Plumbing
Install a fluid shutoff valve (D) between the mix tank (A)
and the pump.
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing the Fluid Supply Lines, page 10.
Accessories
Install the following accessories in the configuration
shown in Typical Installation, F
. 1, using adapters as
necessary.
Hydraulic Power Supply
Be sure the power supply can provide sufficient power to
the motor. Be sure the power supply is equipped with a
suction filter to the hydraulic pump.
Hydraulic Supply Line
•
Use a minimum 7/8 in. (22 mm) ID supply line (L).
The motor has a 1 in. (25.4 mm) npt(f) hydraulic oil
supply fitting.
•
Supply line shutoff valve (S): isolates the motor
when servicing the system.
•
Hydraulic fluid pressure gauge (P): monitors the
hydraulic oil pressure to the motor to avoid
over-pressurizing the motor or lower.
•
Pressure- and temperature-compensated flow
control valve (T): prevents the motor from running
too fast, which can damage it. Pressure reducing
valve (N), which has a drain line (M) running to
the hydraulic return line (K): controls the hydraulic
pressure to the motor.
Hydraulic Return Line
•
Use a minimum 1/2 in. (13 mm) ID return line (K).
The motor has a 3/4 in. (19 mm) npt (f) hydraulic oil
return fitting.
•
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).
Fluid Line
For typical installation, see F
•
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.
NOTICE
To prevent a bellows failure:
•
Do not exceed fluid inlet pressure of 15 psi (0.1
MPa, 1.0 bar)
•
Do not use a ball check pump on the inlet side of
this pump
•
Do not use a suction tube with a check valve on
the inlet side of this pump.
NOTICE
The hydraulic power supply must be kept clean at all
times to avoid damage to the motor and hydraulic
power supply. To help keep the power supply clean:
•
Blow out hydraulic lines with air and flush thor-
oughly before connection to the motor.
•
Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.
NOTICE
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.
