Nitrile Or FKM Rubber Diaphragm Pump Membrane OEM ODM Custom Service
Nitrile or FKM Pump Diaphragms — Custom Membrane Drawing and Compound Selection
Custom Pump Diaphragms: Approve the Formed Profile and Rubber Grade Together
| Custom specification | Detail for drawing and sample approval |
|---|---|
| Pump reference | Provide pump manufacturer, model, revision and original membrane reference. |
| Formed membrane | Specify OD, rim, thickness, formed height, centre attachment and tolerances from drawing or sample. |
| Rubber selection | Identify NBR or FKM grade and hardness; approve against the actual liquid and exposure temperature. |
| Construction | Define reinforcement, backing or inserts where required; confirm which face contacts the fluid. |
| Acceptance | Agree dimensional checks, fit review and application test conditions before production. |
The original 68–140 g range covers different membrane references; confirm the selected part weight. NBR and FKM versions are separate material specifications. ISO 9001 applies to quality management; pump operating limits follow the original equipment specification.
A pump diaphragm is a flexible replacement component selected for a specific pump design. NBR (nitrile) or FKM requires the approved grade for the pumped fluid, temperature and operating conditions. AR40, AR70 and D30 are enquiry references requiring manufacturer and revision confirmation. Hydraulic accumulator diaphragms are separate components and must not be substituted from appearance. The table below retains the original part references; it is not a dimensioned drawing.

Quote the part reference with pump manufacturer, model and revision. Confirm membrane OD, formed height, thickness, clamping rim and centre attachment from a drawing or sample. For a seal kit, agree the individual parts and quantities; photographs and reference codes alone do not define kit contents.
