Summary of Contents for Vogt HAD Series

  • Page 2 The main purpose of this manual is to provide the necessary information for installation, maintenance and start-up of the VOGT HAD Series pumps. In order to increase the productivity of the equipment, it is recommended to carefully follow the instructions below.

  • Page 3: Safety Instructions

    Safety Instructions WARNING VOGT S.A. INFORMS THAT CONTINUOUS OPERATION OF CENTRIFUGAL PUMPS WHEN SUCTION AND DISCHARGE ARE BLOCKED IS POTENTIALLY DANGEROUS. EXCESS HEAT IS GENERATED WHICH VAPORIZES THE TRAPPED LIQUID. THIS CAN CAUSE AN EXPLOSION WHICH CAN BE LIFE-THREATENING. 2.2 General Warnings •...
  • Page 4 • Do not work under suspended loads. • Never change the operating conditions without the respective approval and authorization of VOGT S.A. • Check belt tension before starting up the equipment. • Prime pump before operating, to avoid solid particles settling on start-up and causing equipment jamming.

  • Page 5: Pump Identification

    Pump Identification 3.1 Pump Identification Codes Each VOGT Pump has a nameplate on the base where the Pump model is identified. Each digit or letter of the equipment code refers to the following: A. Suction diameter is expressed in millimeters, e.g. 40, 50, 75, 100, etc.

  • Page 6: Transaction Information

    Transaction Information The pump performs its pumping work by means of the centrifugal rotary action of the impeller rotating inside the casing and for everything to work properly the following considerations must be kept in mind: 1. Complete check of the entire pumping system prior to start-up. Piping properly aligned to the pump, valves in good condition, controls operational, pump alignment and belt tension checked, etc.

  • Page 7: Suction Conditions

    Transaction Information 4.5 Suction Conditions The suction and discharge system should be adequately insulated to ensure cleanliness and maintenance of the pump when required. The suction piping should be as short as possible and have few bends. The pipe diameter should be calculated for the minimum slurry velocity thereby reducing head losses, but keeping the velocity above the settling velocity of the solid particles.

  • Page 8: Pump Start

    Pump Start Before putting a VOGT pump into operation for the first time, the following steps should be taken: 5.1 Water System Control Seal Water System Control Seal Water pressure should be approximately 10 to 15 [psi] higher than pump discharge pressure.
  • Page 9 Pump Start Initial Start-up Next Starts Figure 2. Time compared to temperature characteristics of a grease lubricated bearing assembly The most common causes of high initial temperatures are: - Excessive grease in bearings during initial start-up due to excessive relubrication. - Belt drive tension is high for initial operation.

  • Page 10: Shutdown Procedure

    Pump Start NOTE The equipment should operate by controlling the flow, discharge pressure and motor speed mentioned within the operating curve of the equipment, based on this the pump should not work in a range less than 25% at the highest efficiency point (BEP).

  • Page 11: Pump Maintenance

    Pump Maintenance 6.1 Impeller Adjustment As mentioned above, pump efficiency and component wear rate vary as a function of the GAP between the impeller and the pump. Accordingly, the pump should have a GAP between 1 and 2 [mm] to achieve the best performance. For a pump with centrifugal seal it is recommended to double this difference, so as not to increase the seal area pressure.
  • Page 12 Pump Maintenance WARNING Table 2 is referential, field judgment during operation is essential. Normal operating conditions include: • Clean environment. • Pumps covered or protected from the weather (rain, snow, ice, dust, etc.). • Normal ambient temperatures (0 - 35°C). •...
  • Page 13 Pump Maintenance 6.4 Lubricants - Oil The oil used in all oil lubricated bearing assemblies should be as specified in this item. Oils with viscosities higher than recommended are likely to cause excessive churning and heat generation in the bearing assembly. Oil lubricated bearing assemblies should operate partially submerged.
  • Page 14 Pump Maintenance The grease that escapes outward along with the centrifugal effect when the pump is running keeps the labyrinth purged of grit and moisture. To improve purging, particularly at the wet end of the bearing assembly, replace the standard labyrinth grease purge nipple with an automatic grease feeder system (three-month capacity on smaller bearings and one-month capacity on larger ones).
  • Page 15 Pump Maintenance 6.6 Recommended Lubricants • Shell Omala 150 or equivalent. • Grease (to purge grease from the labyrinth). - For general applications: Mobil HP or equivalent. - When water splashing is likely: Shell Calinthia T or equivalent.

  • Page 16: Parts And Assembly

    Parts and Assembly 7.1 Wear Components The service life of wear parts, such as impellers and liners, varies with the pump and installation. If the pump performance drops, the replacement of wear components or adjustment of the impeller setting should be evaluated depending on their condition.
  • Page 17 Parts and Assembly 7.2 Lubricating Grease Retainers and Tapered Bearings Assembly (fig. 5) · Apply oil or light grease to the flat surfaces of the bearing and shaft. · Slide a LUBRICATING GREASE RETAINER. · The tapered bearing is installed with the larger diameter against the retainer installed in step 2. To preheat the bearing it is recommended not to exceed 120°C.
  • Page 18 Parts and Assembly The cover of the bearing holder is symmetrical and the lid can be placed at either end. The small diameter of the cap should face the front. For single row tapered bearings, the caps and cones are non-matching and can be interchanged. Assembly will be easier if you hold the cover vertically.
  • Page 19 Parts and Assembly 7.7 Axial clearance check Once the bearing carrier cover on the drive side has been moved as shown in Figure 8 and all bolts have been tightened properly, it is necessary to measure the actual axial play in the bearing carrier. Table 8.
