SC Air Operated Liquid Pumps

1. L3 and L3C Series Liquid Pumps

These are more compact than other liquid pumps available. They are air operated with pressure capable of exceeding 18,000 psi. Wetted sections are available in stainless steel and carbon steel. They can be used with de-ionized water, nitrous oxide, and carbon dioxide. Remote pilot and hand pump options are available. 

Common applications:

General Information:

Air Drive

Require no electrical power. Powered by pressurized air, nitrogen vapor, or natural gas. The air drive psi supplied is translated to output pressure using the pressure ratio. If the pressure ratio of the pump is 20:1 and air drive pressure supplied is 50 psi, this means the output pressure is approximately 1,000 psi. A hand pump attachment option is available for precise pressure control or great for applications where shop air is not available.

L3 & L3C ratios available: 20:1, 31:1, 40:1, 55:1, 79:1, 123:1, 133:1, 213:1

• Starting air drive pressure: < 15 psi
• Max air drive pressure: 125 psi (intermittent duty)
• Max output pressure: 24,375 psi at 125 drive psi, 1.0 gpm flow rate

Operation

These pumps operate using the principle of differential areas. A small diameter hydraulic plunger is driven by an air piston and provides a pressure ratio that determines the maximum output pressure.

Cycle

When air is first supplied to the pump, the pump will cycle at maximum speed with maximum flow. It will continue to cycle automatically as the pressure increases. Only slight drops in outlet pressure or increase in air drive pressure will occur each cycle, thanks to very low frictional resistance.

Equilibrium

When the air drive force and output pressure are equal, the pump stops automatically. The pump will maintain pressure with zero energy consumption.

Media

• Plain water
• All hydraulic fluids
• Distilled and di-ionized water
• Solvents
• Mild chemicals
• Liquified CO2

Features

• 316 Stainless Steel wetted hydraulic construction

2. 10-4 Series Liquid Pumps

These are designed for high output capacity, easy maintenance, and wide ranges of operating pressures and output capacities.

Common applications:

Great for applications requiring extreme intermittent pressure, such as in water blasting.

General Information:

Air Drive

Require no electrical power. Powered by pressurized air, nitrogen vapor, or natural gas. The air
drive psi supplied is translated to output pressure using the pressure ratio. If the pressure ratio of the
pump is 30:1 and air drive pressure supplied is 50 psi, this means the output pressure is
approximately 1,500 psi. 
10-4 Series ratios available: 5:1, 10:1, 15:1, 30:1, 35:1, 55:1, 100:1, 140:1, 220:1, 300:1

•         Starting air drive pressure: < 10 psi
•         Max air drive pressure: 100 psi
•         Max output pressure: 29,500 psig at 100 drive psi
•         Volume Per Stroke: 0.047 – 2.59 in3

Modifications

     10-4 Series has one modification option available: model “A”. These use dual seals in the hydraulic assembly with a bleed-off between the seals to the atmosphere. This makes it easier to identify hydraulic seal leakage by providing a visual indication. One application for this may be where contamination of the air motor from the hydraulic fluid being pumped is undesirable.

3. 10-5 & D5 Series Liquid Pumps

     These pumps are similar to the 10-4. They may be mounted in any position, but vertical is preferred. A drain cock should be used to drain off any liquid that may accumulate in the pilot valve air chamber if mounted in another position. The D5 Series uses dry lubricant, so it does not require air lubrication. The 10-5 Series requires lubricated air.

General Information:

         4.    Volume Per Stroke: 0.048 – 5.54 in3

Modifications

Six modification options are available.

       Model “A” uses dual seals in the hydraulic assembly with a bleed-off between the seals to the atmosphere. This makes it easier to identify hydraulic seal leakage by providing a visual indication. One application for this may be where contamination of the air motor from the hydraulic fluid being pumped is undesirable.

     Model “B” have a bottom inlet connection for tank top connection or alternate mounting configuration.

      Model “C” uses PTFE chevron packing in the hydraulic assembly. This provides maximum performance when other packing material is not compatible with the media or when used in extreme temperatures. Furthermore, the modification from Model “A” is included with PTFE O-rings.

       Model “H” uses special packing in the hydraulic assembly. It provides greater life expectancy from the hydraulic seals in situations where hydraulic fluid may by contaminated. Furthermore, the modification from Model “A” is included with PTFE O-rings.

        Model “K” uses a special air piston in the air motor assembly that decreases the stroke of the  pump. This decreases the internal forces and extends the life of the air motor. Great for  applications with rapid pressure drops, such as in burst testing.

         Model “R” uses an isolator attachment that prevents the hydraulic piston from retracting into     the air motor. This eliminates the possibility of contamination through the piston. It also acts as a heat barrier.

4. 10-6 & D6 Series Liquid Pumps

      These pumps are similar to the 10-5. They may be mounted in any position, but vertical is preferred. A drain cock should be used to drain off any liquid that may accumulate in the pilot valve air chamber if mounted in another position. The D6 Series uses dry lubricant, so it does not require air lubrication. The 10-6 Series requires lubricated air.

General Information:

Air Drive

        Require no electrical power. Powered by pressurized air, nitrogen vapor, or natural gas. The air drive psi supplied is translated to output pressure using the pressure ratio.

12. SC Gas Boosters and Systems

        SC Hydraulic differentiates itself from competition with the speed to which it may custom build booster systems. Standard lead time for systems are 1-2 weeks. This can be expedited for a fee. Custom unit lead time typically runs 3-4 weeks which is less than half the time of other manufacturers. Other manufacturers will quote 6-8 weeks for a standard system.

      How is SC so much faster? Other manufacturers build many other systems. SC specializes in booster systems. They are not a large rigid company, but a medium flexible one. They work closely with each customer to satisfy their exact needs. In addition to this, SC manufactures the parts used in their units on-site. They do not depend on suppliers. Also, almost any booster they manufacture can be used in any system.

 GB Series Gas Booster Single Stage - Single Acting

      This series of gas boosters is SC’s smallest design. Great for pressurizing small volumes or pressure testing small components. The pressure chamber is hydrocarbon free. Can work with argon, helium, nitrogen, oxygen, hydrogen, and pressure as low as 50 psi. Flow can reach up to 14-SCFM.

 Ordering Information:

       First, choose the pump you need for your application. Read our above section on 10 Series   Pumps for a detailed comparison. Technical specs are provided for each 90 Series power unit below.

       The 90-4 series uses a 10-4 pump the 90-5 uses a 10-5 pump and the 90-6 series uses a 10-6 pump. Next, choose the body material, see below.

  General Information:

  Air Drive

        Require no electrical power. Powered by pressurized air, nitrogen vapor, or natural gas. The air drive psi supplied is translated to output pressure using the pressure ratio. If the pressure ratio of the pump is 10:1 and air drive pressure supplied is 50 psi, this means the output pressure is approximately 500 psi.

      Buna-Nitrile and Viton seals are available for the air motor section. Buna-Nitrile, EPR, and Fluorocarbon seals are available for the hydraulic section. Special seals may be requested if needed.

   Body Material

      Hydraulic section material can be constructed of aluminum bronze & stainless-steel alloy, or stainless steel, or cad plated carbon steel, stainless steel. Non-lubricated is standard, but lubricated is an option.

The reservoir is made of polyethylene to reduce the weight. Compatible with all L3 series standard pumps and includes air controls, shut-off, high-pressure gauge, manifold, bleed valve, and return line.

Common applications:

Ordering Information:

      First, choose the pump you need for your application. Read our above section on L3 Series Pumps for a detailed comparison. Use the ordering table below to create your power unit.

General Information:

Air Drive

         Require no electrical power. Powered by pressurized air, nitrogen vapor, or natural gas. The air drive psi supplied is translated to output pressure using the pressure ratio. If the pressure ratio of the pump is 20:1 and air drive pressure supplied is 50 psi, this means the output pressure is approximately 1,000 psi. A hand pump attachment option is available for precise pressure control or great for applications where shop air is not available.

         L3 & L3C ratios available: 20:1, 31:1, 40:1, 55:1, 79:1, 123:1, 133:1, 213:1

        1. Starting air drive pressure: < 15 psi

        2. Max air drive pressure: 125 psi (intermittent duty)

        3. Max output pressure: 24,375 psi at 125 drive psi, 1.0 gpm flow rate

Operation

      These pumps operate using the principle of differential areas. A small diameter hydraulic    plunger  is driven by an air piston and provides a pressure ratio that determines the maximum output pressure.

Cycle

       When air is first supplied to the pump, the pump will cycle at maximum speed with maximum flow. It will continue to cycle automatically as the pressure increases. Only slight drops in outlet pressure or increase in air drive pressure will occur each cycle, thanks to very low frictional resistance.

Equilibrium

         When the air drive force and output pressure are equal, the pump stops automatically. The pump will maintain pressure with zero energy consumption.
