Priming of pump pdf download the water level drop at any time, the priming valve will open and vacuum within the air receiver will immediately restore the water level to ensure that the prime is never lost. Psf and pup Our commitment to research and development forms the basis for our advances in hydraulic machine manufacturing. If reducers are used in suction lines, they should be the eccentric type, and should be in- stalled with the flat part of the reducers uppermost to avoid creating air pockets.
Page 14 When checking alignment, disconnect the power source priming of pump pdf download ensure that the pump will remain inoperative.
A Q-VAC priming system operates automatically to establish and maintain a prime on all connected pumps. This site is like a library, Use search box in the widget to get ebook that you want.

Got it, continue to print. Valve in Closed Position When the pump is fully primed, pressure resulting from flow against the valve diaphragm com- presses the spring and closes the valve Figure 3.
Don’t show me this message again. In the unlikely event ov a priming valve fails and water begins to flood the priming system, a high water level switch, installed in the air receiver, will active the alarm circuit and shut the priming system off to prevent system damage. ANDRITZ self-priming pumps with an integrated vacuum pump prevent air from collecting priming of pump pdf download pf impeller inlet and guarantee that the pump primes well, even with high gas content or unfavorable suction pipe arrangements.
Do not operate the pump without the guard in place over the rotating parts exposed rotating parts can catch cloth- ing, fingers, or tools, causing severe in- jury to personnel. Vapor pressure within the pump can cause parts being disen- gaged to be ejected with great force.
Refer to the manual accompanying the power source before attempting to begin oper- ation. Download Now Read Online Description: Pum by the Gorman-Rupp Company In low discharge head applications less than 30 feet or 9 metersit is recommended that the by- pass priming of pump pdf download be run back to the wet well, and located 6 inches below the water level or cut-off point of the low level pump. If overheating does occur, stop the pump immedi- ately and allow it to cool before servicing it.
Pujp of Operation A Q-VAC priming system operates automatically to establish and maintain a prime on all connected pumps.
To print the manual completely, please, download it. As air is removed, and the vacuum eownload increases, the water level will rise until downloxd pump is fully flooded and the float-actuated priming valve closes.
Coupled Drives When using couplings, the axis of the power priming of pump pdf download must be aligned to the axis of the pump shaft in both the horizontal and vertical planes.
When checking alignment, disconnect the power source to ensure that the pump will remain inoperative.
