NON Compatible Pump Tops for VPP755 pump.

EK-D5 X-TOP CSQ – no seal contact, tried thicker o-ring and cracked the retaining collar – no wet test. Probably will work with thicker o-ring and don’t crank down “too hard” on the retaining collar screws
EK-D5 Dual TOP G1/4 CSQ – no seal contact, no attempt with alternate o-rings made.
Monsoon SAP – sealed well and wet test commenced but after running for ~2 minutes (pump vertical) noise erupted from inside the pump. Looks like contact between impeller and volute during operation, shaft kept spinning and flicked off the white retaining washer and flat washer underneath it. It is possible I did not put impeller retaining washer back on properly, but very unlikely as pump had been in operation for many hours after it was re-assembled following the photo shoot. Has run smoothly for a few hours since the “incident”.
