Sprague Products boosters have been designed to convert pre-charge low gas pressures to higher gas pressures. The boosters offer a cost effective way to compress shop air or bottled gas to meet various requirements for higher pressure, lower volume air or gas.

Developed for Industrial applications including charging accumulators, inflating high pressure tires or charging shock struts from lower pressure supply sources, the transferring of gas from a supply cylinder to another container or the actuating of air chucks in machine tools. The Sprague booster can be installed as a component or can be supplied as a ready-to-use power package.

S-218-GJC-( )—This 10.5 hp, double-acting piston pump services oil, water and compatible chemicals. It is ideal for hydrostatic testing, machine operations, charging accumulators and for deep-hole applications. Offered in three pumping ratios (45:1, 65:1 and 200:1), the S-218 pump produces medium to high pressures for controlled flow or for holding pressures. By regulating the air supply, liquid outlet pressure can be infinitely adjusted throughout the pump’s pressure range. Being air-driven, the pump is safe for use in hazardous areas. It can be used in a wide variety of temperatures and in other hostile environments. The standard pump uses a lubricated driving air supply.

Other features: Pumps rapidly to desired pressure. Holds pressure indefinitely with minimal energy consumption, no increase in liquid temperature or parts movement. Automatically restarts to restore pressure balance when imbalance occurs. Liquid pumping section materials are stainless steel and chrome-plated steel, both compatible with most non-abrasive liquids. Air motor has water emitters to prevent water from collecting in humid conditions. Can be driven with wellhead gases. Can operate in freezing or hostile conditions because of anti-icing device. Safe for use in hazardous conditions because there are no electrical sparking problems or electrical connections.

S-216-J-( ) STANDARD PUMP, LUBRICATED 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 from the 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. The S-216-J standard pump requires lubricated driving air to lubricate the pump’s dynamic air seals and other internal parts within the air portion of the pump.

Increase Air Pressure by 4 to 1: Offset Your Air Pressure Needs

  • Air amplifiers are air driven and can be used to increase available air pressure by a ratio of 4:1.
  • Outlet pressure up to 500 psi (35 bar) can be easily achieved.
  • Wherever your air pressure is too low, use an air amplifier to increase local pressure.
  • Save major changes to existing systems.

Amplifier Air Differential Piston: When Greater Pressure is Required

When a compression ratio greater than 2:1 is required, an air amplifier with differential piston is used. A relatively small pressure applied to the large piston area, results in a much larger pressure generated on the smaller area at the base of the plunger.

Dividing the large area/small area gives the compression ratio. Once the required pressure is achieved, the forces on top of the piston balance with the forces on the bottom of the plunger, and the air amplifier stroke stops.

No further energy is used to maintain the required pressure.

Unique Design Features:

  • Easy installation
