POWER PRIMER PUMP

Our POWER PRIMERS are built for fast, efficient priming in pump installations with high suction lifts or extra long suction lines. Here at Protek, we offer AC or DC units for a variety of applications, including automatic priming systems. Ideal for large, diesel-powered irrigation pumps.

AC Power Primer - PP35AC

FEATURES

The self-lubricating vanes on the Vacuum Pump make the maintenance easier.
The rugged steel and cast iron Vacuum Pump construction can handle the heaviest day.
The dual fan guard on the Vacuum Pump meet OSHA's requirements.
The clear acrylic water trap housings allow the operator to see when the priming is completed.
The DC unit and Gas motor make these primers a good choice for use in remote areas far from electricity sources.
The electric cord supplied with the AC unit is 8 feet long, so it can connect easily to your pump's power source.
The solid steel base provides a sturdy mounting platform.
The coupling guard protects against damage and personal injury.

MAINTENANCE

The Vacuum Pump requires occasional flushing. Remove the pressure gauge and run ¼ cup of flushing solvent (GAST AH225 or equivalent) through the pump. If the pump fails to produce a vacuum when it is first turned on, a brief warm-up may free the blades and restore the normal functioning. The initial inspection should be performed at 500 hours.
LUBRICATION: The automatic oiler should be refilled as needed with the proper oil. Use a high detergent automotive engine oil with a viscosity equivalent to SAE 10 or less.
AIR FILTER: Clean the air filter regularly by removing it from its holder and washing thoroughly in the solvent. Replace the dried out filters.
CONNECTIONS: Be sure all connections between primer and pump are tight.
BEARINGS: Bearing life is dependent upon pump application, proper lubrication, proper cooling, and general operating conditions.
VANES: Vane life is affected by general operating environment and such factors as pump speed, vacuum levels, and duty cycle.

OPERATION

SIDE SUCTION CENTRIFUGAL PUMP TIPS:
A small amount of water entering the chamber may cause pre-rotation of the impeller, flood the water trap, and mislead the operator into thinking the pump is primed. Pre-rotation or "pre-priming" can usually be avoided by inserting a package gland through the pump casting about ¼ the suction diameter.

DOUBLE SUCTION OR SPLIT CASE PUMP TIPS:
The priming line should be connected to both the suction channels at the highest point on the casting. Never connect the priming line to the pressure volute of the pump.

INSTALLATION

TYPICAL HOOKUP ON DIESEL-POWERED CENTRIFUGAL PUMP:

Mount the primer securely to a plate on the engine or on the centrifugal pump. The primer should be high enough to allow the water in the priming line to drain back in the centrifugal pump suction.
To save time and avoid inconvenience, position the unit to provide an easy access to all lubricators, filters, and mufflers.
Install a hand valve between the power primer and the centrifugal pump. This will shut off the flow when emptying the filter jar or water trap of any water that may enter during priming.
For fast priming, the piping to the centrifugal pump suction should be ³/8" NPT or larger.
