Installing 

Pump installing quality is affected directly on pump running and life, so installing and adjusting must be strict.

1．Foundation 、 Pipeline and Pump house

We suggest that user should invite the special designing people and unit to design foundation、pipeline and install pump.

1.1   The foundation must be firm and it can bear the vibration of pump and support pump set forever, the foundation must have the ability to bear the weight that is 1.5 times of the pump set (include motor)． Usually the pump foundation is concrete foundation with bolts hole in the foundation, while install the pump, first fix foundation bolts, then make the second pour. 

1.2 Don’ s use pump as pipe bracket, all pipes should be supported separately; the pipe should be short as possible as it can, and also reduce elbow in the pipe to avoid more loss; usually the discharge pipe is one standard larger than the outlet, among pump and pipe it should install gate valve and check valve (when head is less 20m, the valve can omit), the diameter of gate valve should be not less than the diameter of pipe, the check valve is installed between gate valve and pump .

1.3 The pump should be installed properly to have proper space for operating、 disassembling and

inspection ， also the pump house should have enough device and space for lifting; when pump is driven by motor， it will be influenced by outside environment， so the house should be ventilated， It can't be too hot or too wet. When pump is used outside， adopt outside motor.

Attention:The pump pipeline system and foundation etc. are not designed by our company， so we are not responsible for it， but we may offer some suggestion about the design and operating.

3.5 Between flange and pipe, it can't leakage gas. 

4．Installation and Calibration 

4.1

The pump suspends on foundation bolts, then use nuts and gasket to fix, ensure the foundation bolts suspend in obligated hole in pedestal freely. Between pump pedestal and foundation, use couple wedge to adjust. Put gradienter on pedestal ， adjust level with wedges ， (less than 0.05mm/m ), tighten the nuts on foundation bolts suitably to prevent the pump moving . 
4.2 
Use cement to pour the pedestal and the hole of the foundation bolt. 
4.3
After the cement dry， examine whether the basement and the eye of the foundation bolt are loose. 

4.4
Place the pump set in the common base， prepare cooling water pipe. 
4.5 

Lift the rotor by adjusting the top of thrust bearing or adjusting nut in pump coupling， the lift level is 1/2 total level of the rotor , the blocking is not allowed.

4.6

Fix motor with coupling on the motor pedestal， adjust the coaxial degree of the motor and the pump by adjusting bolts.

4.7

Check the pulse of coupling, the radial pulse and end pulse of coupling of pump and motor should be less than 0.1mm. For flexible coupling, the radial deviation of pump and motor should be less than 0.1mm, the end surface clearance meets the requirement in the table and the irregularity degree along circumference should be less than 0.1mm. 

4.8 

After installing pipeline and the pump is running, check and adjust the pump concentricity again. 

4.9 
After the pump test-running for 2-3 hours， make the final check， if there is no abnormal trouble, then the installation is right.

Attention： 
1.During installing， all eyes of the hole should be covered to prevent dirty things entering the pump.

2.Ensure the rotating direction of the pump: the pump is anti-clockwise viewed from the motor end ， the incorrect rotating direction will cause the pump damaged and the

body injure.

2.2
Check the capacity and pressure of cooling water, only when it meets the requirement, pump can be started. 

2.3

When the capacity and pressure meet the requirement and more than 3 minutes, then start motor, when the pump rotates in normal speed, open the pressure meter plug and open the gate valve in the discharge pipeline gradually and adjust to needed working condition. when the gate valve on the discharge pipeline is in close, the continuous working time of the pump should not be more than 2 minutes. 
2.4

Tighten the nut on the packing cover appropriately to let liquid flow as drops, pay attention to temperature of packing box.

Attention： 
1．When the capacity and pressure meet the requirement and more than 3 minutes, then start motor, when the pump rotates in normal speed, open the pressure meter plug and open the gate valve in the discharge pipeline gradually and adjust to needed working condition. when the gate valve on the discharge pipeline is in close, the continuous working time of the pump should not be more than 2 minutes. 

2．

Don’t make too tight to packing cover, little leakage can lubricate packing but no leakage will burn packing and scratch shaft sleeve.

3． 

When pump deliver sewage, the guide bearing should have cooling lubricating water. If the capacity and pressure of cooling lubricating water is not enough, it will affect the pump’ s life severely. The water passing through the guide bearing should be kept more than 3 minutes, don’t close the cooling water until pump stops running completely. 

4． 
When deliver clean water, the guide bearing may have no cooling lubricating water, but the guard column should cancel.

3．Running 

3.1 
The temperature of bearing should be 35℃ less than outer temperature, the Max temperature should below 75℃. 
3.2 

During the running must watch the date of instrument、 the temperature of bearing、 the leakage of the packing 、 the vibration and noise of the pump, if the condition is not normal ,treat it in time. 
3.3

Make a regular check of capacity and pressure of lubricating water, the water must be kept always while pump running, also make a regular clean to the filter. 
3.4
The normal leakage in packing box is 20～30 drops per minutes. 

3.5 Pay attention to bearing temperature of the motor. 
3.6

The lubricating oil level should heap in normal level that it can't be too high or too low, when the level is too low, add the grease time, usually for first time oil should be replaced completely for running 300 hours, next time replace oil for very 3000 hours running, users can also decide it according to actual condition and past experience.

Attention： 
1．

The pump is not allowed to run when the submerged depth is not enough to prevent NPSH from damaging pump. 
2．The continuous running is not allowed when the capacity is less 30% than that of design capacity, unless add bypass pipe.

3． 

The continuous running is not allowed when the capacity is more 120% than that of design capacity otherwise it will bring NPSH and excessive power to motor. 
4．Forbid to increase the pump speed. 
5．
During pump running, if there is abnormal noise or other troubles it should be stopped to check at once.

4．Stopping 

4.1 Close plug of pressure meter. 
4.2 Shut off the outlet pipeline valve gradually.
