Extreme Wear Premium Blueflex FKM Accumulator Diaphragm For Hydraulic Pumps

Product Description:

A pump diaphragm is a critical flexible component typically constructed from elastomers like NBR (Nitrile Butadiene Rubber) or FKM (Fluorocarbon Rubber), or thermoplastic materials. For reference 1040081, diaphragm material choice depends on the confirmed pump or accumulator assembly and operational demands. NBR and FKM are material options to evaluate against the actual hydraulic fluid, additives, temperature and flexing duty. Other material constructions require separate review against the drawing and service conditions. Material properties directly impact lifespan—factors like tensile strength, elongation, and compatibility with pumped media are critical. Water-based media and cleaning agents should also be identified during compound selection. Any fabric or metal reinforcement must be confirmed for the supplied diaphragm construction. Review swelling, cracking and delamination seen on the removed part when specifying a replacement.

Common pump-model enquiries include AR40, AR70 and D30; confirm the applicable parts list separately. The part references below are identifiers rather than dimension measurements or confirmed interchangeable parts:

1040081 Diaphragm: Hydraulic-Fluid Duty and Assembly Identification

Identify the assembly: Supply the pump or accumulator manufacturer, model and parts-list reference. Confirm whether the diaphragm separates fluid chambers or belongs to another pump assembly before selecting the replacement profile.

Hydraulic-fluid conditions: Include the fluid grade, additives, contamination, normal and peak temperatures and cycle frequency. FKM selection requires review of the complete duty, rather than a general high-temperature description.

Drawing and sample match: Check the outer profile, sealing edge, thickness and mounting features against the removed 1040081 part. Specify any reinforcement and inspection requirements with the approved drawing.
