1.This pump is used for hydraulic torque wrench and fitted in integrated way, it is an independent
hydraulic unit that mainly consists of pump, control valve, oil reservoir, motor, meter, control-line
fitting, it has the peculiarity of small volume, light weight, simple composition, convenient operation,
high working pressure. The pump can supply oil with one high and one low oil outlet at the same
time, which could make a large quantity of oil outputting. On high pressure, the low pressure pump
will automatically let oil return through the release flow valve, which can reduce power consumption,
and the pressure of the outlet can be arbitrarily adjusted from 70 to 700 bar.
2.Hydraulic oil for this pump:46# or 32# anti-wear hydraulic oil.
3.Environmental temperature for using this pump:-10~80
℃
4.Please use Wren's high pressure hose, high pressure coupler, and so on. The maximum operation
pressure of high pressure hose for this pump is 1000Bar; please choose suitable system for it.
5.If you need to use attached hydraulic product for pump, please contact WREN's engineers.
6.Please do not use this pump around the fire.
7.Please do not adjust the pressure valve arbitrarily to avoid personal injury or equipment damage
due to high pressure.
8.Please confirm that the voltage for this pump is the same as the voltage of using on the spot.
9.You'd better use the pump indoors, please protect the pump from rain if it is used outdoors.
DESCRIPTION
1. KLW41 2 0 is three-stage pump. Pressure relief valve is asslembled in the high pressure port .the
rated pressure in the low pressure port is 5-7Mpg,And the flow is 0.8L/M under 700Bar.
2. Max operating pressure:700Bar
3. Flow:three-stage,can simultaneity use 2 torque wrenches
4. Motor:220V/50Hz
5. Environmental temperature:-10~80°C
6. Rerervoir dimension:448×428×281mm
7. Weight
（
No oil
）
:28Kg
8. Hydraulic oil:ISO VG 46# or 32#
1.When operating, do not permit anyone stand at the oil output,The oil output must connect other
components when adjusting the pressure.
2.When using, do not overpass the max operating pressure.
3.If need to check motor, please shut off the pump.
4. When working, the oil back to oil reservoir may add the pressure. If open the cover plate,
unnecessary injury and damage will happen.
5.Proihbit to operate without oil
6.Keep the clean of the pump,clean especially the oil inlet, quick couplers.
7.Suggestion: in the condition of not using the pump always, please remember to replace the
hydraulic oil
