Priming pump Professional
5.7 Priming pump Professional
Because centrifugal pumps are not self suction pumps, the required vacu-
um is created by an installed priming system. The priming pump is driven
by a v-belt and only has to be engaged for the priming process. The priming
pump is a manually or automatically controlled double-piston pump, which
is made of corrosion-resistant light alloy. The pistons provided with sealing
and guide rings are screwed to an unit and are operated via a ball bearing
eccentric, by means of a sliding pad. The moving parts of the pump are oil
bath lubricated. The suction and pressure valves are concentrically ar-
ranged in the valve covers.
Functionality
When the priming pump is activated the solenoid valve mounted in the suc-
tion line will be opened. The priming pump is driven over a v-belt from the
pump shaft. The rotating eccentric sets the piston in a back and forth move-
ment. Through the piston movement a vacuum (priming process) or an ex-
cess pressure (exhaust process) is produced. Rubber membranes serve as
valves, which are concentrically arranged in the valve covers. Through this
suction process the air will be sucked out from the pump and the suction
hoses and water sucked in, that the centrifugal pump will be flooded. If wa-
ter is exhausted from the priming pump, the suction line is to be closed. Clo-
sure of the suction valve takes place automatically.
Automatic priming
If water is exhausted at the priming pump, the suction line will be closed.
The magnetic clutch is deactivated, whereby the power transmission is in-
terrupted. The eccentric shaft ceases to be driven as a result and the piston
stands still - the priming process is complete. When the water column
breaks, this process will be repeated automatically when the automatic
priming is active.
