Nitrile Or FKM Rubber Membrane For Diaphragm Pump Oil Resistant Waterproof

Nitrile or FKM Diaphragm Pump Membrane — Oil Exposure and Sealing Fit

Product Features
Specify the membrane construction from the pump part drawing, including NBR or FKM grade, thickness and any reinforcement. PTFE-faced composite membranes are separate constructions requiring approval.

Oil resistance depends on the selected NBR or FKM compound and the actual fluid. Provide oil type, additives, water contamination and cleaning chemicals for compatibility review.

Confirm pressure and pulsation duty from the complete pump specification. The membrane alone does not establish a 0-25 bar operating rating.

Operating temperature depends on the approved compound, fluid and membrane construction. Agree the continuous and peak temperatures for the selected part.

Key Benefits
Replacement service life depends on stroke, cycling, fluid exposure and installation; use the pump-maker inspection criteria.
Match the flexible profile and attachment geometry to the specified reciprocating pump.
Confirm the clamping rim, surface condition and compression allowance for the selected membrane. A waterproof description does not establish a complete pump pressure rating.
Custom geometry is reviewed from drawings or samples; confirm outside diameter, thickness, bolt pattern and central attachment.

Typical Applications
• Chemical dosing pumps
• Water treatment systems
• Food-contact enquiries require a specifically approved compound and applicable documentation
• Pharmaceutical enquiries require equipment-specific material and cleanliness approval

Manufactured under an ISO 9001 quality management system. OEM replacement membranes are specified by drawing and compound; food-contact compliance requires documentation for the selected grade.

Oil-Resistant Membrane Orders: Review Both Fluid Exposure and Clamping Fit

NBR and FKM membranes are selected by compound and pump geometry. Do not substitute one material for another solely because both are described as oil resistant. The fluid-contact face and the backing face may encounter different operating conditions.
