What Is an ARO Pump Rebuild Kit?
An ARO pump rebuild kit is a collection of essential replacement parts designed to restore your diaphragm pump to peak performance. Over time, components such as diaphragms, seals, and valve assemblies wear down due to constant exposure to fluid, pressure, and abrasive materials. Instead of replacing the entire pump, rebuild kits provide a cost-effective solution to extend the pump’s service life.
By using a genuine ARO pump rebuild kit, you ensure that each part is designed to the manufacturer’s specifications, maintaining performance, safety, and reliability.
What’s Included in ARO Pump Rebuild Kits?
While the exact contents depend on the pump size and model, most rebuild kits typically include:
- Diaphragms – The most critical part of the pump, available in materials such as PTFE, Santoprene, or Buna-N, depending on the application.
- O-Rings and Seals – These ensure leak-free operation and chemical compatibility.
- Valve Balls and Seats – Control fluid flow and prevent backflow.
- Air Valve Components – Parts for the pump’s air distribution system to prevent stalling.
- Gaskets – Provide tight seals between pump components.
By replacing these parts as a set, operators restore their pump’s performance while reducing the risk of unexpected failures.

Benefits of Using ARO Pump Rebuild Kits
Choosing genuine rebuild kits provides multiple advantages:
1. Cost-Effective Maintenance
Rebuilding a pump using a kit is far less expensive than replacing the entire unit.
2. Restored Performance
A rebuild kit ensures the pump returns to like-new efficiency and reliability.
3. Reduced Downtime
Having a rebuild kit on hand allows quick repairs, minimising costly production delays.
4. Extended Pump Life
Regular rebuilds protect your investment and maximise the lifespan of your ARO pumps.
5. Guaranteed Compatibility
Since rebuild kits are manufactured by ARO, every component fits perfectly and functions as intended.
When Should You Use an ARO Pump Rebuild Kit?
Signs that your pump may need a rebuild include:
- Loss of Flow or Pressure – Often caused by worn diaphragms or valve balls.
- Air Leakage – Faulty seals or O-rings may be to blame.
- Excessive Noise – Clicking or rattling sounds can signal valve issues.
- Pump Stalling – Air valve components may be worn out.
- Leaks or Spills – A clear indication diaphragms or gaskets need replacing.
In most industrial settings, pumps should be rebuilt after a certain number of operational hours or whenever key performance issues arise. MultiTorque’s team can help establish a preventative maintenance schedule for your equipment.
