• Possible cause : gaskets are broken or there is a hole.
  • Solution : replace the gaskets. If there is a possibility of closing, close it, otherwise replace the part.

Possible cause clogged suction line
Solution clear obstacles
 
Possible cause fan blades clogged with foreign matter
Solution clean fans

-Possible reason is the service water is not enough.
Set by solution catalog value
-Possible cause high service water temperature
The solution is supply cold water
-Possible cause pump rotation reversed
Adjust according to the arrow direction on the solution pump label
-Possible cause calcification of pump parts
The solution is clean up, pick up again


• Possible cause Incorrect flat setting

• Re-adjust the solution coupling planar

• Possible cause service water is hot

• Solution Provide cold water

• Possible cause pump and motor planar alignment incorrect (coupling alignment)
• Re-adjust solution coupling
• Possible cause Shaft, bearing or fan broken
• Solution replace broken parts
• Possible cause service water flow is high
• Set by solution catalog value


• Possible cause Foreign matter has gone inside

• Solution clean and extract 

• Possible cause One or more of the fan blades is broken

• Solution replace broken part

• Possible cause Soft packing thrust gland not adjusted properly
• Tighten solution pressure glen studs
• Possible cause Packing not installed properly
• Solution Check and reseat the gland packing.
• Possible cause Mechanical seal parts worn
• Solution replace wearing parts
• Possible cause Shaft worn
• Solution Change shaft.

 
The pump rotation direction is indicated by an arrow on the pump label. (Clockwise when viewed from the engine side) 
Press the switch for a short time and check whether the pump rotates in the direction of the arrow.
If you have removed the coupling guard for this operation, replace it immediately.
 

This value may vary depending on ambient conditions.

90° sharp tiles and the use of small pipe diameters for large capacity pumps are issues to be avoided.

The most important rule is never to install pipes with a diameter smaller than the air inlet diameter of the pump.

Small diameter pipes reduce efficiency and give the same result as a person trying to breathe with a straw.
 

 Use 10% oxalic acid solution to clean the limescale and deposits that may form inside the pump and apply in 30-minute periods.
 Mechanical seals are maintenance-free.
 Bearings are covered on both sides and do not require lubrication until the end of the bearing life.
 If the pump is to be disassembled, the dangerous substances (acidic, basic) that may remain in the pump must be emptied without any previous contact.
 Hazardous substances remaining in the pump may cause interruption in the pump fluid.
 If there is a filter in the system, do not remove the filter without stopping the pump.

• If the pump will not work for a long time:
• Drain the water in the pump by removing the plugs on the pump body.
• Fill the pump with some protective oil and turn the pump shaft until all the parts inside the pump are lubricated.
• Close the openings of the pump.
• Store the pump in a closed, clean and dry environment free from frost.
• Protect the pump from vibration.
• Change the protective oil in the pump every three months.
