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 (T): 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.
Plumbing
The lowers have a 2 in. npt(f) fluid inlet and a 2 in. npt(f)
fluid outlet or a 2 in. bspp(f) and a 2 in. bspp(f) fluid out-
let.
Use 2 in. (50 mm) diameter pipe and plumbing. Install a
fluid shutoff valve (D) between each tank and the pump.
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Tri-Clamp Adapters
Tri-clamp adapters are available which allow sanitary
pipe to be connected to a pump with bspp inlet and out-
let. Refer to F
Install a 2 in. tri-clamp gasket (AA) in the groove of the
tri-clamp adapter (BB). Mate the tri-clamp adapter with
the sanitary pipe and secure with two clamps (CC), bolts
(DD), and nuts (EE). Install the bolts in opposite direc-
tions.
The hydraulic outlet on the motor is 1 in. npt. Use a
minimum 5/8 in. (16 mm) ID hydraulic return line
(S).
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.
