Had a new pump installed on my, sealed gas, hot water system. I've been trying to balance the radiators. The pump has started vibrating on shut off. Is there any way of fixing this, without getting the plumber back.

I've never understood, how can you bang nails in with a water hammer?

Thats where you're going wrong. With a water hammer you don't bang the nails, you tap them.
all very entertaining, but doesn't sort my problem!
Do you mean a gentle vibration as it turns off, or a frantic tear the place apart hammering as the thing desperately pumps water that has nowhere to go ?
Freeze the water hammer :-)

Lol, now I know how to use a water hammer, thank you. :)
Sounds like your pipework is oscillating from the rotor unbalance vibration. I'd try
- Clamp the pipes firmly to the wall as close to the pump as poss
- Ditto a metre or so away as well
- Or maybe fit a better pump.
