Suction Lift vs Flooded Suction Applications
Suction Lift Installation
Mount the FlexFlow™ pump around the top of the solution tank, not to exceed 5 feet
from pump to bottom of tank.
Flooded Suction
This installation is recommended for very low outputs, solutions that gasify and/or high
viscosity solutions. Priming is easier and loss of prime is reduced. Failure of the pump
diaphragm or rupture of the solution tubing can cause loss of solution in the tank.

Wall Mounting
The fluid end portion (head assembly) of the pump is set up to accommodate mounting
of the pump to the chemical container, either as a flooded suction, or a suction lift.
The pump head must be kept in a vertical position for proper operation. The head can
be removed and rotated 90
position.
6.
Foot valve installation
A weight is provided to hold the tubing and foot valve in a vertical position at the
bottom of the tank. Do not allow the foot valve to lay horizontally in the chemical
container. This defeats the action of the valve and causes the pump to lose prime.
Keep suction tubing reasonably short and avoid high spots or bends.
