   B1- Uncrating Upon receipt verify that the goods received are in exact compliance with that listed on the packing list. Check that no visible damage exists on the crate that could have occurred during transportation. Carefully remove the packaging material and check that pump and…

7. Стр. 8 B3- Storage

   If the pump is not to be installed and operated soon after arrival, store the pump in a clean, dry and frostfree place with moderate changes in ambient temperature. If the pump has regreaseable bearings, pump extra grease on bearings to prevent moisture from entering around the shaft. To…

8. Стр. 9 Fig. 2. Foundation, baseplate and fitting the shims

   Fill in the baseplate with concrete. Make no air left in it and the baseplate is well integrated with concrete foundation. Wait until the concrete firmly set (minimum 3 days). Tighten the anchor bolts. CHECK THE COUPLING ALIGNMENT AGAIN C4- Coupling Alignment a Fig. 3. Aligning a flexible…

   C5.1- General Never use the pump as an anchorage point or as a carrier for the piping. ATTENTION The pipes should be supported very near the pump (Fig. 5). It must be checked that any weight, stress or strains on the piping system should not be transmitted to the pump.…

10. Стр. 11 C5.3- Discharge piping (Fig. 6)

    A control valve should be installed in the discharge pipe, as close to the pump as possible, to regulate the required flow and head. If the total head of the pump exceeds 10 meters or if discharge line is of appreciable length a non return valve should be installed between the pump and…

13. Стр. 14 D1.3- Venting and priming

    Make sure that the pump and suction pipes are completely filled up with water. There is no problem for the pumps which have positive suction head. If there is a valve on suction line, it must be opened and air taps are loosened to enable the water replaces air in the pump, until it is completely…

14. Стр. 15

    If the pump has soft packing type stuffing boxes, these should drip during operation. The gland nuts should only be lightly tightened. In case of excessive leakage from the stuffing box tighten the gland nuts slowly and evenly until the leakage is reduced to the dripping state. Check the stuffing…

    Before starting work on the pumpset, make sure it is disconnected from the mains and can not be switched on accidentally. Follow the safety precaution measures outlined in “safety instructions”. F1- Disassembly Close all valves in the suctions and…

16. Стр. 17 F3- Shaft Seal

    F3.1- Pump with soft packing gland  While starting to change soft packing thoroughly clean the stuffing box and shaft sleeve.  Cut enough number of pieces at the suitable length diagonally from suitable size of soft packing. Roll it up over the shaft sleeve and see the ends are in full contact. …
