| Hydraulic Hand Pumps |
| Since pumps in the JHP family move the ram forward and backward in the fastest way and provide dual pressure and flow, they control dual speed automatically. High pressure, low pressure, and safety valves are installed inside. To provide large flow with low pressure, the low pressure safety valve is designed to withstand 20kg/cm2 or 30kg/cm2. When the pressure reaches this level, the pump is automatically switched to the high pressure mode and the pressure goes up to 700~1,500kg/cm2. |

| JH-2B, HAND-OPERATED PUMPS |
 |
|
| |
| This is suitable for where the ram flanger should move fast and a large amount of oil is required. With the 4-way valve, the automatic dual speed pump can be applied to any single or double acting ram with a capacity of up to 50 tons. |
| - Used in a place where JHP-2B is required to move
ram plunger more rapid and supply suggicient
volume of oil. |
| - Automatic 2-speed pump with 4way valve has been
applied for 50ton single acting and double acting ram. |

|
|
| |
| JHP-3B, HAND-OPERATED PUMPS |
 |
|
| |
| It can be used with the single acting ram where the ram flanger should move faster and a large amount if oil is required. With the 4-way valve, it can be applied to any double acting ram with a capacity of over 300 tons. |
| - When sufficient volume of oil and the highest speed
of ram plunger is required, it is manufectured to use
together with the large capacity of single acting ram. |
| - Has automatic 2-speed function. |
| - As it is mounted with 4-way valve, usable for 300ton
more double acting ram. |
