VR Series Piston Pumps
-
No Flange Type,
apply to
Piston Pumps.
- Combining special internal designs and strict engineering
disciplines has reduced noise level to new lows in whole
pressure zones.
- Depending on variety of application needs multiple optional
unique control methods are available. It does not only reduce a
number of unnecessary hoses, pipes and control valves but also
increase efficiency and save horsepower, and cost.
- Less capacity reservoirs can be selected and applied because
of performances of low pressure loss and less head generation.
- Wide application ranges: it is very suitable for machine
tools, plastic injection moulding machines, forging machines and
other industrial machines etc..
- Mounting flanges are made to SAE A or B 2-bolt (VR15, 18,
23, 38 types) and SAE-C 2 & 4-bolt (VR50, V70 types).
