High-pressure hydraulic devices「ROCKY MASTER」series
Electric hydraulic pump RM-A22
products

Product Overview

A pump with 1.5 times the high-pressure discharge volume compared to the RM-A15.
Suitable for cylinder drives from 200 kN to 2000 kN.
Can be used both as a hydraulic power source for tools and for continuous production equipment.

Product Features

POINT

High and low pressure 2-stage pump improves work efficiency.

POINT

The high/low pressure switching valve (low pressure unloading valve) automatically switches the discharge volume based on the load, resulting in lower energy use.

POINT

Can be equipped with various ganged valves, so it can be used for a variety of applications.

POINT

Pressure gauges, casters, and oil coolers can be installed as options.

POINT

We can also manufacture pump units with a combination circuit in which one pump operates several actuators.

POINT

Discharge port diameters are all Rc3/8.

POINT

The power cord is 4.5 meters long.
