RAM supplies flexible seals for pump manufacture, pumping equipment, housing and pipework.

Types of pump application.

Pump gaskets cover the whole gamut of sealing materials, from hot/cold liquids, high pressure, vacuum, vibration and aggressive chemicals to food safety and heat transfer applications. The list goes on and each product requires material suitable for a variety of different applications within the same unit.

RAM supports the technical choice of materials within pumping manufacture and supplies replacement gaskets for pumps and bespoke one-off parts for breakdown repair. RAM also supplies O-rings for mechanical seals and secondary leakage.  Pump housing seals are supplied for new parts in large volume or replacement parts.

Pump sealing problems?

Abrasion, secondary leakage, lubrication, stability under load, viscous and setting materials (such as crystallisation) etc;

Pumping applications commonly have more than one issue that needs to be considered when designing seals. The material/fluid the pump is sealing against and the mechanical type of pump, e.g., centrifugal or reciprocating, shaft diameter and horizontal or vertical mounting are one of a number of things to consider when replacing gaskets, o-rings or packings.

If you are having issues sealing, whether it be in the pump module itself (shaft seal, valve seal, packings) or within pipework, housing or extenuating machinery we can help. We can provide advice on our huge range of materials, supplying small volumes for testing and one-off repairs. Often issues in machinery can be specific to each case, depending on the pressures, workload and intention of your production. The team at RAM is happy to discuss and help you to fix the problem.

Fluid types in pumping applications.

  • drinking water
  • food processing
  • boiler feed water
  • sea and brackish water
  • hot water
  • condensate
  • lyes
  • oils, synthetic and mineral
  • heated mineral oils
  • heated synthetic oils
  • heat transfer applications
  • air
  • vacuum
  • oils and viscous chemicals like isocyanate.

Certification is easily supplied with all products ordered from RAM if required

  • Food Standards | FDA
  • Potable Water | WRAS
  • FAIR
  • Certificate of Conformance

Using packing – pre-mechanical seals.

RAM gaskets supply packings. Using equivalents/distribution for Klinger, Rotatherm, Flexitallic, Chemstar, Isatherm, Thermoflon, Buramex, Buratex, Araflon, Aquistar, Alchem and more.

Carbon and graphite packings have a wide temperature capability, they are difficult to degrade chemically and are low friction. Synthetic packings are used where non-carbon/graphite and non PTFE is required.

Cellulose fibres are still occasionally utilised today although less so as modern materials last longer. Natural fibres provided for packings include flax, cotton, hemp, jute, lead and aluminium.
