SINGLE CYLINDER BOOSTER PUMP

This lever-operated pump was designed to charge high pressure oxygen or air cylinders to a maximum pressure of 3,000 psig (205 atm, 211 kg/sq cm) from large cylinders with pressures down to 600 psig (41atm, 42 kg/ sq cm).

It is portable – the folding handles make it easy to transport to wherever it was required. A power driven version was also available, which would have been a welcome option for those who had to pump by hand - it was very hard work!

Manufactured by Siebe Gorman Ltd, c. 1960s
