WHEELEREX 46301 Hydrostatic Test Pumps

FAQs

Q: How do I maintain my pump?

A: Flush a 50/50 antifreeze/water solution through the pump after each use to lubricate internal parts and prevent freezing in cold weather. Check strainer O-Ring for cracks before every use. Regularly inspect and change engine oil following manufacturer’s recommendations.

Q: What gear oil should I use for gear reduction?

A: Use SAE 80w90 GL-5 Gear Oil and change it according to engine manual specifications.

Pressure Feed or Gravity Feed: (Preferred Methods)

1. Fill the water line (or test vessel) to be tested prior to the pump connection.
2. Connect the water supply hose to the garden hose inlet (E) connection on the pump.
3. Open the valve and turn the supply water on.
4. Purge the pump and pressure hose of all air.
5. Connect output (pressure) hose between pump (B) and water line (or vessel) being tested. (The water line or test vessel should be pre-filled with water before the test pump is attached.)
6. Turn the pump on.
7. Purge the water line (or vessel) of all air at the highest point of the system.
8. Bring the water line (or vessel) to pressure. Watch the gauge (A) while pumping. When the desired pressure is achieved, turn the isolation valve (C) to the “off” position. The engine can now be turned off. If pressure drops, there is a leak in the line.

Siphon Method

Use a clean water source

1. Fill the water line to be tested.
2. Fill the intake hose (WR PN #34550 – not supplied with pump), with water, then quickly place the hose into a bucket and turn the pump on. Continue to run the pump until you see the water coming out of the outlet hose, with little or no air mixed with it.
3. Connect the output hose to the water line. Continue on with steps 6 through 8 in the Pressure Feed Method.

Pre-Setting Your Pump

Your pump can be pre-set to a specific pressure easily by adjusting the pressure relief valve.

1. Unscrew (counterclockwise direction) the pressure relief valve knob (D) until it stops. Your pump will now be at 0 (zero) psi.
2. Add a ball valve (not supplied with a pump) to the end of the high-pressure hose.
3. Follow steps 2 through 4 from the ‘Pressure Feed Method’.
4. As water is flowing out of the high pressure hose, turn the ball valve to the off position.
5. Slowly start turning the pressure relief valve knob (D) in the clockwise direction by ¼ turn increments, until you reach the desired pressure. When the knob is turned in all the way, the maximum pressure is achieved (300psi).
6. Your test pump is now pre-set. This eliminates over-pressurizing the water line (or the vessel).

Troubleshooting Your Pump

Test pressure not being reached:

• Possible air in line (or vessel)
  • Air needs to be purged from the system.
  • Remove pump from the system and follow steps 1 through 6 of the
  • “Pre-setting Your Pump” section.
  • If using the Siphon Method and not getting pressure, try the
  • ‘Pressure Feed’ or ‘Gravity Feed Method’ to ensure water is
  • getting into the pump.
  • Check strainer O-Ring (F) for cracks.
  • Check the quick disconnect (E) and O-Ring for cracks.
• The pressure relief valve was not adjusted properly.
  • Turn the relief valve counterclockwise and watch for a change in pressure (D).

Pump Maintenance

• Pump 50/50 antifreeze/water solution through the pump after each use to lubricate the internal parts of the pump and to avoid freezing in cold weather.
• Check strainer O-Ring (F) for cracks prior to each use.
• Check and change engine oil per manufacturer specifications.
• Gear reduction SAE 80w90 GL-5 Gear Oil. Change per engine manual specifications.

• Suction Hose Wheeler Rex PN 34550

CAUTION !!!

This pump is designed for water only!!

The pump is equipped with an adjustable pressure relief valve (E), which helps protect the system from being over-pressurized. It can be preset by plugging the end of the hose. Turn the adjusting knob clockwise to increase pressure and counterclockwise to decrease

GENERAL TOOL OPERATION WARNINGS FOR ALL TOOLS-

1. Keep Guards in Place and in working order.
2. Remove the Adjusting Keys and Wrenches from the tool before turning it on.
3. Keep the Work Area Clean. Cluttered areas and benches invite accidents.
4. Avoid Dangerous Environments. Don’t use power tools in damp or wet locations. Keep the work area well-lit. Don’t expose power tools to rain.
5. If you must use an electric tool in a damp or wet location; make sure it is plugged into a circuit that is protected by a ground fault interrupt.
6. Keep Children Away. ALL VISITORS SHOULD BE KEPT AT A SAFE DISTANCE FROM THE WORK AREA.
7. Store Idle Tools in a dry, high, or locked-up place out of reach of children.
8. Don’t Force Tool. It will do a better and safer job at the rate for which it is designed.
9. Use the Right Tool. Don’t force a small tool or attachment to do the job of a heavy-duty tool.
10. Wear Proper Apparel. No loose clothing or jewelry to get caught in moving parts. Rubber gloves and footwear are recommended when working outdoors.
11. Use Safety Glasses.
12. Don’t Abuse Cord. Never carry the tool by cord or yank it to disconnect it from the receptacle. Keep cord from heat, oil, and sharp edges.
13. Secure Work. Use clamps or vise to hold work when practical. It’s safer than using your hand and it frees both hands to operate the tool.
14. Don’t Overreach. Keep proper footing and balance at all times.
15. Maintain Tools Properly. Keep tools sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories. Equipment operators must have proper maintenance & instruction sheets. Be sure the tool operator reads and understands this information. If you don’t have current maintenance and instruction sheets, contact the factory & we will supply them at no charge.
16. Disconnect Tools when not in use; before servicing; and when changing accessories such as dies, cutters, etc.
17. Avoid Accidental Starting. Don’t carry a plugged-in tool with a finger on the switch. Be sure the switch is off when plugging in.
18. Outdoor Use Extension Cords. When the tool is used outdoors, use only extension cords suitable for use outdoors and so marked.
19. Wear Ear Protection if exposed to long periods of very noisy shop operations.
20. Do not operate tools while under the influence of alcohol, drugs, or medication.
