17 Silencer Series Booster Pump, p/n: 029-0020-83-0
Introduction
❑
As the impeller rotates, the
water moving outward in the
impeller creates reduced pres-
sure or a vacuum in the suction
eye allowing atmospheric pres-
sure to push water into the
pump impeller, replacing the
water discharged.
During operation water enters
the suction eye of the impel-
ler. The rotating impeller
vanes develop discharge pres-
sure and direct the water to the
discharge opening.
The cutwater is a wedge that
divides the water between the
volute (pump body) and the
pump discharge.
