High-Quality Rubber Water Pump Membrane for Industrial Use
This NBR water-pump membrane is specified by the original component reference, drawing and actual pump assembly. The existing model list below helps identify a replacement inquiry; confirm dimensions and revision before ordering. The complete assembly and supplied compound determine suitability for the planned fluid and operating duty.
Product Overview: Nitrile Rubber (NBR) Membrane
Nitrile rubber (NBR) is the existing material family. Specify the grade and hardness for water composition, additives, cleaning fluids and temperature. Confirm the molding process and dimensional tolerances for the approved part drawing.
Specify working stroke, cycle frequency, water chemistry and temperature, then agree the durability-test conditions and acceptance criteria for the membrane in its actual housing.
Key Features & Functions
1. Fluid Review: Supply water chemistry and any oil, fuel or cleaning-fluid exposure for compound selection; the NBR family alone does not establish compatibility.
2. Mechanical Requirements: Specify tensile, elongation and reinforcement requirements separately from assembled-pump pressure acceptance.
3. Mating Geometry: Match the clamping edge, profile and attachment details to the housing. Confirm sealing and separation requirements for the actual assembly.
4. Movement: Provide working stroke, frequency and expected duty cycles for design and test review.
5. Solids Exposure: Provide sediment, particulates and cleaning conditions for wear and maintenance review.

Available model and size
Existing model references listed for inquiry: 620080, 550190, 1800 0012 00, 1040081, 180034, 2240080, 550080, 0904.009, 1800/88 and 68/8. Provide the exact reference with the pump model, dimensioned drawing or original sample. Confirm current tooling, configuration and availability for that reference; these numbers do not establish interchangeable dimensions.
Applications: Where to Use Our Rubber Membranes
Review each pump or pressure-control assembly against its own drawing and compound specification. The following applications require separate confirmation:
1. Water Treatment: Provide treatment chemicals, concentrations and the original membrane reference.
2. Irrigation: Specify water chemistry, environmental exposure and pumping duty.
3. Chemical Processing: Review the complete fluid formulation and temperature against the supplied compound.
4. HVAC: Identify whether the required component is a pump membrane, expansion-tank diaphragm or bladder; these parts are not automatically interchangeable.
5. Automotive or Marine Equipment: Provide the pump model, original membrane reference, fluid formulation and any fuel or saltwater exposure. Match the membrane geometry and compound to that application.
Why Choose Our Rubber Water Pump Membranes?
-
Factory-Direct Manufacturing: We control the entire production process, from raw material selection to final vulcanization, ensuring competitive B2B pricing.
-
Replacement Reference: Identify the original part number and drawing to review fit. Agree labeling for the supplied component.
-
Customization: Submit drawings or samples, including reinforcement construction where required. Confirm dimensions, compound and qualification for the actual assembly.
-
Quality Control: ISO 9001 supports manufacturing processes. Agree compound, dimensional and functional inspection requirements for the order.
Frequently Asked Questions (FAQ)
Q: How is hot-water duty specified?
Provide continuous and peak temperature, duration and water chemistry. Confirm the limits of the supplied grade and complete assembly. Alternate polymers require their own fluid and duty review.
Q: What is required for drinking-water use?
Specify the destination market and applicable potable-water material approval. Confirm documentation for the actual supplied compound; NBR identification does not establish drinking-water approval.
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.

Water Pump Membrane Model References: Confirm the Exact Part
Keep the full reference exactly as marked, including spaces, dots or slashes such as 1800 0012 00, 0904.009 and 1800/88. Include photographs of both sides and the mounting edge, then supply measured profile, thickness, holes and connection dimensions against the original drawing. An abbreviated number or a similar appearance is insufficient to identify an interchangeable membrane. Confirm each reference as a separate line item when ordering multiple models.
