Product Description

Horizontal Multistage Centrifugal Pump D:

D series diesel engine multi-stage pump Brief introduction: The diesel engine multi-stage pump is composed of a diesel engine and a multi-stage centrifugal pump. The pump group is in the form of a horizontal, single-suction, and multi-stage centrifugal pump.
Application :

For transporting clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material and sealing the form of the pump's flow-through components, and adding a cooling system. The axial force is balanced by the balance plate.

Main uses:

1- mine drainage,
2- engineering city water supply and
3- drainage engineering,
4- fire fighting system, etc.


Shaft seals : 

 generally use packing seals, and mechanical seals can also be used according to user needs. The product implements the standard of JB/T1051-93 "Multi-stage clean water centrifugal pump type and basic parameters".

Advantage :

It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation, and maintenance, etc.

Conditions of Use:

1. Ambient temperature ≤50ºC, medium temperature ≤80ºC,
2. The weight of the medium does not exceed 1240kg/m3.
3. The liquid level must be higher than the water inlet of the pump, and idling without liquid is prohibited

Parameter :

Flow	Up to 720m^3/h
Head	Up to 500 m
Speed	Up to 3500 RPM
Power	Up to 500 kW
Caliber	DN25 - DN500 mm

Start, running and stop 

Start
1. First of all, pour water into pipes, to make the pump and inlet pipe filled with water. The pipes shall be sealed, no air leaked. (no-water inside start is forbidden) 
2. Close globe valve and cock on outlet pipe, to reduce start currency.
3. Rotate the rotor by hand, lubricate the bearing and check the pump impeller, seal the ring, if it cannot rotate, you shall not start.
4. Try to start, motor rotation direction shall be as same as the arrow direction on the pump. 
5. When the rotor works normally, open gradually the outlet globe valve, adjust for the work conditions required.

Running

1. Observe the reading in meters, keep it running around the flow and head shown on the nameplate.
2. Regularly check, motor currency value shall not exceed rated currency value.
3. Pump bearing temperature shall not exceed 75ºC, and shall not be 35ºC higher than ambient environment.
4. To start, loosen the stuff cap. Adjust later when started.
5. In case of fragile component abrasion, replace in time.
6. When any abnormal happens, immediately stop and check.

Stop

1. Close the globe valve on the outlet pipe, close the vacuum gauge cock.
2. Stop the motor, and close the pressure cock.
3. In Winter, drain the liquid in the pump completely to avoid frozen cracks.
4. When you will not use it for a long time, uninstall the pump, clean, and lubricate.

Troubleshooting 
 

Fault	Cause	Solution
The pump cannot suck water, pressure gauge & vacuum gauge vibrating	1. Insufficient water pouring  2. Leak between pipe and meter  3. Suction is too high	1, check a leak in the bottom valve.  2, Tighten the leaked part  3, reduce suction
The pump cannot suck, high vacuum is shown in the vacuum gauge	1, bottom valve closed or jammed  2, Too great water suction resistance  3, filter jammed	1, check bottom valve 2, replace water suction pipe 3, clear off the filter
Pressure gauge works, no water outcome	1. Great outlet water pipe resistance 2. Wrong rotation direction  3. Outlet pipe valve closed 4. impeller jammed	1. check or shorten water pipe  2, check the motor, adjust  3, open the valve and clear off the impeller
Cannot reach designed flow	1. air sucked  2. Water level drops, submerged depth is not enough  3. impeller jammed  4. rotor torn and worn	1, check leak part and clear off  2, prolong water inlet pipe, increase the submerged depth 3, uninstall and clear off  4, replace seal ring
Great pump power consumption	1. Stuff tightened, overheated  2. Great flow  3. Collision between rotor and case  4. Pump shaft bearing abrasion  5. Pump shaft misplaced	1. loosen slightly 2. reduce globe valve opening 3. adjust  4. replace bearing  5. replace or adjust
Great pump vibration	1. impeller partially jammed  2. impeller damaged  3. little flow  4. non-concentric between pump shaft and motor. 5, bearing damaged  6, gas etching	1. Uninstall and clear off  2, replace  3, increase opening  4, adjust 5, replace   6, change suction inlet po
