For the transport of water or other physical and chemical properties similar to water. Mainly used in urban high-rise building water supply and drainage and fire water, factories, mining drainage, long distance water delivery, water production process cycle, HVAC cycle, domestic water and other purposes.



                                                                      Features

1, advanced hydraulic model, high efficiency, wide range of performance.

2, pump running smoothly, low noise.

3, the shaft seal adopts the soft packing seal or the mechanical seal, the seal is safe and reliable, the structure is simple, the maintenance is convenient and quick.

4, the shaft is full seal structure to ensure that no contact with the media, no corrosion, long service life.
                                   Parameters

Q=5~55m³/h	H=39~576m

Dna=40~100mm	DNm=40~100mm

                                                                    Conditions
Horizontal multistage centrifugal pump is mainly used for urban high-rise building water supply and drainage and fire water, water supply and drainage of factories and mines, long distance water delivery, water production process cycle, HVAC cycle, domestic water and other purposes.

1, horizontal multistage centrifugal pump is suitable for conveying water and physical and chemical properties similar to water, the volume of solid insoluble matter does not exceed 0.1%, particle size ≤ 2 mm.

2, horizontal multistage centrifugal pump medium temperature: -15 ºC ~ 80 ºC

3, horizontal multistage centrifugal pump working pressure: system pressure ≤ 3.0MPa.

That is: system pressure ═ inlet pressure + pump working pressure ≤3.0MPa.

4, the ambient temperature should be below 40 ºC, relative humidity should not exceed 95℅.

5, As the pump main components are made of cast iron, so the transmission medium should be no corrosive.

Note: If the medium with small particles or a strong corrosive.
Installation matters
                                   Installation matters
1, the pipe weight should not be on the pump when installed, otherwise easy to damage the pump;

2, the installation must be tightened anchor bolts, and each interval of time to check the pump to prevent its loosening, so as to avoid the pump start violent vibration and affect the performance of the pump;

3, before installing the pump should be carefully checked whether there is any impact on the pump runner pump running hard materials (such as stones, iron sand, etc.) in case of damage to the pump running over-current components:

4, in order to maintain the convenience and safety of use, install a regulating valve on the pump inlet and outlet piping and a pressure gauge near the pump inlet and outlet, for high lift pump, to prevent water hammer, should also be installed before the outlet gate A check valve to cope with the loss of power and other sudden power outages and the production of accidents, so as to ensure that the pump running in the best conditions to extend the service life of the pump;

5, pump suction there occasion, should be equipped with the end of the valve, and the inlet pipe should not have too many corners, while no leakage, leakage phenomenon, so as not to affect the suction pump performance;

6, in order not to make impurities into the pump blockage flow channel affect performance, should be installed in front of the pump inlet filter;

7, before installing the rotor pump rotor components, there should be no friction or stuck phenomenon, or should open the pump to check the reasons.
                                 Maintenance
Pump start-up, operation, downtime maintenance

1, the pump clean around.

2, add calcium-based butter in the bearing. Brake rotor with hand should be flexible without card research phenomenon.

3, try to open the motor, check whether the motor rotation and pump match.

4, Open the vent valve at the outlet flange, fill the pump with water, or use a vacuum pump to draw water.

5, turn off the discharge valve and pressure gauge cock plug.

6, the above work is completed, start the motor, open the pressure gauge cock.

7, when the pump is rotated at normal speed, the pressure gauge at the display, open the vacuum gauge cock and gradually open the outlet gate valve, until the required pressure so far.

8, in operation, the pump bearing temperature shall not exceed the outside temperature of 35 ºC, the maximum temperature of not more than 75 ºC. For every 500 hours of operation, grease the bearings with a high-pressure gun.

9, packing room or sealed room normal water level to 30-60 drops per minute is appropriate, should be adjusted packing gland or mechanical seal gland compaction level.

10, check the coupling regularly, pay attention to bearing temperature.

11, when the pump stops, should choose to close the outlet valve on the pipeline, turn off the vacuum gauge cock; and stop the motor, and then close the pressure gauge cock.

12, the pump found in the rotating abnormal noise, it should immediately shut down to check the reasons.

13, the winter cold season, such as the short-term deactivation of the pump, to be unscrewed into the water on the four-way snail. Will save the water, so as not to freeze the pump.

14, the pump after long-term use, if the flow pressure dropped significantly, you should open the pump inspection, replacement of its vulnerable parts.

Long-term stop using the pump, the pump should be disassembled, the pump parts of the water to dry, remove the rust, and coated with rust-proof grease, and then re-installed properly stored.
