AIR DRIVEN
GAS & LIQUID PUMPS

Hidrokraft has more than 30 years of hydraulic and pneumatic engineering in the design and manufacture of pumps and systems for pressure testing and chemical injection.

Our range of liquid pumps are pneumatically driven, reciprocating plunger pumps. The pumps are ratio devices that utilise low pressure compressed air to drive a larger diameter piston, which is linearly connected to a smaller hydraulic piston. Using this ratio principal, a higher pressure can be generated.

Hidrokraft liquid pump model numbers reflect the pump's nominal pressure ratio, that is, how many times grater pressure can be generated from the air drive pressure. You need to use the ratios, along with your specific output pressure requirements to select your pump.

M Series
Air Driven Liquid Pumps
(Mini Pumps)

The M series are the smallest liquid pumps in the range,

and are sometimes known as a mini liquid pumps. The pumps are single acting, single Ø80 mm air drive units that are capable of pressures in excess of 800 bar. Their size makes them a good replacement for a hand pump or for pressure testing applications where small vessels are being tested.

S Series
Air Driven Liquid Pumps

The S series of liquid pumps are single acting,

single Ø125 mm air drive units that are capable of pressuresin excess of 1200 bar. A slightly bigger pump than the M series, the S liquid pumps deliver approximately 3 times more flow at given pressures than the M series.
