The series performance parameters basically comply with the provisions of international standard ISO2858 and national standard JB/T6878.2-93.
There are a total of 67 varieties and 184 specifications in the entire series, with a performance range of 6.3~108m3/h flow rate, 12.5~125m head, equipped with a motor power of 0.37~160KW, and speeds of 1450r/min and 2900r/min.

Product Features
1. The pump structure is compact, the machine pump is integrated, and the volume is small. Its vertical structure has a small installation footprint, balanced operation, and no need for adjustment during installation.
2. The inlet and outlet of the pump are designed with flanges of the same specifications and located on the same centerline. They can be directly installed on the pipeline like valves, and the center is low for easy pipeline layout, making installation particularly convenient.
3. The pump is coaxial with the motor, with a short axial dimension, making the pump run more smoothly and with low noise.
4. Cancelling the traditional shaft seal method avoids the leakage of the conveying medium, thus having the significant feature of completely no leakage.
5. Replacing conventional motor rolling bearings with sliding bearings enables the pump to operate smoothly with extremely low vibration and noise.
6. Easy to install and repair bolts, no need to disassemble the piping system. Simply remove the connecting nut to extract all rotor components for inspection and maintenance.
7. The series and parallel operation of the pump can be carried out according to the requirements of flow rate and head.

STRUCTURE DESCRIPTION
The pump is a machine pump integrated structure, mainly composed of pump body, impeller, connecting body, sliding bearings, stator, rotor, shielding sleeve, motor housing and other components. The pump is a vertical single-stage single suction centrifugal pump, with the inlet and outlet on the same horizontal axis and the same diameter specifications. It can be directly installed on any part of the pipeline like a valve, making loading and unloading extremely convenient and occupying less space. The pump is integrated with the motor through a connecting body, and the bearings are made of imported graphite impregnated resin composite bearings. The motor stator and rotor are isolated by shielding sleeves. The bearing uses liquid as the lubricant and coolant, which has the characteristics of reasonable design and reliable operation. The pump is equipped with a base and can be directly installed on the foundation. Due to its low noise and vibration free characteristics, there is no need to install vibration isolators or pads during installation.

Installation instructions
1. Before installation, check if the fasteners of the unit are loose and if there are any foreign objects blocking the flow inside the pump body to prevent damage to the impeller and pump body during pump operation.
2. The weight of the pipeline should not be added to the water pump during installation, and there should be separate supporting bodies to prevent pump deformation from affecting operational performance and service life.
3. In order to prevent impurities from entering the pump and blocking the flow channel, a filter with a cross-sectional area 3-4 times larger than the suction pipe should be installed in front of the pump inlet.
4. When a pump is used to transport hot water liquids, in order to prevent the pump from being subjected to thermal deformation of the pipeline, the pump may not be fixed with foot bolts. When the pipeline system expands and contracts due to heat, the pump and pipeline can move simultaneously.
5. For the convenience of maintenance and safety of use, a regulating valve should be installed on each inlet and outlet pipeline of the pump, and a pressure gauge should be installed near each inlet and outlet of the pump to ensure normal operation and service life of the pump within the rated range.

maintenance
1、 Preparation and inspection before starting:
1. Check whether the grounding device of the shielded motor and starting equipment is good and complete, whether the wiring is correct, and whether the contact is reliable.
2. For newly installed and long-term disabled shielded motors, the insulation resistance of the motor stator winding to ground should be checked before use.
3. The pipeline must be filled with the conveying liquid, otherwise it will affect the service life of the motor.
2、 Maintenance and upkeep during operation
1. Regularly record changes in power supply voltage and voltage imbalance. Excessive or insufficient power supply voltage, as well as the imbalance of three-phase voltage causing current imbalance, can all lead to motor overheating or other abnormal phenomena.
2. Regularly record the load current and imbalance of the electric pump. When an electric pump malfunctions, it mostly reflects a sharp increase in the current of the stator winding, causing the motor to overheat.
3. Regularly record the infusion temperature in the pipeline to ensure that the actual infusion temperature is lower than or equal to the infusion temperature specified on the nameplate, and to avoid the electric pump running in an over temperature state for a long time, which may reduce the service life of the motor.
4. Regularly record the pressure gauge values on the inlet and outlet ends of the electric pump. The pressure gauge value at the inlet must not be less than zero. The difference between the pressure gauge values at the outlet and the inlet must comply with the pressure values specified on the nameplate.
5. The electric pump must be vented before each use, and during long-term operation, it must be vented once a week. Due to the long-term operation of the pump, water molecules are stirred and impacted at high speed inside the electric pump, and the medium being transported has a certain temperature, resulting in the production of liquid slurry
6. Pay attention to the smell, vibration, and noise of the pump. The winding of the motor will emit a burnt insulation smell due to high temperature. Typical mechanical failures may manifest as vibrations and noise. Therefore, it was found that the abnormality was caused by an immediate power outage for inspection.
7. Regularly check the circulating fluid path of the electric pump and whether there is any blockage in the filtering device.
8. Regularly maintain and measure the gap between graphite bearings and shaft sleeves to ensure even clearance and reliable operation between the stator shielding sleeve and rotor shielding sleeve. In general, the following table is limited. If it exceeds the specifications in the table, it should be repaired or replaced.

Outer diameter of shaft sleeve (mm)
Wear limit clearance (mm)
Standard gap (mm)
>18~30
0.40
0.131
>30~50
0.45
0.158
>50~80
0.50
0.192


9. Regularly check the fit clearance between the impeller mouth ring and the pump body, so the clearance will directly affect the performance of the electric pump. In general, if the clearance exceeds 1.5mm, a new impeller should be replaced. In special cases, repair technology can also be used to improve it.

Starting, running, and stopping
1、 Starting and rotating:
1. Fill the water and exhaust, open the inlet valve to allow the liquid to fully enter the pump chamber, open the exhaust valve at the top of the motor, and close the exhaust valve when it is full.
2. Close the outlet valve to reduce the starting current.
3. Check if all parts are normal.
4. Connect the power and start the engine to determine the correct direction of operation.
5. Gradually adjust the opening of the outlet valve to ensure that the pump operates within the rated performance range as much as possible.
6. If any abnormalities are found during the operation of the pump, it should be stopped immediately for inspection and troubleshooting.
7. Check if the motor current value and temperature rise meet the requirements.
2、 Parking
1. Close the valve of the discharge pipeline.
2. Cut off the power and stop the motor from running.
3. Close the inlet valve.
4. If the pump is not used for a long time, the liquid inside the pump should be drained completely.
