Pump NP52M, NP52M-2, NP52M-3, NP52M-2T,

Pump NP-52M, NP-52M-2, NP-52M-2T, NP-52M-3,

Designed to supply high-pressure working fluid in hydraulic ground devices.

The NP52M unit is a piston rotary pump,

having manual control of the value of maximum productivity and the value of pressure of zero productivity.

The pump allows the connection of a remote control.
