Booster pump

The booster pump has been designed to charge high pressure cylinders from low pressure cylinders with larger volumes. The medium may be compressed air or oxygen. Typically the high pressure cylinder may be charged to 3,000 psig (205 atmospheres - 211kg/cm2). The donor cylinder may contain air or oxygen at a pressure as low as 600 psig (41 atmospheres - 42kg/cm2).

The unit is a water sealed reciprocating pump and comprises a single cylinder charged with distilled water so the piston, glands and valves are all water sealed. On the upstroke of the piston a fresh charge of gas is drawn through the non return inlet valve whilst the previous charge is forced through the delivery valve {57} into the upper chamber. As the piston travels to the top of its stroke it lifts the delivery valve off its seating allowing some of the water in the upper chamber to flow down into the cylinder thus sealing the piston.
As the piston descends the delivery valve closes, sealing off the upper chamber, and the gas in the lower half of the cylinder passes through valve {61} in the piston and through the water sealing the piston.
From the upper chamber, the gas passes through the separator {84}, in which moisture in suspension is removed by condensing onto the metal filling and draining back into the pump chamber.
As well as the hand operated version there is an electric driven version operated by a 1hp single phase motor.
The weight of the hand operated version is 84 lbs (31.4 kgs)
The weight of the motor driven version is 260 lbs (97 kgs)

For our scuba diver visitors, You may have come across the modern version of this pump known as a gas recovery pump by the
name of the Haskell Pump often used on dive boats to minimise the loss of oxygen and helium thereby keeping the gas price down.
