Hydraulic Fluid Control
WARNING
Always turn off the hydraulic supply side valve (K
in Fig. 1) first to avoid possible serious injury or
component damage.
The hydraulic fluid control provides pressure
regulation, flow regulation, and pump isolation. See
Fig. 1 for typical installation.
Pressure Regulation
The hydraulic fluid control reduces the hydraulic oil
pressure to the operating pressure required for the
application.
Flow Regulation
The hydraulic fluid control limits the maximum
amount of oil flow to the motor to keep the hydraulic
motor within the recommended cycle rate limit. This
prevents pump runaway. The limit on the Dyna-Star
is 60 cpm.
Pump Isolation
The hydraulic fluid control has ball valves on the
supply and return sides of the manifold. The ball
valves isolate the hydraulic fluid control and pump
for servicing without stopping the hydraulic power
supply.
Installation
Grounding
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
Pump: Use ground wire and clamp as shown to the
right.
Hydraulic Hoses and Fluid Outlet Hoses: Use only
electrically conductive hoses.
Hydraulic Power Supply and Air Compressor:
Follow manufacturer's recommendations.
Any pails used when flushing: Use only metal,
grounded pails when flushing. Make firm
metal-to-metal contact between the a metal part of
the dispense valve and the pail. Use the lowest
possible pressure.
To ground the pump, loosen the grounding lug
locknut (W) and washer (X). Insert one end of a 12 ga
(1.5 mm ) minimum ground wire (Y) into the slot in lug
(Z), and tighten the locknut securely. Connect the other
end of the wire to a true earth ground. See Fig. 2.
To order a Grounding Wire and Clamp Kit, order Part
No. 222–011.
