors’ assembly practices are certified to the ISO 9001 quality management standard.

In choosing a mechanical system seal support brand, you also want to make sure they carry the range of seal support systems to match all your pumping process needs and can customize each system to maximize performance and reliability. Even though you may currently have a limited number of pumping processes, you want a vendor that can cover a wide range of mechanical seal support requirements. This includes process side (flush), between seal (buffer/barrier), and atmospheric side (quench) mechanical seal support systems.

In addition to the standard API 682 Plans, your vendor should also provide optional components such as pressure and temperature gauges, flow meters, transmitters, strainers, cyclone separators relief valves, level gauges, and flush fluid cooling systems. With the proper design, any one or more of these components can significantly enhance the performance and reliability of a mechanical seal support system.

The design of the optimum mechanical seal support system involves far more than just the assembly of parts and components per a specific API plan. A properly designed mechanical seal support system also considers factors that promote safe operations and reduce maintenance costs.

A bypass loop included in the mechanical seal support system design can deliver a continuous supply of flush fluid whenever filters are replaced or cleaned. With this design addition, you don’t need to halt the pumping process just to perform planned maintenance

High-point vents allow seal support systems to easily be vented to clear entrapped air that could impede flush flow. Design elements like these can reduce downtime. And when you have dozens to hundreds of pumps in operation, add up to significant savings in maintenance time and costs.

Consider the benefits of a global mechanical seals support vendor that also has a local presence. This can be one of the most important factors in choosing a mechanical seal support brand. A global reach and local presence give you the added advantages of:
