FAQs
Will this work with the Varipump 10000?
No, this set is specifically sized for the Varipump 20000 and is not compatible with other models in the range.
Do I need any special tools to install these?
Generally, you only need standard hand tools to open the pump casing, though a clean cloth and silicone lubricant are highly recommended.
How often should I replace these seals?
It is recommended to inspect them during every annual pump cleaning and replace them if they show signs of cracking, flattening, or brittleness.
Are these O-rings safe for fish?
Yes, these are genuine Evolution Aqua parts manufactured specifically for use in pond environments and are safe for aquatic life.
What if the pump still doesn't flow correctly after replacing the seals?
If flow remains poor, check the impeller for blockages or signs of wear, as the seals only handle airtightness and not mechanical propulsion.
Troubleshooting
Water continues to leak after replacement
Ensure the seating surfaces were cleaned of all debris and check that the O-ring is perfectly seated in the groove before tightening.
Pump housing is difficult to close
Verify the O-ring is the correct size for the specific groove and apply a small amount of silicone grease to help it seat properly.

Setup, Compatibility & Care
This kit is strictly compatible with the Evolution Aqua Varipump 20000. Before installation, always disconnect the pump from the electrical power supply to ensure safety. To install, unscrew the pump housing, carefully remove the old O-rings and washers, and clean the seating grooves of any debris, algae, or mineral buildup. Lightly lubricate the new O-rings with a silicone-based lubricant before seating them to ensure a smooth, long-lasting fit. When tightening the housing, do not overtighten, as this can cause the new seals to pinch or deform.
