Product Description
ISW type horizontal inline centrifugal pump is Developed by our technical staff together with domestic pump experts, this pump adopts optimized hydraulic models and performance parameters of IS type centrifugal pumps. It features an ingenious structural design based on conventional vertical pumps. Derivatives for hot water, high-temperature media, corrosive chemicals and oil are also developed according to different operating temperatures and conveyed media. This series boasts high efficiency, energy saving, low noise and reliable performance.It complies with the latest national standard JB/T53058-93 issued by the Ministry of Machinery Industry, and is designed and manufactured in accordance with international standard ISO2858.
Overview
ISW horizontal inline centrifugal pump is used to convey clean water and liquids with similar physical and chemical properties. It is widely applied in industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden irrigation, fire water pressurization, long-distance liquid transmission, HVAC refrigeration circulation, hot and cold water circulation for bathrooms and supporting equipment. The applicable medium temperature is below 80℃.
Structure Description
1. The pump is of horizontal design with identical suction and discharge port sizes and end suction structure. It can be directly installed on inlines, featuring compact layout, small footprint and low construction cost. It can be used outdoors when equipped with a protective cover.
2. The impeller is directly mounted on the extended motor shaft, resulting in short overall axial dimension and compact structure. The well-configured bearings of pump and motor effectively balance radial and axial loads generated during operation, ensuring stable running with low vibration and noise.
3. The shaft seal adopts mechanical seal or combined mechanical seal. Equipped with imported titanium alloy seal rings, medium-duty high-temperature resistant mechanical seals and hard alloy components, it delivers excellent wear resistance and greatly extends the service life of the mechanical seal.
4. Easy for installation and maintenance. There is no need to dismantle the inline system. The entire rotor assembly can be removed simply by loosening the nuts on the pump bracket.
5. The pumps can be operated in series or parallel to meet different flow rate and head requirements.
6. Vertical or horizontal installation is available to adapt to various inline layouts.
Application
ISW type vertical hot water inline pump is suitable for pressurized circulation and transmission of high-temperature boiler hot water in metallurgy, chemical, textile, wood processing, papermaking industries, as well as hotels and bath centers. It is also used for heating circulation in residential buildings, with operating temperature below 80℃.

Start-up and Operation:
1. Rotate the motor fan blade manually. The impeller shall rotate flexibly without jamming or friction.
2. Turn the pump by hand to feed lubricant to the mating faces of the mechanical seal.
3. Fill liquid and vent air. Open the inlet valve to fully fill the pump chamber and the entire pipeline. Ensure the inlet pipeline is well sealed.
4. Close the outlet valve to reduce starting current.
5. Switch on the power and jog the motor to confirm the correct rotation direction. Viewed from the fan blade end of the motor, the pump rotates clockwise.
6. Gradually open the outlet valve to keep the pump running under rated operating conditions.
7. Stop the pump immediately for inspection if abnormal noise is heard during operation.
8. The normal leakage of the mechanical seal shall be less than 3 drops per minute. The temperature rise of the motor and bearings shall be lower than 70℃. Investigate the cause if the limit is exceeded.
Shutdown:
1. Close the discharge pipeline valve.
2. Cut off the power supply to stop the motor.
3. Close the inlet valve.
4. Drain all liquid inside the pump if it will be out of service for a long time.

Fault Symptom Cause of Fault Troubleshooting Method 1. Pump does not deliver water a. Inlet/outlet valves not open, blocked pipelines, or blocked impeller flow passage.
b. Wrong motor rotation direction, or slow speed due to motor phase loss.
c. Air leakage in the suction pipe.
d. Pump not fully primed, air trapped in the pump chamber.
e. Insufficient inlet water supply, excessive suction lift, or foot valve leakage.
f. Excessive pipeline resistance or improper pump selection.
a. Inspect and remove blockages.
b. Correct motor rotation direction and tighten wiring connections.
c. Tighten all sealing surfaces to eliminate air leakage.
d. Fill the pump with liquid, open the vent valve to purge all air.
e. Shut down the pump for inspection and adjustment (this often occurs when connected to municipal water lines or used with high suction lift).
f. Reduce pipeline elbows and select a more suitable pump.
2. Insufficient pump flow a. First check causes listed in Item 1.
b. Partial blockage in pipelines/pump flow passages/impeller, scale buildup, or insufficient valve opening.
c. Low voltage.
d. Impeller wear.
a. First follow troubleshooting steps in Item 1.
b. Remove blockages and readjust valve opening.
c. Stabilize the voltage.
d. Replace the impeller.
3. Excessive power consumption a. Operating beyond rated flow.
b. Excessive suction lift.
c. Worn pump bearings.
a. Adjust flow rate by partially closing the outlet valve.
b. Reduce the suction lift.
c. Replace the bearings.
4. Noise and Vibration
a. Unstable pipeline supports.
b. Gas entrained in liquid.
c. Cavitation occurs.
d. Damaged bearings.
e. Motor operates under overload and overheats.
