  • Page 15: Operating Instructions

    Operating Instructions WPT 480/P WPT 600/P WPT 720/P Installation • Check pump rotation. Standard rotation is clockwise unless otherwise marked. See Determining the Rotation of Pump. • Recommended operating speed is 850 to 1000 rpm. • Pump should always be mounted in a level, horizontal position on a firm, flat surface.

  • Page 16: Automatic Oil Pump

    • Cooling system: normal operating temperature is 140°F - 175°F. Maximum temperature is 200°F. • Coolant lines should be assembled as follows: a. (Cool water) From coolant source to the circulating pump to the fitting on the top of the rear endplate back to coolant source.

  • Page 17: Recommended Lubrication

    To adjust the oil rate, remove cap #P16. Under this cap you will find a jam nut #P15 and adjusting screw #P11. To adjust oil rate loosen jam nut and turn adjusting screw clockwise to reduce oil flow or counterclockwise to increase oil flow.

  • Page 18: Normal Operation For Liquid Cooled Pumps

    • Texaco Regal R.N.O. 68 Normal operation for liquid cooled pumps: 1. Check oil reservoir daily and fill as required. 2. When the pump is in operation, check the oiler to insure flow of oil to the pump. 3. Do not operate the pump faster than recommended rpm.

    replacing vanes. It’s good to always keep a spare set of vanes on hand for emergencies. Maintenance • Oil should be supplied to pump at a rate of 1 drop every 2 seconds. • Average usage of oil is approximately 1-2 qts. per 40 hours, depending on operation.

  • Page 20: Wpt Pump Cooling System

    • If the oiler is on the left, the pump shaft turns counterclockwise. WPT Pump Cooling System • Because vacuum pumps generate large amounts of heat during operation, consideration of pump cooling is very important. • If you are installing a liquid cooled pump, follow the pump manufacturers recommendations for pump cooling.

  • Page 24 Push the lock ring toward the fitting while pulling the oil line out of the fitting. 3. Remove the coolant line from the rear endplate. 4. Remove the bolts holding the water pump to the endplate and remove the water pump assembly. Make sure not to lose the pump drive tab.
  • Page 25 The WPT pumps are equipped with roller bearings, so no special pullers are required. Note the number of gaskets. Place a pan under the endplate to catch escaping www.natvac.com | 800.253.5500 WPT Series | 25...
  • Page 26 coolant. 6. Remove front oil line and shaft key. 7. Remove front bearing cover and coolant line. 8. Use a block or wood or heavy cardboard to cushion the rotor. 9. Place a mark on the front endplate and on the front of the housing for identification purposes.
  • Page 27 10. Slide the endplate off the rotor and remove the rotor from the housing. Note the number of gaskets. 11. Inspect the housing bore and renew as necessary. The pump bore new is 9.840 inches. The maximum overbore recommended is .060 inch. Thoroughly clean the housing and scrape off the old endplate gaskets.
  • Page 28 Place the cushion used earlier back into the bore and install the rotor, making sure the long end of the rotor is in the proper end of the housing. 14. Remove the bearings and seals. If your intention is to reuse the bearings, carefully drive the bearings out using a small hammer and punch.
  • Page 29 15. Install new seals and the bearings. The seals mount back to back and should be driven to the bottom of the endplate. Each bearing should be driven until it makes contact with the bottom of the endplate. The bearings are of different thicknesses, which is apparent upon inspection.
  • Page 30 16. Apply a hardening gasket sealer to the front plate and to the end of the pump housing. 17. Lubricate the front seal sleeve, seals and bearing. Slide the rotor into the housing, making sure the input shaft is protruding from the drive end of the housing.
  • Page 31 20. Raise the rotor and the endplate assembly up and install the endplate bolts. 21. Remove the cushion previously used from the housing and install the vanes. Make sure the round end is facing out of the rotor. 22. Apply sealer to the rear endplate and housing and install the proper number of gaskets on the rear of the housing.
  • Page 32 set the seal gap. Loosen the front endplate bolts and pry the front endplate while tightening the bolts. This is particularly important if you have honed or bored your housing. 24. Seat the bearings, front and rear. 25. You should now be able to turn the pump by hand.
  • Page 33 28. Install the drive tabs in the rear of the rotor and install the water pump assembly, using sealer on the gasket. Make sure the water pump drive lines up with the tabs. During this operation, you must also position the water line in the fitting at the top of the endplate.
