Overview
The Aqualon 12556 – Charge Pump, 165 GPH – Replaces OMAX 203745 is used in OMAX pump systems that require a 165-gallon-per-hour charge pump. It supplies steady low-pressure flow to the high-pressure pump inlet, ensuring consistent water feed during startup and normal cutting operation.
What’s Included
Charge pump assembly configured to replace OMAX 203745.
Purpose / Why It Matters
A charge pump provides the incoming water supply to the high-pressure plunger section. If the charge pump weakens or fails, the main pump may experience cavitation, pressure fluctuation, or difficulty maintaining stable operation. Replacing the unit with Aqualon 12556 restores proper inlet flow and helps protect the high-pressure components from starvation-related wear.
Compatibility
Aqualon 12556 replaces OMAX 203745 for systems that specify this OEM charge pump. No additional compatibility is claimed.
When to Replace / Service Indicators
Irregular inlet pressure
Air ingestion or cavitation at the high-pressure pump
Reduced or intermittent water flow to the pump inlet
Visible leaks or motor wear on the charge pump
Scheduled replacement during routine maintenance
Common Uses
Restoring reliable inlet water supply
Corrective replacement following charge pump failure
Preventative maintenance on high-hour pump systems
Why Choose Aqualon
Aqualon charge pumps are designed to meet the functional requirements of the OEM unit they replace. The Aqualon 12556 maintains steady inlet flow to support consistent high-pressure pump performance.
