It's just the rubber washer in the head that wears with constant use. Inner tubes with threaded valve stems are rougher on the washer, although a bit of soapy water on the rubber before use, does help. My SKS rennkompressor has spare washers for both the push-on and MVA heads available. Any decent make of track pump should provide spare washers as well.
Is it possible for a track pump to wear out?

My Zefal pump is at least 25 years old. I've replaced the head washer a couple of times but the thing is still working just fine.
Weighs a ton being made of some semi precious metal; plod will probably call it an offensive weapon if I carry it in the street.

I ordered a new pump from Sigma sports yesterday, in fact its just arrived. Its a Bontrager one as the similar priced joe blow was out of stock and apparently the Bontrager has spare parts!
I've removed the head from the original pump and its shown below. I can't see how it comes apart but, if anyone can direct me to a replacement head, that would be great as the rest of the pump is brilliant and it would be a shame to throw it away.

I would guess that most hoses have similar inside and outside diameters and are made of rubber, so any make of head would probably fit your hose. I'm guessing that you mainly use Presta valves, so the SKS push-on head would work well for you. If you like it, get some spare washers. SJS are selling it for £5 at the moment.

Great, I'll grab a couple of heads/washers and and put them in the spares tin.
I have to admit, this thread's been an eye opener as I thought that if a pump for any reason does not work, then its a case of buy a new one. Quite nice to see that replacement heads are available at reasonable prices.

This is the one I bought for my Joe Blow, and the hose attachment looks the same as your old pump.... (but check first that the thread is the same size. I would bet that it is a standard thing).

The older I get, the faster I used to be ...
- at a price! Usually it's just the rubber washer you need - cut off the pump head and replace with a Topeak Super Chuck, and use inner tubes with smooth valve barrels

That's why morphs are a good idea. No problems pumping with those.
Nowadays rubber isn't the rubber from some decades ago anymore.
I have some pumps as old as me, from my father, the seals are still like they were back then.
The ones I bought in bike shops the last decade, they all wore out, inner pump head parts broke, with the eco friendly / certified plastic alike rotting away.
I saved some pumps by using rubber from (electric) connection box cable entries.
Since a while, I buy pumps secondhand. Eventually that good 'ol stuff pops up here and there on flea markets etc, with sellers unaware of it, and then I show my 1 euro coin.
