1
Tube bends
Avoid sharp bends in the tube.
Bends in the tube must be at least four times the tubing diameter.
2
Infeed/outfeed tube
The length between container, pumphead and filling nozzle must be
as short as possible.
Ensure there are no obstructions which could reduce the fluid flow in
the tube line.
Ensure that all fluid path components are suitably rated to handle the
predicted fluid path pressure.
When using a single infeed tube, ensure that the cross sectional area
of the infeed tube is greater than the combined cross sectional area
of the tubes in the pumphead.
Ensure that the outfeed tube bore is equal to or larger than the
tubing in the pumphead. When pumping viscous fluids use tube with
a bore several times larger than the pumphead tubing.

Minimum fluid level
Position the pump at or just below the minimum level of the fluid to
be pumped. This will ensure flooded suction and maximum pumping
efficiency.
