  • Page 4: Fields Of Applications

    - Month/ year of construction Shaft speed (Rpm) TK are multistage pumps with more elements in line, and they are divided into perpendicular planes to the rotation axis. Sealing between the different elements is ensured by O-rings tightened by sturdy outer tie rods.

  • Page 5: Noise Levels

    1.3 Noise levels The following table reports the noise level produced by TK pumps running within their operating limits and installed according to the instructions given in this manual. (Average values measured at 1 meter from the pump and elaborated according to ISO curve A - standard R 1680).

  • Page 6: Transport

    TRASPORT AND STORAGE 2.1 Transport Before transportation, please perform the following checks: -Weight of pump/motor group -Overall dimensions of pump/motor group -Suitability of lifting points The pump can be dispatched in the following ways: A) Single pallet B) Wood box The pump should be transported with equipment fit for its weight and for the shape of its packing case (see side pictures).

  • Page 7: Storage

    2.3 Storage The deivered pump is generally suitable for immediate installation. STORAGE FOR A PERIOD OF LESS THAN 3 MONTHS : - Store the pump in a dry and sheltered area. - Check that ambient temperature never falls below 5°C. - It is recommended that the pump shaft is rotated at regular intervals ( every 30 days );...

  • Page 8: General Instructions

    The pump(s) should be used only for the applications specified in par. 1.2. Recommended operational limits must be strictly observed. In case of applications not specified on this manual, please contact ATURIA to check for pump suitability, installation safety and pump life. 3.2 Precautions during operation Never put your hands or any kind of object into pump openings where the shaft rotates (see side picture).

  • Page 9: Residual Risks

    3.3 Residual risks Inobservance of the safety instructions here reported or improper use of the pump may result in heavy damage to things and/or injuries to the person. Always keep to the following directions : - Don’t kick the pump - Don’t damage the pump by wrong handling - Don’t pressurize the pump beyond recommended limits - Avoid dry running, operation at lower capacity than allowed, or running with closed gate...

  • Page 10: Installation

    INSTALLATION 4.1 Installation For what concerns pump handling at the installation site, please refer to section 2.1. The pump/motor group, coupled on a single steel-sections baseplate, must be properly fastened to its concrete slab in which the foundation bolts have been previously bedded. The group should be installed on a levelled plane.

  • Page 11: Alignment

    4.2 Alignment After positioning the pump unit on the foundation and connecting the pipes, it is necessary to align it with due precision before starting. To this purpose, remove the coupling guard and measure the concentricity and the parallelism of the half coupling joints with a ruler and a thickness gauge. Place the ruler in positions 1-2-3-4 ( see below picture ) and check radial offset “a”...

  • Page 12: Startup

    5.1 Startup Before starting the pump it is necessary to fill it with water through the suited filling hole, located on suction casing. Once the pump has been primed, close delivery gate valve and start the pump for a fraction of a second to check rotation direction.

  • Page 13: Ordinary Maintenance

    MAINTENACE 6.1 Ordinary Maintenance Once started the pump, check it as frequently as possible by means of plant instruments like pressure gauges, vacuum meters and ammeters. The pump needs normally no maintenance, except a periodical check to: - Seal operation (either mechanical or packing) - Bearing operation - Periodical renew of lubricant grease in bearings PACKING SEAL...

  • Page 14: Pump Stop

    Check bearing housing temperature: it should never exceed 70°C. If this happens, check group alignment or remove bearing housing cover as the cause might be an excessive amount of grease or a failed bearing. If a danger of frost exists, drain the pump completely during idle periods by unscrewing the draining plug (see picture aside).

  • Page 15: Pump Disassembly

    DISASSEMBLY Disassembly and reassembly operation must be carried out by skilled personnel only. Before any intervention on the pump it is necessary to: - Switch the voltage off - Close pump suction and delivery gate valve - If the pump transports hot liquids let it cool at ambient temperature - Discharge pump bowl from pumped liquid through a discharge hole.
