180034 Model NBR or FKM rubber membrane pump water diaphragm

180034 Model NBR or FKM rubber membrane pump water diaphragm

Model 180034 is a replacement rubber diaphragm listed with a 104 x 36 mm size reference and 95 g reference weight. NBR is the listed material; an FKM alternative requires review against the pumped fluid and operating conditions. Confirm the membrane profile and mounting features for the specific pump. Hydraulic accumulator applications and other pump model references require separate fit and design confirmation.

The original range table below is retained for identification. Entries with three dimensions use the original ID x OD x TH notation; two-dimension entries, including 180034, require labelled measuring points on a drawing. Send a sample or drawing for dimension confirmation and any custom-order requirements.

180034 Pump Diaphragm: 104 x 36 mm Reference

The 180034 entry contains two size values, 104 and 36 mm. Confirm what each value measures, together with the sealing rim, formed profile, centre attachment and any holes or inserts. Do not infer an inner diameter or membrane thickness from this two-value reference.

For a replacement inquiry, supply the pump manufacturer, full model and photographs of both sides of the original diaphragm. Keep the 180034 code with the drawing and check the mating seat and available travel before approving the sample.

Specify fluid composition, cleaning chemicals, continuous and peak temperatures, pressure differential, stroke and cycling speed for compound selection. Confirm hardness and any reinforcement on the approved specification; a generic flexible description does not define Shore hardness or operating limits.
