Common questions about manuals, registration, and support for this brand.
Before starting, ensure all connections are secure and the pump casing is filled with water according to your model's specific owner's manual. Never run the pump dry as this may damage the seals.
First, check the power supply to ensure RCDs haven't tripped. Verify all connections are airtight and that your suction line is completely submersed. If the pump still will not run, consult the troubleshooting section of your manual or contact a certified dealer.
Standard Onga pumps are designed primarily for water. If you need to pump aggressive chemicals or other fluids, contact your pump supplier, as special pump configurations are required for these applications.
To maintain optimum performance, suction pipes should be equal to or larger than the diameter of the pump's suction port. Always consult the technical data and pipe friction tables in your specific user manual to prevent issues with pressure limitations.
