Before we begin with the assembly process we need to make sure of the following things: Check all the equipment is received as per the checklist provided if not make sure you provide the required materials. Check the actual condition of the construction if it is as per the civil drawings provided. If no then make sure the required changes are made. (Pipe inlet and outlet civil work needs to be checked). Check the foundation for pump if it is as per the drawings provided.
There are 4 different types of pump rooms based on the suction and delivery. In order to place the pump-motor assembly we need to know the exact positions as shown in the table. The types are classified on the basis of the suction & delivery sides. The side across the river is called as the “opposite side”.
To get a better idea of the types the details are as follows:

First and foremost check the dimensions and verify the civil work, incase its inappropriate make the required changes. After verifying the place makes sure that there is enough space for moving the pump into the pump room.
Fig.: Pump & stand assembly.
The pump assembly is as shown in the diagram along with the pump. The ideal way of assembling is with the stand outside the pump room and lifting it inside along with the stand on to the foundation. This method is convenient as there is very less space inside the pump room to assemble. Alternative method of assembling inside the pump room can also be done. The assembly of the motor need not be done from the start as there is no requirement of using it as of yet. The motor assembly will be done in detail latter on in the electrical assembly section.

After the pump is installed we need to move ahead with the plumbing. The pump has two sides, 1.) Discharge side and 2.) The delivery side, the side coming from the river end is the suction side. The suction side has two inlets one is 200 NB and the other is 150 NB. The discharge side goes out to the delivery side on to the next chamber. The outlet has the size of 200 NB two pipes with a header of 300 NB. Let’s begin the assembly from the suction side. The important point is not to start assembly from both the sides as the required adjustments become very difficult otherwise for alignment purposes. Secondly necessary 90 Deg. From the ground needs to be maintained at all connections as the plumbing won’t be appropriate for further conditions.
The suction side assembly begins with a reducer and ends with a nozzle. We will begin the assembly in the following steps as shown in the fig. There are two types of suction assemblies according to the construction. 1.) For Pump Room -Type 1 & Type 2, the assembly is common. 2.) For Pump Room -Type 3 & Type 4, the assembly is common.

They are used to control the flow of the pump one for each delivery pipe. The butter fly valve size is for 200 NB pipe. 8.) For assembly of delivery pipe to butterfly valve 200 NB. We use M16 x 120 bolts. Each delivery pipe has 6 holes. 9.) After the delivery pipe and valve assembly comes the puddle flange assembly which we will do latter. We will not make any fixing of the puddle flange or the assembly itself as we need to keep ends open for adjustments. 10.) We will assemble and bolt the puddle flange as we require fixing the butterfly valves between the delivery pipe and puddle flange. 11.) For assembling the delivery pipe to the puddle flange with the butterfly valve we will use M16 X 120 bolts. Each flange has 8 holes. The butterfly valve is squeezed in between. 12.) With the completion of the two delivery pipes we have completed the inhouse plumbing assembly for the pump room now we need to align all the pipe inlets and outlets as per the requirement. We might have to move the assembly in order to align it properly for the puddle flange placement. We need to make sure the flanges are perpendicular to the ground. 13.) Once all pipes are determined appropriately aligned we will need to fix them with the civil structure casting at all puddle flanges.

Since a very few moving parts are involved in a pipeline, it does not require much attention. Still one should not take it for granted that he will get a trouble free operation. The valve glands, flange joints, etc. may leak; the supports and clamps may get loosen and start vibrating; the pipe may get corroded internally or externally within a very short time of its commissioning. Therefore, it is necessary that a scheduled inspection be carried out on the items which may give trouble and a logbook maintained for taking necessary preventive maintenance. For every process pipe a check list may be prepared and hung in the office of maintenance in-charge. A check list for such operation may be prepared
FREQUENCY OF INSPECTION
ITEM Pressure reducing valves Threaded and flanged joints Stop valve/isolation valve Glands: Flow control valves glands Safety valves All indoor pipes (overhead) All indoor pipes (in trenches, tunnels etc.) All outdoor pipes (overhead) All outdoor pipes (underground)
Daily once Daily once Weekly once Weekly once Weekly once Quarterly Quarterly Half-yearly Every five years or so.
The jobs carried out in connection with preventive maintenance must be recorded in log book for future reference. In a pipeline, generally maintenance of leaking valves is a major problem. Therefore, standard practices followed for replacement of gland packing or gasket of a flanged joint must be noted serially, operation-wise under a heading ‘Valve Maintenance’, ‘Replacement of gland packing in running line’; Repair of flange joints, etc. and hung in the office of maintenance in-charge for future guidance of the maintenance staff.
