"Partnering with industry for more than half a century "

Sprague Products offers a variety of industrial Hydraulic Pumps 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.

The Sprague Products Gas Booster, like Sprague Product air-driven hydraulic pumps, employ the piston differential areas principle - a large area air piston, driven at low air pressure to drive a small area compression piston which converts input gas to higher pressure, lower volume output gas. The booster gas output or discharge pressure developed by the compression piston is determined by the ratio between the area of the air piston, the operating air pressure and the available pre charge pressure. The function of the pre charge pressure to the booster is to charge the high pressure cylinder inside the booster with gas, reducing the time required to reach higher pressures, and the time to return the compression piston and the air piston for the next compression cycle.
