Design & Development

Correct technical product selection is critical for application success.

If you attempt to use a formula one racing car on an off-road dirt track, or use a tractor on the express way, the result will not be good.

It is exactly the same in mechanical seal selection. Selecting the correct seal face materials, elastomers and seal design is fundamental for application sealing success.

Correct product selection is largely dependent on partnering with a company which employs skilled, knowledgeable and experienced people who can make timely, sound decisions to maximise the client value-added experience.

24-7 support


Process equipment breakdown requires urgent supplier reaction. Murphy's law states that if something can go wrong it will go wrong exactly when you don't want it.

Unpredictable equipment breakdown is, by its very nature, unpredictable.

When a customer process line is down and losing thousands of Dollars / Euros / Lach Rupees per hour that customer needs a supply partner that is ready and mobilized to provide exceptional customer service.

24-7 manufacturing support is critical to providing urgent customer support.

Seal Repair and Refurbishment

Repair & Refurbishing

Refurbishing all makes of mechanical seal provides client peace of mind.

Over time, large process plants accumulate a variety of mechanical seals types in both their store and in operational service, installed on rotating equipment. This can create a major headache for plant engineers.

Reliability Engineering provides a turnkey seal and pump refurbishment service to remove plant operative headaches and ensure our customers get the high levels of customer service they need and require, irrespective of seal type and make.
