replacing a pump with no part number?

Weezbo

if it is old,check what the motor starter is rated at...also,the size of the pipe comming in and out of it is helpful information,...measure the length of the "Pump"body flange to flange,...maybe...a large Grunfos would be a good replacement..if it is a floor mounted Pump with no motor numbers then you will probably have to take it apart to get the length and diameter of the motor shaft ,if you cannot figure out the motor size then bump it and check the locked rotor or start amperage.there are different keys on the various pumps sometimes that is info that comes in handy....


so, all you need is caliphers , an ampmeter/ volt meterand a punch to drive out the drift key ...the rest of the tools should be in your tool bucket :) also thread gauges come in handy....best of luck ....

How to replace a pump with no part number?

Good day all,
I am going on a call tomorow to a hospital to look at replacing a hot water circulator. They called me today and said it is a B&G with no tag on the pump or motor.
I have no clue. Someone told me about this website that I may find help here. Can someone help please?

Thanks

Heres' a couple of things to do ..........

1. Post a good picture or two.
2. Take some measurements a.bearing assy b.shaft c.motor
3. Dan knows alittle about B&G, and may help
4. http://www.bellgossett.com/

Hope this helps

Get other data too

Like, motor horsepower, motor RPM, the diameter of the pipe it's connected to, the size of the flange and if they are bushed up - or down, the bearing/seal assembly part number, whether line voltage, 230 or 3 phase, the casting number on the volute, the dimensions of the flange face to flange face of the volute alone, the total length from end of motor mount to furthest point of the fattest part of the volute "bulge," The diameter of the motor output shaft, the wire gage of the motor wires, the number of bolts that holds the bearing/seal to the volute, the approximate age of the system (perhaps the circulator is original)?

You get all that, any B&G rep can nail it for you. ****, even I could nail it for you with all that info (;-o)
