  • Page 13: Hoisting

    CombiFlexBloc 1.5.3 Hoisting When hoisting a pump or complete pump units the straps must be fixed in accordance with figure 1. When lifting a pump or a complete pump unit always use a proper and sound lifting device, approved to bear the total weight of the load! Never go underneath a load that is being lifted! If the electric motor is provided with a lifting eye, this lifting eye is intended only for the purpose of carrying out service activities to the electric motor!

  • Page 14: Ordering Parts

    Ordering parts This manual contains a survey of the spare parts recommended by SPXFLOW as well as the instructions for ordering them. A fax-order form is included in this manual. You should always state all data stamped on the type plate when ordering parts and in any other correspondence regarding the pump.

  • Page 15: General

    CombiFlexBloc 2 General Pump description The CombiFlexBloc is a range of vertical non-self-priming centrifugal pumps. The discharge and suction connection can be mounted in different positions in relation to each other. The pump is driven by e vertical flange motor with extended motor shaft. There is also a version with a IEC-standard flange motor and a stub shaft.

    CombiFlexBloc 3 Installation Safety • Read this manual carefully prior to installation and commissioning. Non-observance of these instructions can result in serious damage to the pump and this will not be covered under the terms of our guarantee. Follow the instructions given step by step. •...

  • Page 20: Piping

    Piping • The piping to the suction and delivery connections must fit exactly and must not be subject to stress during operation. • The passage of the suction pipe must be amply dimensioned. This pipe should be as short as possible and run towards the pump in such a way that no air pockets can arise.

  • Page 21: Commissioning

    CombiFlexBloc 4 Commissioning Inspection of the pump • Construction with stuffing box packing: Remove the guards (0270). Check whether the nuts (1810) have not been over tightened. If necessary, loosen these nuts and tighten them again by hand. Fit the guards (0270). •...

  • Page 22: Adjustment Of Shaft Sealing

    Adjustment of shaft sealing 4.6.1 Stuffing box packing After the pump is started, the stuffing box packing will show a certain amount of leakage. Because of the expansion of the packing fibres, this leakage will gradually decrease. Make sure that the stuffing box packing never runs dry. To prevent this, loosen the nuts (1810) to the extent that the stuffing box packing leaks by drops.

  • Page 23: Maintenance

    CombiFlexBloc 5 Maintenance Regular maintenance Regularly check the outlet pressure. No water should get into the terminal box of the electric motor when the pump room is sprayed clean! Never spray water on hot pump parts! The sudden cooling down may cause them to burst and hot water may flow out! Flawed maintenance will result in shorter lifespan, possible break down and in any event loss of warranty.

  • Page 24: Noise

    Noise If a pump starts making noise, this may point to certain problems with the pump unit. A crackling noise can indicate cavitation or excessive motor noise can indicate deterioration of the bearings. Motor Check motor specifications for start-stop frequency. Faults The pump, of which you want to determine the fault, may be hot or under pressure.

  • Page 25: Problem Solving

    CombiFlexBloc 6 Problem solving Faults in a pump installation can have various causes. The fault may not be in the pump, it may also be caused by the pipe system or the operating conditions. Firstly, always check that installation has been executed in accordance with the instructions in this manual and that the operating conditions still correspond with the specifications for which the pump was purchased.

    Disassembly and assembly Top Pull Out unit ➢ The Top Pull Out unit and the electric motor of large pumps are too heavy to be lifted by hand. Use appropriate hoisting equipment. CombiFlexBloc pumps use a Top Pull Out system. The electric motor with the lantern piece, the stuffing box cover/pump cover and the impeller can be dismantled as a whole.

  • Page 29: Replacing The Impeller And The Wear Ring

    CombiFlexBloc Replacing the impeller and the wear ring The play between the impeller and the wear ring is 0,3 mm to the diameter at delivery. In case the play has increased to 0,5-0,7 mm due to wear, the impeller and the wear ring should be replaced.

  • Page 30: Disassembling The Wear Ring

    7.5.3 Disassembling the wear ring After removing the Top Pull Out unit the wear ring can be removed. In most cases the ring has been fixed so tightly that it cannot be removed undamaged. Figure 5: Removal of wear ring. 1 Measure the thickness (d) and the width (b) of the ring, see figure 5 A.
