WILDEN PUMP SPARES

Spares

Wilden Pumps are well known throughout a multitude of industrial sectors for their rugged design, reliable service and unmissable orange colouring. You can find these pumps in all sorts of tasks from food processing, to water evacuation duties and nuclear waste processing! Wilden Pumps have a variety of different elastomer materials to choose from.

Thermoplastic Elastomers (TPE)

Polyurethane

An excellent general purpose diaphragm for use in non-aggressive applications. This material exhibits exceptional flex life and durability. Wilden’s most economical diaphragm.

Wilflex

Made of Santoprene, this diaphragm is an excellent choice as a low cost alternative to PTFE in many acidic and caustic applications such as sodium hydroxide, sulphuric or hydrochloric acids. Exhibits excellent abrasion resistance and durability at a cost comparable to neoprene.

Saniflex

Made of Hytrel, this diaphragm exhibits excellent abrasion resistance, flex life and durability. This material is FDA approved for food processing applications. An outstanding general purpose diaphragm as well.

PTFE Elastomers

PTFE

Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Wilden’s PTFE diaphragm exhibit good flex life. Wilden also offer PTFE integral piston diaphragms that offer superior product containment. The smooth contoured shape makes this diaphragm an excellent choice for sanitary or ultra pure applications.

Rubber Elastomers

Neoprene

An excellent general purpose diaphragm for use in non-aggressive applications such as water based slurries, well water or sea water. Exhibits excellent flex life and low cost.

Buna

Excellent for applications involving petroleum/ oil based fluids such as leaded gasolines, fuel oils, hydraulic oils, kerosene and motor oils.

EDPM

Excellent for use in applications requiring extremely cold temperatures. May also be used as a low cost alternative for pumping dilute acids or caustics.

Viton

Excellent for use in applications requiring extremely hot temperatures. May also be used in aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. PTFE would normally be used with these aggressive fluids as its flex life is better than Viton. However in applications involving suction lift outside the range of PTFE, Viton will be the preferred choice for highly aggressive fluids.
