31 forum posts 1 photos	You are welcome to use this design of mine, no dimensions are shown but the basics are bore10mm or 3/8", stroke 32mm, ball dia 6mm or 1/4", ball seat bore 5mm, ball travel limited to 1mm by 1.5mm dia pin through body. Pump body 16mm or 5/8" dia, valve box 12mm or 1/2" dia, valve box fittings from 12mm or 1/2" hex. Eveything else can be measured from the drawing and scaled to suit your particular requirement. The main body is designed to be fabricated from whatever non-ferrous materials are available by silver soldering (Before machining) or the dimensions could be modifed to suit a casting if available. There is no O ring or gland but if required an O ring could easily be fitted in a groove turned in the ram. Cheers Deltic. Ian.
