Q6889 3HP & 3.5HP Two-Speed SpaQuip Maxiflow Spa Pump replacements. The older SpaQuip Maxi-flow pumps are no longer available, and have been superseded by the new SX Series pumps. May have CAT No. K48A36C47 on the label. Q6889 is obsolete and these are our replacement pumps. May have black, grey or white motors.

Notes - Important:

• This is the closest replacement for older Maxiflow pumps. Many fit in with the split nut fine-thread adaptors, but in some cases, there may need to be other changes. See pump dimensions below. Maxiflow pumps used a proprietary thread that no other pump uses. We can't stress enough that these pumps, along with the split nut fine-thread adaptor is the closest possible pump replacement. 
  
• Images of the black pumps shows the older style Maxiflow Pumps. Photos showing the split nuts and plugs pumps are the new style.
• Wet-end Head can be rotated 90-180° to various position for various installations. Scroll images to see.
• Please note dimensions in images or information.
• Fast Shipping or Pick-Up

These replacement kits come with a retrofit split-union (see photos below) to convert to the new fine thread, in addition to the standard unions, to reduce the amount of plumbing changes needed. Often there is enough flexibility in the pipework for no plumbing changes, but on occasions some minor replumbing is necessary.

See photos for comparison of old types to the new types. Note that Spa-Quip used to use "Nominal" Horsepower ratings, so the 'Named' HP was not accurate at all. Pumps labelled 3HP might actually only be 2HP motors, and so on.
