） HD20 Original HAWE Manual Pump is now available
Manual pumps are used in working conditions and simple hydraulic stations. However, domestic manual pumps are large in size, low in pressure, and inflexible in operation. Therefore, Chengdu Yiyu Technology Co., Ltd. recommends the original German HAWE H-type, HE-type, HD-type, and DH-type manual pumps to you, which can completely solve your problems!HAWE H-type, HE-type, HD-type, DH-type manual pumps
HAWE H-type, HE-type, HD-type, DH-type manual pumpsare available in two structural forms: single-acting and double-acting. The single-acting manual pump supplies oil only in one direction of the handle movement, and the suction action occurs when the handle moves in the reverse direction. The double-acting manual pump supplies and sucks oil during the reciprocating movement of the handle. The suction side of the derivative pump can withstand a pressure of up to 150 bar. This type of manual pump can be equipped with a fixed or detachable handle and can be with or without a fuel tank. The unloading valve (P and S are connected) and/or the relief valve can expand its application range.
Pressure Pmax = 80 to 600 bar
Displacement Vmax = 4 to 78 ml per stroke.
Commonly used models of HAWE manual pumps :
H16, H20, H25, HD13, HD20, HD30, HE4, DH40, DH45
The advantage of HAWE H-type, HE-type, HD-type, and DH-type manual pumps is that both their suction valves and pressure valves have zero leakage. The suction pipe should be as short as possible, and the oil level in the fuel tank must be at the same height as or higher than the suction connection port. This can prevent the suction port of the pump from being unfilled with oil when the pump is not in operation.
A single-acting pump sucks oil when the operating handle moves in one direction and discharges the oil into the pressure pipeline when the handle moves in the other direction.
A double-acting pump discharges the same amount of oil into the pressure pipeline whether the operating handle moves forward or backward.
The operating mechanisms (handle mechanisms) of open pumps and fully enclosed pumps are different;
1. For a fully enclosed pump, its driving part is inside the casing and lubricated by oil, so it does not require maintenance.
2. For an open pump, its driving part is exposed, and regular maintenance (cleaning and lubrication) is recommended.
A double-acting pump discharges the same amount of oil into the pressure pipeline whether the operating handle moves forward or backward.
The operating mechanisms (handle mechanisms) of open pumps and fully enclosed pumps are different;
1. For a fully enclosed pump, its driving part is inside the casing and lubricated by oil, so it does not require maintenance.
2. For open pumps with their driving parts exposed, regular maintenance (cleaning and lubrication) is recommended.
* This manual pump can be equipped with a fuel tank or not.
Single-acting pumps suck oil when the operating handle moves in one direction and discharge oil into the pressure pipeline when the handle moves in the other direction. HAWE H-type, HE-type, HD-type, and DH-type manual pumps come in two structural forms: single-acting and double-acting. Single-acting manual pumps supply oil only in one direction of the handle movement, and the handle moves in the reverse direction for oil suction. Double-acting manual pumps supply and suck oil during the reciprocating movement of the handle. The suction side of the derivative pump can withstand a pressure of up to 150 bar. This type of manual pump can be equipped with a fixed handle or a detachable handle and can be with or without a fuel tank.
