C4- Connecting The Piping C4.1- 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. -
Page 11: C5.5- Minimum Flow
C5.5- Minimum flow If there is a possibility of the pump having to operate at zero flow (against a closed discharge valve) or near the closed valve with almost no flow, then a minimum flow valve (or a by-pass check valve) must be installed on the discharge nozzle or on the discharge piping right after the pump but before the flow regulating valve. -

Page 13: D1.3- Venting And Priming
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 full with water. -
Page 14: E- Lubrication
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 box for overheating by hand. If the gland nuts can not be tightened any further remove the old packing rings and clean the packing chamber and insert the new packing rings. -
Page 15: F- Disassembly, Repair And Reassembly
