Hydraulic Return Line
•
Return line shutoff valve (R): isolates the motor
when servicing the system.
•
Return fluid filter (J): removes residue from the
hydraulic fluid to help keep the system running
smoothly (10 micron size).
All Pumps
Fluid Line
•
Fluid filter: with a 60 mesh (250 micron) stainless
steel element to filter particles from the fluid as it
leaves the pump.
•
Fluid drain valve (U): required in your system, to
relieve fluid pressure in the hose and gun.
•
Fluid shutoff valve (D): shuts off fluid flow.
•
Fluid pressure regulator: for more precise adjust-
ment of the fluid pressure.
•
Gun or valve: to dispense fluid.
•
Fluid line swivel: for easier gun movement.
•
Suction kit: enables the pump to draw fluid from a
container.
•
Inlet and outlet seals: prevent leakage in BSPP
models. Order 193423 for 1-1/2 in. inlet seal and
193422 for 1-1/4 in. outlet seal.
•
For Viscount I Plus motors, the hydraulic outlet
on the motor is 7/8 in., 37° flare. Use a mini-
mum 5/8 in. (16 mm) ID hydraulic return line
(J).
•
For Viscount II motors, use a minimum 22 mm
(7/8 in.) ID return line (J). The motor has a 1 in.
npt(f) hydraulic oil return fitting.
CAUTION
To avoid damage to the pump, never use the return
line shutoff valve to control the hydraulic flow. Do not
install any flow control devices on the hydraulic return
line.
