PRINCIPLES OF OPERATION
1-10.
HOW IT WORKS.
When the engine is running a shaft with attached fins (impeller)
turns inside the pump water chamber.
This causes water to be drawn
into the chamber thru an inlet opening (port) .
Water then is discharg-
e d t h r u a n o u t l e t o p e n i n g ( p o r t ) .
A check valve located in the suction
port keeps water from running back out of the pump when it is stopped.
