2.8 FOOT VALVE / SUCTION TUBING
INSTALLATION
The Foot Valve acts as a check valve to keep the
pump primed in suction lift applications.
The foot valve is designed to be submersed in
the solution tank or drum and must sit in a vertical
position at the bottom. Position approximately
2 inches (50 mm) off the bottom if the tank or drum
contains sediment.
Note:
Pump models equipped with high-viscosity liquid
ends are not equipped with foot valves. Flooded
suction is recommended. A 1/2” NPT connector
is included for flooded suction installations.
The ceramic weight, when installed, positions the
foot valve in a vertical position.
1. Attach the foot valve to one end of the
suction tubing (see Tubing Connections,
Section 2.3).
2. Slide the ceramic weight over the tubing
end until it contacts the top of the foot valve
coupling nut.
3. Place foot valve and tubing into the solution
tank. Check that the foot valve is vertical and
approximately 2 inches (50 mm) from the
bottom of the tank or drum (see illustration).
Connect the other end of the tubing to the
suction side of the pump head (bottom side)
(see Tubing Connections, Section 2.3).
