OPERATING INSTRUCTIONS FOR NEW MONO PUMP INSTALLATIONS

  • 1. Before installing a new pump, the borehole tested capacity & borehole depth should be known to avoid pumping mud, sand or air.
  • 2. Do not run the pump dry - running the pump completely dry will cause immediate damage to the rotor stator set. Where a water film exists in the bobbin bearings priming may extend over a 2/3 minute period after which damage may be sustainable by the rubber line shaft bearings.
  • 3. Do not oil stator or bobbin bearings as these are water lubricated and oil will cause them to swell.
  • 4. The ball bearings in the discharge head are lubricated for life and need no attention.
  • 5. Make sure there is proper pump adjustment before running the pump.
  • 6. Check the gland nut regularly to ensure that a slight leak is always present as this is also water lubricated. No gland leakage, the result of an excessively tight gland will cause premature gland packing deterioration and shaft wear due to the high temperature build – up.
  • 7. Excessive gland leakage, due to an insufficiently adjusted gland will result in an unacceptable wet pump house or pump surrounding and the water will damage the bearings.
  • 8. All nuts, bolts and screws must also be regularly checked for tightness.
  • 9. To avoid pipe rust or any other substance from falling into the pump, insert a piece of tissue (toilet paper will do but not a heavy, coarse or waxed paper) into the neck of the pump.
  • 10. Ensure that the pump is running/rotates in the right direction (anti-clock wise). Incorrect rotation will result in threads being unscrewed.
  • 11. The Mono unit is the most trouble free pump we could design, keep it clean, do not overload or over speed the unit, do not over-strain the discharge head and you will enjoy many years of trouble free pumping.
