Royal Master D-2SW-4 Hydraulic Pump Unit – Hydraulic Pump Unit
Made in Japan
Manufacturer: Royal Master
Model: D-2SW-4
Feature
These high-pressure hydraulic pump sets, which are exceptionally durable despite their small size and light weight, have an excellent track record of approximately 40 years of service in demanding applications such as hydraulic punching machines. and work in harsh conditions including civil engineering projects and foundries.
The monolithic rotor shaft shows its strength at repeated starts and stops.*
Our wet-type solenoid valve (S-D4-SGS-AHB), which has extremely low leakage, prevents leakage. heat generation and help our high-performance pumps do their job.*
For safety, the pumps have a three-position, four-way solenoid valve with 24 VAC local control circuitry.
We will install manual switch valves, pressure gauges, pressure switches and other components, and change the pump to your desired circuit.
* The 1SW-40 has a split shaft and is equipped with a dry type solenoid valve.
Technical note:
Hydraulic pumps develop the same pressure despite different sizes. The only difference is the discharge rate; Bigger ratio means you can work faster.
