NBR And FKM Membrane Widely Used In Agriculture And Hydraulic Systems
NBR and FKM Pump Membranes — Agricultural Pump Service and Hydraulic Component Identification
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.

| 1040081 | 550080 | 550190 | 202001(IP) | 904008 |
For agricultural pump replacement, quote the manufacturer, model, part reference and actual liquid formulation. Confirm membrane OD, formed height, thickness, clamping rim and centre attachment from a drawing or sample. For a hydraulic enquiry, identify whether the part belongs to a pump or an accumulator before choosing the membrane; their geometry and operating requirements are different.

Agricultural and Hydraulic Membrane Orders: Identify the Equipment and Fluid First
| Equipment | State pump manufacturer, model and revision; identify an accumulator separately. |
|---|---|
| Working fluid | For agricultural use, provide the actual liquid or chemical formulation, concentration and cleaning fluid. For hydraulic use, specify the hydraulic fluid. |
| Membrane geometry | Confirm outside diameter, formed height, thickness, clamping rim and centre attachment to the drawing. |
| Rubber selection | Approve the NBR or FKM compound for the actual fluid, temperature and flexing duty; material name alone does not define compatibility. |
| Operating and acceptance data | Use the equipment manufacturer specification for pressure and cycling. Confirm the selected part weight; 68-80 g is the old reference range. |
