Wanner Hydra-Cell Pro^® Pump/Motor Adapter Assembly

This article describes the parts and the order of work to put a D10-class Wanner Hydra-Cell Pro^® on a motor with an adapter, jaw coupling and Wanner^® baseplate.

Shaft Coupling

Often called a jaw coupling because of the ridged hubs. Two hubs and a plastic spider that joins them. Slide a hub onto the pump shaft and one onto the motor shaft so each shaft end is flush with the hub face.

You are not locking the two hubs together yet. The photo is only how they will sit once the adapter is in place.

Baseplate

Why make your own base plate? Wanner^® already has one for each pump model and the motors that fit it. Holes are drilled for pump and motor. Nuts are welded on the underside so every bolt is started and pulled from the top.

Bolt either the pump or the motor to the plate first — whichever has the higher shaft. That is usually the motor.

Adapter

The adapter is a cast spool that locks pump and motor shafts in line. That is what keeps the coupling from wearing and what keeps the shafts axially aligned.

1. Bolt the adapter to whichever piece is already on the base — pump or motor.
2. Please the coupling spider onto that shaft, inside the adapter bore.
3. Bring the loose piece (pump or motor) up to the adapter. Mesh its hub into the spider, then bolt that piece to the adapter.

The shorter shaft-to-grade machine — pump or motor — may hang off the adapter and never touch the plate. That is normal. The adapter is built to carry that weight and to keep the shafts lined up, so you do not experience extra vibration. A shim under the hanging foot is fine if you want both feet supported although it is not required.

This method covers F21 / F22, D03, D04, D10, D15 and H25.
