The amount of force a hydraulic cylinder can generate is equal to the hydraulic pressure times the "effective area" of the cylinder.

Example 1
An RC-106 cylinder with 2.24 in2 effective area operating at 8,000 psi will generate what force?
Force = 8,000 psi x 2.24 in2 = 17,920 lbs.

Example 2
An RC-106 cylinder lifting 14,000 lbs will require what pressure?
Pressure = 14,000 lbs ÷ 2.24 in2 = 6,250 psi.

Example 3
An RC-256 cylinder is required to produce a force of 41,000 lbs.
What pressure is required?
Pressure = 41,000 lbs. ÷ 5.15 in2 = 7961 psi.

Example 4
Four RC-308 cylinders are required to produce a force of 180,000 lbs. What pressure is required?
Pressure = 180,000 lbs ÷ (4 x 6.49 in2) = 6933 psi. Remember, since four cylinders are used together, the area for one cylinder must be multiplied by the number of cylinders used.

Example 5
A CLL-2506 cylinder is going to be used with a power source that is capable of 7,500 PSI. What is the theoretical force available from that cylinder?
Force = 7,500 psi x 56.79 in2 = 425,925 lbs.

The volume of oil required for a cylinder (cylinder oil capacity) is equal to the effective area of the cylinder times the stroke.

Example 1:
An RC-158 cylinder with 3.14 in2 effective area and an 8 in stroke will require what volume of oil?
Oil Capacity = 3.14 in2 x 8 in = 25.12 in3

Example 2: An RC-5013 cylinder has an effective area of 11.05 in2 and a stroke of 13.25 in. How much oil will be required?
Oil Capacity = 11.05 in2 x 13.25 in = 146.41 in3

Example 3: An RC-10010 cylinder has an effective area of 20.63 in2 and a stroke of 10.25 in. How much oil will it require?
Oil Capacity = 20.63 in2 x 10.25 in = 211.46 in3

Example 4: Four RC-308 cylinders are being used, each with an effective area of 6.49 in2 and stroke of 8.25 in. How much oil will be required?
Oil Capacity = 6.49 in2 x 8.25 in = 53.54 in3 for one cylinder Multiply by four to obtain the required capacity: 214.17 in3

2-speed pumps deliver high oil volume at low pressure for rapid cylinder piston advance, then shift to to the high pressure, low volume stage under load.

Manual (hand or foot operated). Provides portability, can be used where electricity or shop air are not available.
Air/Hydraulic. Uses shop air or a portable air compressor.
Electric /Hydraulic. What voltage is available? Is a battery operated pump preferred?
Gasoline Engine/Hydraulic. Powers high-output pumps at remote job sites where air or electricity are unavailable.

If so, consider a battery pump.

Think about how your pump will be used. If the pump is planned for high-cycle operations, make sure that the pump description says that it can be used for extended duty or high-cycle operation.

High cycle applications may require a larger capacity oil reservoir for cooling. Also, if you are using large displacement cylinders, the reservoir capacity must be sufficient to fully extend the piston of the cylinder.

Reservoir size and pump output levels will be factors to consider.

Most pumps do not exceed 90 dBA while in operation. If you are concerned about noise levels, hand/foot operated pumps offer the quietest noise level, followed by electric, air than gasoline pumps.

Use either a hand/foot pump or air pump. If the pump must operate in a spark-free environment, let Titanply know to tell manufacturer.
