	Air-Driven Liquid Pumps General Description: A variety of TR/S hydraulic pumps are offered for various liquid output pressure up to 33,500 PSI. TR/S pumps service water, oil and most corrosive chemicals. TR/S pumps are rugged, service-proven and virtually maintenance free. The TR/S 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 TR/S 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 not 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 for bypass components and a larger reservoir.

	Standard Pump, Lubricated Model S-216-J-( ) is a general use, air-driven pump producing medium to high liquid pressures and services oil, water and compatible chemicals. The Model S-216-J standard pump is offered in nine ratios ranging from 10:1 ratio pump which develops up to 1000 PSI to the 300:1 ratio pump which develops up to 33,500 PSI. By regulating the driving air pressure, the pump's liquid output can be infinitely 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. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Standard Pump, Non-Lubricated Model S-216-JN-( ) mechanically is the same as the S-216-J. The S-216-JN-( ) pump is suitable for use in cleanrooms or laboratories. The pump uses normal shop compressed air without lubrication to actuate the pump. Its dynamic air seals are self-lubricating. The pump's exhaust air is identical to the driving air supply, thus no additional contaminants are added to the exhaust air. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Standard Pump/Reservoir, Lubricated Model S-216-JR-( ) pump assembly combines the S-216-J pump (lubricated air type) with a one gallon steel reservoir. Readily adaptable to portable power pack use or is suitable for stationary use to provide hydraulic power for production machinery or for hydrostatic testing. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Standard Pump/Reservoir, Non-Lubricated Model S-216-JRN-( ) mechanically is the same as the S-216-JR. The S-216-JN-( ) pump (non-lubricated air type) is substituted for the S-216-J pump (lubricated air type). No additional contaminants are added to the exhaust air. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Non-Contaminating Pump, Lubricated Model S-216-JS-( ) The design feature of this "JS" type pump is the mechanical separation of the liquid portion from the air-driven portion of the pump. This allows the pump to service contaminate-free fluids or fluids for human consumption. Other applications may include liquids or liquids for food processing, liquids for atomic energy use, proof testing of pressure vessels such as oxygen and nitrogen bottles, injecting corrosive inhibitors into pipe lines or for other specialized uses. The mechanical separation prevents undesirable elements or contaminates, normally present in compressed air or lubricants, from contacting the contaminate-free liquid being pumped. The separation also permits removal of the stainless steel liquid body (same body as S-216-J pump) for service or substitution with optional liquid bodies and liquid pistons to change the rated output pressure without disturbing the pump's driving side. Like the "J" type basic pump, this "JS" pump uses lubricated driving air for the air-driven portion of the pump. Mounting brackets are included as part of the pump assembly. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Non-Contaminating Pump, Non-Lubricated Model S-216-JSN-( ) This pump is suitable for clean room or laboratory use. It has the same mechanical separation features as the model "S-216-JS" pump. Additionally, the "JSN" pump uses clean, dry air; thus no contaminants are added to the pump's exhaust air. The air section of the pump has self-lubricating seals. Pump ratios are 10:1, 20:1, 30:1, 35:1, 60:1, 100:1, 150:1, 200:1 and 300:1.

	Non-Contaminating Pump for De-ionized Liquids, Lubricated Model S-216-S-( ) This non-contaminating, hydraulic pump is designed for use with mildly corrosive liquids and distilled, de-ionized or Grade A pure water. These liquids will not be contaminated by lubricated air in the driving portion of the pump. The liquid body portion of the pump contains a special, dynamic seal system which assures long service life of the pump. This seal system compensates for the low lubricity of de-ionized type liquids. Like the S-216-JS type "separated" pump, this "S" model pump offers a mechanical separation of the liquid and air-driving portions of the pump. This separation feature simplifies the removal of the liquid body for service or change without disturbing the air driving portion of the pump. Uses lubricated driving air. The "S" type separated pump is offered in three pressure ration: 35:1, 60:1 and 100:1. These ratios will produce maximum liquid outlet pressures of 4600, 6100 and 10,000 PSI respectively using 100 PSI driving air supply.

	Non-Contaminating Pump, Non-Lubricated Model S-216-SN-( ) This non-contaminating pump is suited for clean room or laboratory use. It services mildly corrosive liquids and distilled, de-ionized or Grade A pure water. Pump is the same as model S-216-S-( ) except it uses clean, dry, driving air; thus no contaminants are added to the pump's exhaust air. The air section of the pump has self-lubricating seals. Pump ratios are the same as the S-216-S pump.

	High Output Pump, Lubricated Model S-216-J-( )HO and High Output Pump, Non-Lubricated Model S-216-JN-( )HO Mechanically the same as the S-216-J-( ) or S-216-JN-( ) pumps, the S-216-( )-( )HO pumps utilize larger air passageways to dramatically increase pump speeds. Flows of up to double the standard published flow rates are available with the HIGH OUTPUT PUMPS.

	Two-Stage Hydraulic Pump, Lubricated Model S-216-HL-60 The air-driven Model S-216-HL-60 lubricated pump is a two-stage, single-acting hydraulic pump capable of first-stage flow rates of 1.95 gpm and providing second-stage discharge pressures up to 6400 PSI. Because of its high flow at low pressure and its automatic shift ability to higher pressure at lower volume, this efficient pump can rapidly attain the desired high pressure in about half the time required for a comparable single-stage pump of the same ratio. The two-stage file and discharge pressure capabilities of the pump substantially reduces the time required for hydrostatic testing or for the delivery of high pressures to production machinery for holding, clamping, forming, shearing or punching operations or for many other industrial applications. Pump wetted section materials are compatible with oil, water and corrosive liquids.

	Two-Stage Hydraulic Pump, Non-Lubricated Model S-216-HLN-60 non-lubricated pump is suitable for clean room or laboratory use. The pump is mechanically the same as "HL" pump above except for self-lubricating seals which eliminate need for air line lubrication. the pump's exhaust air is identical to the driving air supply, meaning, no contaminants have been added to the pump's exhaust air.

	These TR/S hydraulic pumps move relatively large flows of liquids at low to moderate pressures. The pumps deliver liquid with each up and down stroke of the liquid piston rather than, like other pumps, pump only with a down stroke. The pump's air-driving action is the same as the TR/S air-driving S-216-J series hydraulic pumps described above. Being air-driven, these double-acting pumps are non-arcing and non-sparking, safe for use in hazardous or confined areas.

	Double-Acting Hydraulic Pump, Lubricated Model S-216-JD-6.8 Services oil, water, liquid refrigerants, many corrosive chemicals and low lubricity liquids. With a 6.8 pumping ratio, this new, double-acting pump is well suited for liquid transfer, low pressure hydrostatic testing and other industrial uses. This pump discharges volume liquids up to 12 gallons per minute and provides for selected discharge pressures up to 680 PSI. With its liquid body and main components made from aluminum alloy and hard coated, the pump is reduced in weight and lower in cost. The standard pump's special seals in the wetted section are compatible with a wide range of chemicals while other seals in the pump are nitrile. Other seal compounds are optional. Displacement per cycle is 9.72 in³.

	Double-Acting Hydraulic Pump, Lubricated Model S-216-JD-34 Services oil, water and many corrosive liquids. With a 34 to 1 pumping ratio, this double-acting pump discharges volume liquids at any selected pressure up to 3400 PSI, suitable to many industrial applications requiring volume liquid delivery at higher pressures and holding cycles. This pump uses an internal check valve in its liquid piston head, to obtain a double-acting, steady flow of liquid. This unique design results in higher pressures and uses material resistant to many corrosive liquids. The pump has special dynamic seals to accommodate low lubricity liquids. Pump body is brass. Mounting brackets facilitate installation. Displacement per cycle is 4.90 in³.

	Double-Acting Hydraulic Pump, Lubricated Model S-216-JD-36 Services oil and non-corrosive liquids. Not for water service. Its general design is identical to the S-216-JD-34 pump described above.

The pump services water, oil and compatible chemicals. FEATURES: Has fewer moving parts and seals than comparable pumps...thus less maintenance. Safe for use in hazardous areas...no electrical connections. Pump is ideal for hydrostatic testing or water jetting applications.

	Double Ended, Single-Acting Hydraulic Pump Model S-218-GJC-( ) air-driven, double ended pump produces high pressure liquid flows up to 10.5 gallons per minute and pressures up to 6000 PSIg. It is available in two ratios: 45:1 and 60:1. The air inlet port is 1" NPT; the liquid inlet port is 1" NPT and the liquid outlet port is 1/2" NPT.

	Air-Driven Gas Pumps - General Description: TR/S pneumatic 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. Industrial applications include 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 actuating of air chucks in machine tools. Where production machinery or test setups require higher air pressure than normally provided by the shop air system, TR/S boosters can provide the extra muscle needed to operate the equipment. Because of their compact size and low cost, TR/S boosters can be combined in high-low combinations to meet higher flow and pressure requirements. (see Flo-Matix Co. Air Powered Hydraulic Power Boosters) Being air-driven and having no electrical connections, TR/S pneumatic boosters are non-sparking. These boosters can be used safely in the presence of flammable or explosive liquids or vapors. TR/s boosters and other TR/S pneumatic products are designed to a four to one minimum safety factor. HOW THE TR/S BOOSTERS WORK The TR/S gas booster is a piston-type, air-operated booster. It uses a mechanically operated, snap-action, air selector valve to cycle the booster. TR/S boosters, like TR/S 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 ration between the area of the piston, the operating air pressure and the available precharge pressure. The function of the precharge pressure to the booster is to charge the high pressure cylinder inside the booster with gas, reducing the time to return the compression piston and the air piston for the next compression cycle. The Tr/S booster works rapidly to reach the required pressure then stops at a pressure balance. The booster will hold the pressure balance indefinitely with minimal energy consumption, heat build-up or parts movement. When a pressure imbalance occurs, the booster will automatically restart to restore the pressure balance. By using a pressure regulator on the operating air supply line, the outlet gas pressure can be accurately adjusted to any pressure level between the precharge pressure and the maximum discharge pressure. With some TR/S booster models, the pumping or high pressure section is cooled with exhaust air piped from the air-driving section of the booster. In other boosters the pumping section employs external fins to dissipate the heat. Compared to other air-operated gas boosters on the market, the TR/S booster does the same job but with fewer moving parts and seals, thus less maintenance is required over its service life.

	Gas Booster Model S-86-JN-( ) A competitively priced series of versatile gas boosters are offered in six popular design ratios. These non-contaminating gas boosters are suitable for use in cleanrooms or laboratories. Since these boosters are provided with self-lubricating dynamic seals, they can be driven with normal shop air, lubricated air, or with clean dry air, depending on the application. Being air-driven, these boosters are non-sparking and safe for use in hazardous areas. Pump ratios are 2:1, 5:1, 15:1, 30:1, 60:1 and 100:1.

	Two-Stage Gas Booster Model S-218B will safely boost gasses to high pressures (up to 4,500 psig) at high flow rates (up to 20 SCFM). A series of four heat exchangers keep compressed gasses cool and coupled with specially designed TR/S seals greatly extend seal life. The S-218B booster features a sealed drive system so that the booster may be driven with natural gas from gas transmission lines (normally 200 psig). This allows the user to compress the gas up to 4,000 psig to fill bottles for vehicular use. The exhaust gas from the drive system is directed to 50 psig residential or industrial transmission lines. No gas is wasted!
