Rugged, Service-Proven and Virtually Maintenance FreeA variety of Sprague Products hydraulic pumps is offered for various liquid output pressure up to 4300 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.

MINIPUMPS SM ( 1/3 HP ) - MEDIUM PRESSURE / LOW FLOW
Easier and lower cost maintenance– use of plastics in air drive module, unique air valve andnon bolted construction make for simple overhaul. The SM-3 has less components than competitiveproducts.No lubrication required.Water or oil options– pump can be supplied to suit oil applications or more demanding waterbased systems. Better value for money– various air valve operating modes are supplied as standard and can be readily field configured. Flexibility– manual operation option available so pump can be used as a back up to main pump orin low volume lab applications. MINI-PUMPS SM CATALOG (PDF 0.2MB) |

SERIES S-216-J ( ¾ HP ) - HIGH PRESSURE / MEDIUM FLOWfor water, oil and chemical corrosive chemicals 10 different multiple ratio max pressure: 2300 bar This general use, air driven pump produces medium to high liquid pressures and services oil, water and compatible chemicals. The Model S-216-J standard pump is offered in ten ratios (area of large air piston to area of small liquid piston) ranging fromthe 10:1 ratio pump which develops up to 1000 psi (69 bar) to the 300:1 ratio which develops up to 33,500 psi (2311 bar). By regulating the driving air pressure, the pump’s liquid output can be adjusted through its pressure range. The pump’s wetted section components are stainless steel, compatible with most non-abrasive liquids. Being air driven, the pump is safe for use in hazardous areas. |

SERIES S-216-JB-HO (1,5 - 2 HP) - HIGH PRESSURE- HIGH FLOWideal for high flow application max pressure: 2300 bar This general use, air driven pump produces medium to high liquid pressures and services oil, water and compatible chemicals. The Model S-216-J-HO standard pump is offered in six ratios ranging from the 40:1 ratio pump to the 300:1 ratio which develops up to 33,500 psi (2311 bar). By regulating the driving air pressure, the pump’s liquid output can be adjusted through its pressure range. The pump’s wetted section components are stainless steel, compatible with most non-abrasive liquids. Being air driven, the pump is safe for use in hazardous areas. CURVE PORTATES S-216-JB-HO PDF |

GAS BOOSTER FOR AIR AND NITROGENThe Gas Boosters operate on the differential piston area principle. A large area piston, driven at low airpressures, drives a small area compression piston which converts input gas to higher pressure. The output gas or dis-charge pressure is determined by the ratio between the area ofthe drive piston, the operating air pressure and the available precharge pressure supply. The function of the precharge pressure is to charge the high pressure cylinder inside the booster with gas, reducing thetime needed to reach higher pressures. In double-ended gasboosters, the precharge gas adds power to the compression stroke. POSSIBLE APPLICATIONS:
