PUMP CONSTRUCTION
Little Giant tube pumps consist of a cylindrical aluminum housing that
accepts a flexible tube radially against the inside and an impeller assembly
consisting of ball bearings rotates in the cylinder. As the impeller rotates it
squeezes tubing which wil create a suction on the intake side and draw fluid
through the tubing creating a pumping action. Fluid being pumped never
touches any pump parts except for the tubing.
TUBING
Selection of proper tubing or each application is extremely important. Tubing
selected must be chemically inert to the materials being pumped. Three types
of
tubing are most commonly used. They are: rubber, Tygon R3602 and
neoprene. All 3 types are sufficiently flexible
and
can be squeezed shut and
then
rapidly regain their shape after the rollers pass over them. Tubing with the
hardness of 60 durometer gives good performance. The walI thickness for any
tubing used should be 1/8". The LG-100 series accepts 3/16" x 7/16" to 1/4" x
1/2" tubing. The LG-300 series accepts 3/8" x 5/8" to 1/2" x 3/4" tubing. Do not
use tubing with wall thickness over 1/8".
