Who It Is For

Who Uses These Spare Parts

Maintenance teams that keep pumps in service beyond the first year, and engineers who need to replace a worn component without ordering a full pump.

Industrial plants with multiple AODD pumps where downtime is costly and spare pumps are not kept on site
OEMs that need to service pumps under warranty and want to use only factory approved parts
Maintenance engineers who prefer to rebuild a pump rather than replace it
Facilities that run pumps on a 24/7 schedule and need to plan for wear part replacement
Contractors who service pumps across multiple sites and need consistent part numbers

Metalworking And Machine Tools Chemical Processing

Problems Solved

What These Kits Solve

Every kit is designed to address the failure points that occur during normal operation and extend the life of the pump.

Air valve seal failure from dirty compressed air, solved by replacing the ceramic seals and air valve body
Diaphragm rupture from overpressure or abrasives, fixed by a new diaphragm and support plate
Check ball wear from solids or high velocity, addressed by a new ball and seat
Leak at the air inlet or exhaust, resolved by a new O-ring and seal kit
Pump losing prime due to worn fluid end seals, corrected by a full fluid section rebuild kit
Exhaust noise from a worn pilot valve, reduced by replacing the pilot and main air valve

Core Advantages

Four Features Of The Repair Kits

Model Code Specific

Each kit is built to the exact model code. The code defines the body material, port size, manifold material and elastomer type, so the kit matches the original pump.

Exploded Drawings And Part Lists

All kits come with an exploded drawing and a numbered part list. The drawing shows how the parts fit together and the list assigns a number to each component.

Wear Parts Only

The kits include only the components that wear during normal operation. This avoids overstocking and reduces the cost of a rebuild.

No Guesswork

With the part list and drawing, the technician can identify each component before disassembly and confirm the correct kit is ordered.

Range Data

Kit Contents

The contents of each repair kit are defined by the model code and the fluid end material. The kit includes all parts that are replaced during a service cycle.

Material compatibility	All parts match the body material and elastomer type of the original pump

Performance figures are transcribed from the Nuodean data sheet for this pump. Flow is measured at the pump discharge with water at ambient temperature; your duty point depends on air supply pressure, suction conditions, fluid viscosity and discharge head. Ask our engineers to confirm the duty point before you order.

Application Scenarios

Answers

Spare Parts For Diaphragm Pumps FAQ

How do I find the correct repair kit for my pump?

Use the full model code from the pump nameplate or the data sheet. The code includes the series, size, body material, manifold material and elastomer type. Send this code to us and we will confirm the kit.

Are the repair kits available in stock?

No. Each kit is built to order after the model code and quantity are confirmed. This ensures the kit matches the pump exactly and avoids mismatched parts.

Where can I find the exploded drawing and part list?

The exploded drawing and numbered part list are published on the data sheet for each pump model. They are also available for download from the product page.

Can I buy individual parts instead of a kit?

Yes, individual parts are available. But the kit is recommended for a complete rebuild. The kit ensures all parts are compatible and the correct number of each is included.

What should I keep in stock for common wear parts?

Keep one diaphragm, one set of check balls and seats, and one air valve kit for each pump model in use. These are the most frequently replaced parts.
