PUMP SEAL SUPPORT SYSTEMS AND SOLUTIONS
Pump seal support systems
OVERVIEW
With over 100 years of experience in developing technologies that optimise rotating equipment performance, John Crane understands mechanical seals.
We know reliable seal performance is necessary to maximise process efficiencies and meet production targets and constantly evolving, stringent operational requirements.
Our expert engineers have designed a range of fluid control and pump seal support systems that create the optimal operating environment, enabling the dependable performance expected from a John Crane seal.
No matter what the process fluid, from liquids to gases, cryogenic to boiling and abrasive to the purest finished product, our pump seal support system components, such as barrier fluid reservoirs, heat exchangers, abrasive separators and pump seal gas control panels, support the most complete spectrum of industrial processes.
Compliant with global industry codes such as API, ASME VIII and ASME B31.3, our systems can also be designed and built to meet regional specifications such as AD2000, ATEX, CE, PED, SELO and GOST.

Common questions
How do I choose the proper seal support system for my application?
Selecting the right solution depends on fluid type, operating pressure, temperature, environmental regulations and the mechanical seal arrangement. Contact John Crane specialists to assess your process needs and recommend a tailored system that optimises seal performance, safety and compliance.
What industries use pump seal support systems?
Pump seal support systems are essential in industries handling challenging fluids, including oil and gas, chemical processing, power generation, pulp and paper, and food and beverage. John Crane solutions are designed to support both general-purpose and mission-critical operations.
How do seal support systems improve mechanical seal reliability?
Seal support systems regulate barrier fluids, heat removal and gas flow to maintain a stable sealing environment. By controlling these variables, John Crane mechanical seal support systems minimise face contact, reduce thermal stress and prevent process intrusion, resulting in longer seal life and improved equipment uptime.
