Hi Richard

I have the same thing. I am fairly sure it is a standard Henderson Mk V (5) pump and you can get the service kits and much more beside at ASAP (https://www.asap-supplies.com/whale-ak8050-service-kit-for-henderson-mk5?nosto=nosto-page-search1) and other chandleries.

Once you have it apart you might as well replace the two valves and rubber diaphragm.

Best wishes Piers
