Overview
The Aqualon 11777 – Minor Maintenance Kit – Replaces OMAX 302700 provides the complete set of service parts required to perform a minor wet-end rebuild across all three cylinders of legacy OMAX direct-drive pumps. Matching the OEM structure of OMAX 302700, this kit replaces the routine wear components responsible for sealing integrity, check-valve support, and pressure stability within the wet end. Installing Aqualon 11777 helps restore consistent pressure rise, stabilises cutting performance, and prevents internal leakage that can lead to premature wear of high-value components.

Purpose / Why It Matters
Minor wet-end rebuilds replace the core sealing and check-valve support components that degrade through regular high-pressure cycling. The parts in Aqualon 11777 correspond directly to the elements identified for routine service in OMAX 302700, helping maintain proper sealing performance in each cylinder, stabilising check-valve behaviour, and supporting consistent pressure delivery to the cutting head.
Compatibility
Aqualon 11777 replaces OMAX 302700 and is intended for legacy OMAX direct-drive pumps that specify this OEM minor maintenance kit for three-cylinder wet-end service. No other compatibility claims are made.
When to Replace / Service Indicators
Slow or uneven pressure build
Pressure drift during cutting
Inconsistent pierce or kerf behaviour
Visible wear on seals or check-valve interfaces
Scheduled minor service intervals recommended for OMAX pumps
Common Uses
Three-cylinder minor wet-end service
Restoring pressure consistency on older OMAX systems
Preventing internal bypass leakage
Routine maintenance before high-duty production work
Why Choose Aqualon
Aqualon parts are manufactured to match the functional requirements of the OEM components they replace, offering stable sealing, reliable check-valve performance, and consistent operation within high-pressure wet-end assemblies. This provides a dependable, cost-effective option for maintaining older OMAX direct-drive pump systems.
