Hydraulic Hand Pumps
   
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.
 
JHP-1BAL, HAND-OPERATED PUMPS
simplex hydraulic hand pump
 
It can be used with the single acting ram where the ram flanger should move faster and a large amount of oil is required.
With the 4-way valve, it can be applied to any double acting ram with a capacity of over 300 tons.
- One of the most popular pumps used in the common industrial field.
- This automatic double pump has the performance to supply the large
  oil for the advance and retract of ram plunger

Though it is similar to the JHP-1A manual pump, its oil tank is bigger. The 2000CC oil tank can be applied to any single acting ram with a capacity of up to 50 tons.
- The same stucture and function as JHP-1B Bigger than storage tank of JHP-1B
- Has 2000cc ample reservior usable up to 50ton of JHP-2A any single acting ram
 
 
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-3A, HANDOPERATED PUMPS
simplex hydraulic hand pump
 
This is suitable for where the ram flanger should move faster 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 100 tons.
- Used in a place where JHP-2B is required to move ram plunger more rapid and supply sufficient volume of oil.
- Automatic 2-speed pump with 4way valve has been applied for 100ton single acting and double acting ram.
 
 
JHP-3B, HAND-OPERATED PUMPS
simplex hydraulic hand pump
 
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.
