High-Quality Rubber Water Pump Membrane for Industrial Use
Our high-quality rubber water pump membrane is engineered to meet the rigorous demands of industrial fluid handling. Specifically designed for longevity and precision, this Nitrile Rubber (NBR) membrane serves as a critical sealing and pressure-regulating component in various pumping systems. Whether you are replacing a worn-out part or designing a new system, our membranes ensure leak-free performance and operational efficiency.
Product Overview: Nitrile Rubber (NBR) Membrane
The Nitrile rubber membrane is the industry standard for applications requiring resistance to oils, fuels, and common industrial chemicals. Produced through high-pressure injection molding, our membranes feature exceptional dimensional stability and flex-fatigue resistance.
As a leading manufacturer, we focus on the molecular density of the rubber compound, ensuring that each water pump diaphragm can withstand millions of cycles without losing elasticity or integrity.
Key Features & Functions
-
Superior Oil & Fuel Resistance: The high acrylonitrile content in our NBR material makes it ideal for environments exposed to hydraulic fluids, oils, and greases.
-
High Tensile Strength: Reinforced structure prevents tearing and deformation under high-pressure pulses.
-
Excellent Sealing Performance: Precision-engineered edges provide a perfect vacuum seal, preventing fluid cross-contamination.
-
Flex-Fatigue Resistance: Designed for high-frequency vibration and constant movement, extending the maintenance intervals of your pump.
-
Abrasion & Wear Resistance: Maintains its surface integrity even when handling water with minor particulates or sediment.

Frequently Asked Questions (FAQ)
Q: Is the Nitrile rubber membrane suitable for hot water applications?
A: Our NBR membranes perform optimally up to 100°C. For continuous boiling water or steam, we recommend our EPDM or Viton membrane alternatives.
Q: Can these membranes be used for drinking water?
A: We offer food-grade NBR compounds that comply with general safety standards. Please specify if your application requires FDA-compliant materials.
Q: Do you support small batch custom sizes?
A: Yes, as a professional manufacturer, we support both high-volume OEM orders and specialized custom prototypes.
