1-13. CENTRIFUGAL PUMP UNIT (Continued)
PUMP - bolted to the frame assembly. Uses power from the engine to pump water from the suction
(intake) port to the discharge port. Includes a volute, impeller, check valve, and pump case with
suction (intake) and discharge ports. The volute houses the impeller which draws water in through
the suction (intake) port and forces it out of the pump through the discharge port. The check valve
prevents discharged water from running back through the suction (intake) port.
FRAME - provides a movable mounting platform for the engine and pump assemblies.
