If a Walrus HQ800 pump is leaking from the bottom of the pump housing even after replacing the mechanical shaft seal, possible causes include:
1. Improper installation of the mechanical seal, such as incorrect positioning or insufficient sealing pressure.
2. Damaged or improperly installed O-rings, especially the one on the pressure tank.
3. Cracks or damage in the pump housing itself.
4. Worn or damaged impellers, sleeves, or intermediate chambers not reassembled correctly.
