Frequently Asked Questions
What is a hollow-shaft motor for?
The pump headshaft runs up through the hollow motor shaft and is adjusted from the top - the standard drive for vertical turbine pumps.
Do these include a non-reverse ratchet?
Vertical hollow-shaft motors are typically supplied with a non-reverse device to stop backspin when the pump shuts off. Verify for your model.
How do I size the thrust bearing?
Match the motor's thrust rating to the pump's maximum down-thrust. We can help spec it - call (888) 203-2358.
