ISWH chemical stainless steel pipeline pump
**ISWH Chemical Stainless Steel Pipeline Pump**
**Overview**
The ISWH horizontal stainless steel pipeline pump is designed using Zui’s advanced hydraulic model, combining the performance characteristics of the IS-type centrifugal pump with the unique structural design of a vertical pump. It is manufactured in strict compliance with international standards such as ISO 2858. The pump features a hard alloy mechanical seal, ensuring energy efficiency, reliable operation, and ease of installation and maintenance.
**Main Features of the Horizontal Stainless Steel Pipeline Pump**
1. **Smooth Operation**: The pump shaft is perfectly concentric, and the impeller has excellent dynamic and static balance, resulting in smooth running without vibration.
2. **No Leakage**: Different types of carbide seals are used to prevent leakage when handling various media.
3. **Low Noise**: With two low-noise bearings, the pump runs quietly, producing minimal noise except for the motor sound.
4. **Low Failure Rate**: A simple and rational structure, combined with high-quality international components, ensures long service life and stable performance.
5. **Easy Maintenance**: Replacement of seals and bearings is straightforward and convenient.
6. **Space-Saving Design**: The outlet can be positioned on the left, right, or top, allowing flexible pipeline arrangement and saving space.
**Main Applications of the ISW Horizontal Pipeline Pump**
1. **ISW Clean Water Pump**: Suitable for conveying clean water or liquids with similar physical and chemical properties. Ideal for industrial and municipal water supply, high-rise building pressurization, irrigation, fire boosting, and cold/warm water circulation. Operating temperature: ≤ 80°C.
2. **ISWR Hot Water Pump**: Widely used in metallurgy, chemical, textile, paper, and hotel industries for boiler hot water circulation and urban heating systems. Operating temperature: ≤ 120°C.
3. **ISWH Stainless Steel Pipeline Pump**: Designed for non-corrosive and low-viscosity liquids, suitable for oil, chemical, power, paper, food, pharmaceutical, and synthetic fiber industries. Operating temperature: -20°C to +120°C.
4. **ISWB Oil Pump**: Used for transporting gasoline, kerosene, diesel, or flammable/explosive liquids. Operating temperature: -20°C to +120°C.

**Preparation Before Starting the Horizontal Stainless Steel Pipeline Pump**
1. Check if the motor rotates correctly (clockwise from the top). Keep the test short to avoid dry wear of the mechanical seal.
2. Open the exhaust valve to fill the pump completely, then close it once full.
3. Ensure all parts are functioning properly.
4. Turn the pump by hand to allow lubricating fluid to reach the mechanical seal.
5. For high-temperature models, preheat at a rate of 50°C/hour to ensure even heating.
**Startup Procedure**
1. Fully open the inlet valve.
2. Close the discharge valve.
3. Start the motor and check for normal operation.
4. Adjust the outlet valve to the required working condition. If flow meters or pressure gauges are installed, operate the pump at the rated point specified in the performance table. Monitor motor current to stay within the rated range.
5. Check the mechanical seal leakage (less than 3 drops per minute).
6. Monitor motor and bearing temperatures (≤70°C).
**Shutdown Procedure**
1. Cool down high-temperature pumps at a rate of <10°C/min until below 80°C.
2. Close the discharge valve.
3. Stop the motor.
4. Close the inlet valve.
5. Drain the pump if it will be parked for an extended period.
**Common Failures and Solutions**
| Failure Form | Cause | Solution |
|--------------|-------|----------|
| No water output | Inlet valves not open, blockage, wrong motor direction, suction leaks, air in the pump, low suction pressure, excessive resistance | Check and remove obstructions, adjust motor direction, tighten seals, vent air, inspect suction system, reduce pipe resistance |
| Insufficient flow | Partial blockage, low voltage, worn impeller | Remove obstructions, regulate voltage, replace impeller |
| Excessive power | Overloaded, high suction, worn bearings | Adjust flow, reduce suction, replace bearings |
| Noise and vibration | Unstable pipeline, gas in liquid, cavitation, damaged bearings | Stabilize pipeline, increase suction pressure, reduce vacuum, replace bearings |
| Motor overheating | Overloaded, internal friction, damaged bearings, low voltage | Reduce flow, check for friction, replace bearings, regulate voltage |
| Leaking | Worn mechanical seal, cracks in pump body, uneven sealing surface, loose bolts | Replace seal, repair or replace pump, trim surface, tighten bolts |
**Installation Instructions for the Horizontal Stainless Steel Pipeline Pump**
1. Before installation, check fasteners and ensure no foreign objects are in the pump.
2. Avoid applying weight to the pump during installation to prevent deformation.
3. Tighten anchor bolts to prevent vibration damage.
4. Install control valves and pressure gauges for safety and performance monitoring.
5. Ensure the impeller moves freely after installation.
6. Choose between rigid or flexible connection based on application requirements.
**Working Conditions of the Horizontal Stainless Steel Pipeline Pump**
1. Suction pressure ≤1.0 MPa, system pressure ≤1.6 MPa. Static pressure test: 2.5 MPa.
2. Ambient temperature <40°C, relative humidity <95%.
3. Solid particle content in the medium: ≤0.1% by volume, particle size <0.2 mm.
Note: If the medium contains small particles, specify this when ordering to ensure a wear-resistant mechanical seal is used.
