Range Of AODD pump diaphragmsKeywords:Tri-Ark, Pumps

A new range of low cost diaphragms for air-operated double diaphragm (AODD)pumps has been announced by Tri-Ark Ltd, a leading independent supplier of AODD pumps and components to UK industry (Plate 6).

With over 35 years experience in the pumping and chemical industry, Tri-Ark reports that it has been able to specify precisely the material used to give optimum performance. The new diaphragms are manufactured from a specially modified PTFE material.

This particular formulation is believed to show excellent resistance to aggressive fluids and has a wide operating temperature range. The static and dynamic friction coefficient are numerically equal, preventing "stick slip".

Modified PTFE claims a number of benefits compared with normal (homopolymer)PTFE, and, in particular for diaphragm applications, has good deflection characteristics. This claims excellent durability and reliability in use and allows higher flow rates to be accommodated.

Pumps for which the Tri-Ark diaphragms are currently available are 1" and 2"S and PIPER® pumps from Warren-Rupp and 1.5" and 2" AODD pumps from Wilden®.
