Extended Product Information
FAQs
Is this compatible with the Varipump 10000?
No, this specific front casing is engineered exclusively for the Varipump 20000 model.
Does this include the O-ring or gasket?
This product is the front casing unit; it is recommended to inspect your current gasket and replace it if it is brittle or stretched.
Why is the casing blue?
The blue casing is the standard branding color for the Evolution Aqua Varipump range to differentiate it from other pump components.
Can I replace this while the pump is underwater?
No, for safety and technical reasons, the pump must be removed from the pond and disconnected from the power source before performing any maintenance.
Will this fix a noisy pump?
If the noise is caused by a cracked or misaligned housing, replacing the casing can eliminate vibrations and noise.
Troubleshooting
Water leaking from the casing seam
Check if the O-ring is seated correctly and ensure the housing bolts are tightened evenly in a cross-pattern.
Pump is still losing pressure
Inspect the inlet area for blockages and ensure the impeller is not damaged or obstructed by debris.

Setup, Compatibility & Care
To install this part, ensure the pump is completely disconnected from the power supply. Remove the existing front casing by unscrewing the housing bolts. Before installing the new casing, inspect the rubber O-ring/gasket for any signs of wear or tearing, replacing it if necessary to maintain a watertight seal. Align the new casing carefully with the pump body, tighten the bolts in a cross-pattern to ensure even pressure, and double-check for leaks after turning the system back on. To maintain the casing, avoid allowing the pump to run dry and keep the inlet clear of large stones or heavy debris.
