Voltmaster Centrifugal Trash Pumps
3.2.1 Priming time
At sea level, with a suction lift from 5 to 10 feet (1.5 to 3 meters), the
pump should discharge fluid in less than 1minute. A suction lift of
up 25 feet (7.6m) requires less than 2 minutes.
Priming time will increase with increased elevation above sea level.
To reduce priming time, the engine speed may be increased (after
the engine is properly broken in; see engine documentation).
If fluid is not flowing within the time specified above, shut off the
pump and check plumbing to determine whether the flow line is
the problem. See Section 4, Troubleshooting.
3.2.2 Flow control
On high suction lifts, engine speed must be increased. On shallow
lifts or when there is little fluid to be pumped, fuel usage may be
reduced and engine life increased may be by lowering the engine
speed. Refer to the engine documentation for additional
information.
