ELECTRIC HYDRAULIC PUMP

UP-40Hseries

Model：UP-40H GS-3
・Standard Tank Oil : 10 Litres

Model：UP-40H GS-7
・Standard Tank Oil : 10 Litres

Model：UP-40H GS-8
・Standard Tank Oil : 10 Litres

Low noise● LOW-NOISE pump adopting induction motor with Single-phase 100V (400W).
● By changing the wiring and the power plug, it can be changed to single phase 200V.
● Continuous operation is possible because heat from induction motor is less and less.
● A trochoid pump is adopted as a low pressure pump, and a piston pump is adopted as a high pressure pump.
● Various valves and accessories can be stacked for many applications.
● To make it easy to carry and to protect the body, the pump has a frame.
● There is a ﬁxing hole for mounting in the tank part, it is also possible to attach a caster.
