Centrifugal Water Pump Gasket Seal
The Centrifugal Water Pump Gasket Seal is a molded part for pump housings, flanges, covers, and other fluid connections. It is used in HVAC circulation pumps, municipal drainage systems, automotive cooling pumps, and agricultural irrigation equipment handling water-based media.

Core Advantages
Pressure Resistance up to 1.6 MPa
Pressure is listed up to 1.6 MPa. At pump housings and flange joints, the compressed gasket face stays against the mating surfaces through start-up and flow changes, limiting local seepage.
Reduced Fatigue under Cyclic Loading
Changes in pump flow and pressure repeatedly load and unload the connected housing. The gasket takes this cyclic compression without quickly losing contact at the joint.
Stable Contact during Pump Vibration
Pump vibration reaches covers, flanges, and connected housings. Because the elastomer remains compressed, it can follow small joint movements and return to position during continuous operation.
Customization
Material
Food-grade silicone, EPDM, or NBR based on water quality, glycol content, mild chemical exposure, and temperature.
Hardness
50-70 Shore A within the stated product range.
Flange and Housing Geometry
Custom OD, ID, thickness, bolt pattern, contour, and molded profile can be produced from pump drawings or physical samples.
Quality Control
Before molding, the silicone, EPDM, or NBR compound is checked against the material specification. Hardness is verified when the drawing gives a defined value or range.
Contour, thickness, ID, OD, and bolt-hole position are checked because they control flange alignment and gasket compression. The sealing face is screened for flash, cuts, incomplete molding, contamination, and local surface defects.
For water, glycol, or chemical service, fluid-exposure testing is used when the drawing defines the medium, method, and acceptance limit. Identity, quantity, visible condition, and carton status are checked before shipment.
FAQ
Q: What is the MOQ for this gasket?
A: 10,000 pieces.
Q: What is the standard payment term?
A: 30% deposit and 70% balance before shipment.
Q: Can the gasket be specified for high-temperature water?
A: Yes. EPDM and silicone versions are listed for about 120°C-150°C service.
