VDR (13D) series uni-pump

[Features]
· An energy saving and cost effective pump.
· Features a precision built-in pressure compensating mechanism.
· Although the action of the spring means that ring movement is eccentric, increases in pressure will cause it to move to the center, setting the discharge amount to zero.
· Enables the omission of relief and unload valves in circuit configurations.
· Input will not increase in proportion to pressure, which prevents increases in oil temperature and helps make the unit smaller.
· The new design provides improved durability and low noise.
