  • Page 3: Warnings And Safety

    Warnings & Safety Warnings & Safety Read this manual carefully before installing and using your Audex AS pump. Improper use of this product can cause personal injury and damage to property and may void the warranty. Please retain this manual for future reference and keep it readily available at the location of the unit.
  • Page 4 Warnings & Safety Installation For electrical installation recycling requirements, consult your local electricity authority and conform to all local and national regulations. Disconnect and lock out electrical power before installing, servicing, or maintaining the unit. Make sure that the unit is mechanically secure, and that it cannot roll or fall over and injure people or damage property.
  • Page 5 Warranty The Audex comprehensive global warranty is included in your sale price. Applies to Audex pumps purchased from Atlantic Pumps UK or All Pumps Argentina, or an authorized Intrax distributor. To keep your Warranty valid, please note: •...
  • Page 6 Warnings & Safety Environmental Always keep the operation, storage, and maintenance areas clean to avoid and/or discover oil and other contaminant leakages etc. Dispose appropriately of all waste, particularly if any non-biodegradable oils used. Handle and dispose of the processed liquid in compliance with all applicable environmental regulations. Clean up all spills in accordance with all applicable safety and environmental procedures Report all environmental emissions and leakages to the appropriate authorities.

  • Page 7: Prior To Use

    Prior to Use Prior to Use 1. Inspect the product a. Ensure that all items on the delivery note or packing list are present, and that no items are damaged. b. Unpack the goods and visually ensure that all parts are undamaged. Check that bolts and screws have not come loose during transit.

  • Page 8: Installation Considerations

    Audex pumps should never be stood on the base of a tank where silt or sand could build iii. Ensure that the cable has no sharp bends, is not pinched, and cannot be drawn into the pump inlet.

    Installation Preparation Installation Preparation 1. Pre-installation a. Recommended required install tools i. AC voltmeter ii. AC ammeter (non-contact CT type) iii. Insulation resistance tester iv. Spanners / wrenches v. Screwdrivers vi. Cable preparation tools as appropriate vii. Electrical panel key...

    Installation Electrical Installation Electrical 1. Electrical connection a. Preparation i. Ensure that the voltage and frequency of the supply match the requirements on the data plate. ii. Ensure that all circuit breakers and similar equipment are rated correctly, and set to the appropriate level where applicable.
  • Page 11 All cable bends should not be sharp. The cables have a minimum bending radius which is available from Audex or your local distributor if in doubt. x. The voltage drop in long cables must be taken into account. The pump rated voltage is as at the pump, not the supply end of the cable.

  • Page 12: Installation Testing

    Installation Testing Installation Testing 1. Operation – This is a general guide and location specific considerations must be taken into account to ensure safety. i. Rotation direction – Three phase pumps must have their rotation direction verified during installation. If the rotation direction is incorrect, any two of the live wires must be reversed. 1.

  • Page 13: Maintenance Routine

    Maintenance Routine Maintenance Routine 1. Routine maintenance a. Oil checks i. Remove the oil plug and take out a small amount of oil. The oil can be extracted easily by tilting the pump so that the oil plug faces downward. If the oil appears discoloured or mixed with water, a likely cause is a defective or worn mechanical seal which means that a full refurbishment is necessary before the pump next runs.

  • Page 16: Maintenance Disassembly

    Maintenance Disassembly Maintenance Disassembly Disassembly Instructions 1. Ensure that the pump has been isolated and that there is no static energy within the pump system (i.e. that the discharge is not pressurised). 2. Remove the cable gland, and internally disconnect the cable. 3.
  • Page 17 Maintenance Disassembly 6. Remove the three set screws and machined strainer studs, releasing the wear plate and corresponding shims. 7. Remove the shaft cap nut and impeller retaining nut, along with the impeller boss cap. 8. Remove the impeller, either by pulling directly by hand, or with mechanical aids. Do not under any circumstances heat the impeller.
  • Page 18 Maintenance Disassembly 9. Remove the impeller key from the keyway on the shaft. 10. Unfasten the volute set screws starting from the bottom of the volute and working upwards (on some models there are set screws from the volute to the casing, as well as from the casing to the volute). 11.
  • Page 19 Maintenance Disassembly 13. Remove the fixings holding the oil chamber in place, and carefully take off the empty oil chamber. It is important that this part remains perpendicular to the shaft, avoiding contact with the shaft itself. This is to prevent damage to the lower stationary mechanical seal hard wearing face.
  • Page 20 Maintenance Disassembly 18. Remove the upper rotating mechanical seal face. 19. Unfasten the bearing plate (cap head or set screws). 20. Gently remove the rotor from the stator, along with the bearing housing, and both upper and lower bearings. 21. Remove the fixings from the lower bearing retention plate, which holds the lower bearing(s) into the bearing housing.
  • Page 21 Maintenance Disassembly 22. Remove the bearing housing from the lower bearing(s) using mechanical aids if necessary. 23. Take out the oil (lip) seal from the bearing housing, where present. 24. Remove the upper stationary mechanical seal face. 25. In order to remove the lower bearing(s) from the shaft, remove the bearing locknut if present, then using head to gently expand the inner races, slide the bearing(s) off the shaft.

  • Page 22: Maintenance Assembly

    Maintenance Assembly Maintenance Assembly Assembly Instructions 1. With the pump casing upright, place the stator housing o-ring onto the upper cover and the discharge gasket around the discharge. 2. Take the upper casing and feed the stator cables through the gland hole. 3.
  • Page 23 Maintenance Assembly 13. Insert the oil (lip) seal into the bearing housing where present. 14. Place the lower bearing housing over the lower bearing(s) and screw the retention plate to the bearing housing to secure the assembly. 15. Insert the rotor into the stator, along with the bearing housing, and both upper and lower bearings. 16.
  • Page 24 Maintenance Assembly 19. Where present, put the oil (lip) seal into the oil chamber. 20. Insert the lower stationary mechanical seal face into the oil chamber, followed by the lower seal retaining plate and screw this on. 21. Place the oil chamber o-ring seal onto the oil chamber. 22.
  • Page 25 Maintenance Assembly 25. Place the lower discharge gasket onto the pump body, using grease to hold it in place if necessary. 26. Fasten the volute to the main pump casing with set screws. 27. Insert the impeller key into the keyway on the shaft with anti-seize.
  • Page 26 Maintenance Assembly 28. Push the impeller onto the shaft with anti-seize, do not use any heat. 29. Insert the impeller boss cap, spring washer, the impeller retaining nut, and the shaft cap nut. 30. Place the wear plate shims onto the wear plate and place into the volute, fastening with three set screws (using every other tapped hole).
  • Page 27 32. Place the strainer onto the pump (and the bottom plate where present) and secure with washers and nuts. 33. Pour the recommended amount of oil into the oil chamber (or until almost full). Audex recommends biodegradable hydraulic oil. 34. Ensure the oil plug has its o-ring seal on, and insert it into the pump. Wipe up any excess oil so that any leaks will be quickly spotted.

  • Page 28: Storage

    Storage Storage Storage Instructions If your pump is not needed to for longer than one week, run it anyway for at least 10 seconds per week to ensure that the rotating elements do not cease, and the mechanical seal faces remain wetted. If your pump will not be in use for longer than one month, it is not advisable to leave it in the water.
