Brass Bilge Pump needs balls

[paddypro]

I have a 2 1/2" Munster & Simms bilge pump. I managed to get a spares kit via Whale pumps, [Mr Gilmore from N.I] except for the 2 rubber ball valves which I am finding impossible to acquire. Can anybody help?

Have you tried Gloucestershire Steam & Traction Engine Company for rubber balls?

I was going to suggest A J Reeves Model Engineers supplies, who also stock nitrile balls up to 5/8 in. dia.https://vault1.secured-url.com/reeves2000/shop_item.asp?sub_cat_id=223&page=5

Is your pump 2" i/d (bore) and 2.5" dia.approx across the top cap through which the plunger operates or 2.5" bore ? If former may be able to help. VITALBA
