Seal Varieties:

There are 3 seal kinds,expeller seal,packing seal and mechanical seal.
(1) Expeller Seal. Use pressure seal made by impeller and expeller in sequence,packing or lip sealing ring for shut down seal.The principal areas are Expeller ring,Expeller,Packing,Packing Gasket,Drinking water Seal Ring ,Packing Gland,Oil Cup
(2) Packing Seal. The routine sealing programs are suited for numerous conditionsand can be utilized in the corrosion or high temperature situations these kinds of as teflon packing,graphite packing etc.It also can be used in strong abrasive situation duty with shaft ceramic sleeve of spray weld. The principal elements are Packing Box,Entrance water seal Ring,Packing,Packing Gland,Shaft Sleeve.
(3)CZPT Seal. World-sophisticated method without having sealing leakage,integrating design,practical set up & substitution,a variety of constructions go well with for all types of problems.High hardness ceramic and alloy are adopted for material of friction elements.Design and style & matching of mechanical seal & sealing box is suitable for fluid state.It possesses high abrasive resistance & shakeproof to assure that sealing impact can be satisfied by customers in a variety of circumstances.The main parts are stationary ring assembly and Movable ring assembly.

Our Workshop Demonstrate:

NAIPU PUMP is a whole processing company, CZPTt from Modeling Workshop,Casting Workshop,Warmth treatment method Workshop,Machining Workshop ,Assembly Workshop and Pump Testing Workshop are all by us. So we are modernization and built-in business to fulfill the prerequisite of the shifting needs of industry.

We established different examine factors together the total creation line,which throughout Uncooked Substance,Charging Content,Surface area and Heat Treatment examining,Material Evaluation,Spare Testing and Pump Testing and many others.

Possible Faults and Settlements 

        Faults      Reason        Settlement
1.Pump fails to discharge any h2o,The hand of pressure gauge beat violently  one.Suction pipe will not have sufficient h2o.
2.Suction pipe blocked or the valve is locked.
1. Inject adequate h2o
2.unlock the inlet valve,distinct the blocks
three.Exclude the air leakage 
two.The pump can’t discharge drinking water,the hand of vacuum meter conquer greatly.  1.The inlet valve is unlocked or silted up.
two.The resistance of suction pipe is way too huge or silted up.
3.The peak of suction is also higher. 
one.Unlock the valve or desilting 
2.increase the design and style of  suction pipe or desilt 
three.Decrease the height of the set up.
three.The pump can not discharge drinking water,pressure gauge shows hefty pressure. 1.The resistance of the discharge pipe is also massive.
2.The impeller blocked
3.The pace is gradual.
one.Verify and change the outlet pipe.
2.Obvious the impeller
3. Enhance the speed.
4.The pump isn’t going to rotate  The volute is silted up by the blocks.  Obvious the blocks
five.The ability is not enough  one.The blocks of the impeller or the inlet or outlet pipe.
2.The abrasion of the impeller is greatly.
three.The pace is minimal to normal 
4.Pump is installed unreasonably or the leakage of the inlet pipe.
five.The transporting top is way too high,the loss of the resistance of the within pipe are way too big.
six.The inlet valve not open up adequate or blocked
seven.The packing seal leaks
one.Clear the impeller or pipe.
2.Change the impeller

3.Adjust the velocity
four.Put in once more or quit leaking.


  1. Decrease the top of the transportation or reduce the resistance.
  2. Unlock the inlet valve


  1. Compress the packing tightly
six.The motor of the pump is overloaded  1.The head of the pump exceeds the head of the functioning issue.
two.Not take into account the slurry density when deciding on the pump.
three.The packing push tightly
one.Turn down the outlet valve,reduce the impeller or lower the pace.
two.Choose the motor once more.
three.Adjust the the screw of the  packing gland 
seven.Abnormal sound in the pump, and no water out 1.The resistance of the inlet pipe is way too large.
two.The height of the suction is also substantial.
3.Cavitation occurred 

  1. there is air in the inlet
  2. The temperature of the liquid is way too high
  1. Obvious the suction pipe and sluice valve.
  2. Reduced the height of the suction 
  3. Change the h2o valve and allow the pump function in the defined limits.
  4. Block the leakage.
  5. Reducing the liquid temperature.
8.pump vibrates 1.pump cavitate 
two.The block of the impeller single vane 
three.The no concentricity  between the pump shaft and motor shaft
four.CZPTeners or basis unfastened
1.Alter the water valve ,decrease the height of the set up,minimize the resistance of the inlet.
2.Distinct the impeller
three.Alignment once again
4.CZPTen the screw,and enhance the basis.
9.Bearing is overheat  1.lock the cooling h2o
2.lubrication is not good.
3.the lubrication oil is not very clear
four.the wrong route of the thrust bearing.
five.there is anything improper with the bearing.
  1. Open up the cooling h2o
  2. Change the oil quantity 
  3. Obvious the shaft,modify oil
  4. According to the inlet pressure,adjust the route of the thrust bearing.
  5. Adjust the bearing 
10.Packing short life  The substance of packing is not good  Change the packing 
eleven.pump leak oil one.Substantial oil stage
2.The rubber parts invalid  
3.Assembly problem
one.Reduce the oil degree
2.Modify rubber spares
three.Adjust the assembly
twelve Pump head leaking  one.The rubber areas not press properly Assembly yet again or press tightly
