Sprague Products air-driven hydraulic pumps benefits

A variety of Sprague Products hydraulic pumps is offered for various liquid output pressure up to 33,500 psi (2311 bar). Sprague Products pumps service water, oil and most corrosive chemicals. Sprague Products pumps are rugged, service-proven and virtually maintenance-free.

The Sprague Products positive-displacement type pump converts air inlet pressure to hydraulic output pressure. The pump uses low pressure air to act on a large area piston to produce high hydraulic pressure with a small area piston.

In operation, the Sprague Products pump reciprocates rapidly until the system liquid pressure nears the desired level, then slows to a stop when the liquid pressure equals or balances the air pressure. This liquid-air pressure balance is maintained indefinitely in a holding condition with minimal energy consumption and with no increase in fluid temperature or parts movement.

In contrast, a motor-driven pump in a holding condition must continue to operate to maintain a pressure level. Excess liquid must be bypassed or recirculated back to the reservoir, resulting in energy-loss, heat build-up, and the need to bypass components and a larger reservoir.

The Sprague Products pump is efficient in operation and simple in design, providing the user with cost-effective and energy-saving benefits for many industrial and research applications when compared to other types of hydraulic pumps.

Hydrostatic testing

The Sprague Products air-driven pump offers economical advantages for the pressure testing of hoses, pipes, valves, fittings and other hydraulic vessels and products. The time-saving and performance advantages offered by Sprague Products pumps allow routine production testing to be converted from tedious hand-pump methods to automatic and precision testing methods.

Production machinery

The Sprague Products air-driven pump delivers high pressure liquids required by production machinery for holding, clamping, forming, shearing, punching, etc. Example of application is a hydraulic press where long holding cycles are necessary or where the work stroke is short and a high force is required. High and low volume Sprague Products pumps can be combined to produce a combination of high speed and high force at low cost.

Eliminates central power source

Because Sprague Products air-driven pumps are relatively small, they can be installed directly on individual machines or test equipment in several or separate locations as direct power sources. Pumps so mounted eliminate need for a central power system, long plumbing runs and excess hydraulic power capacity.

Safe operation

Unlike motor-driven pumps, Sprague Products air-driven pumps are non-arcing and non-sparking, and can be used safely in hazardous or confined areas.

Simpler design

Sprague Products pumps do the same job as other air-driven pumps but with fewer parts and seals, and therefore less maintenance.
