Signs Your AR45 Valve Kit Needs Replacement
Replace worn check valves if you notice:
- Pulsing or fluctuating pressure
- Reduced flow output
- Loss of prime
- Inconsistent spraying performance
- Internal leakage or backflow
- Difficulty maintaining operating pressure
- Reduced pump efficiency
- Excessive valve wear during inspection
Worn check valves are one of the most common causes of pressure surging and inconsistent flow in AR45 diaphragm pumps.
Installation Notes
- Relieve system pressure before servicing.
- Drain and flush the pump thoroughly.
- Remove pump head assemblies according to manufacturer procedures.
- Remove worn valves and gaskets.
- Install the replacement valves and sealing components.
- Reassemble the pump according to AR specifications.
- Test for proper pressure, flow, and leak-free operation.
Important: Inspect diaphragms and other wear components during valve replacement. For pumps with significant service hours, replacing both valve and diaphragm kits during a complete rebuild may help maximize reliability and performance.
Maintenance Recommendations
- Flush chemicals from the pump after use.
- Inspect valve assemblies regularly.
- Monitor pressure and flow performance.
- Replace worn valves before complete failure occurs.
- Follow AR maintenance schedules.
- Keep suction filters clean to reduce valve wear.
