Significance of Horizontal Pipeline Centrifugal Pump Model Designations:
For example: ISW100-160 (I) AB

• ISW - Horizontal centrifugal pump

• 100 - Nominal diameter of pump inlet and outlet (mm)

• 160 - Nominal diameter of the impeller (mm)

• I - Flow rate classification

• AB - Impeller undergoes first and second cutting

Product Features of Horizontal Pipeline Centrifugal Pumps

1. Smooth Operation: The absolute concentricity of the pump shaft and the exceptional dynamic and static balance of the impeller ensure stable operation with no vibration.

2. Leak-Free Performance: Hard alloy seals of different materials guarantee no leakage during the transportation of various media.

3. Low Noise: Equipped with two low-noise bearings, the pump operates smoothly. Apart from the faint sound of the motor, there is essentially no noise.

4. Low Failure Rate: The simple and rational structure, combined with internationally advanced quality components for key parts, significantly increases the trouble-free operation time of the entire machine.

5. Easy Maintenance: Replacing seals and bearings is simple and convenient.

6. Space-Saving Design: The outlet can be oriented in three directions—left, right, or upward—facilitating pipeline layout and installation while saving space.

Main Applications of Horizontal Pipeline Centrifugal Pumps

1. ISW Type Pipeline Centrifugal Pump:

• Transports clear water and other liquids with physical and chemical properties similar to water.

• Suitable for industrial and urban water supply/drainage, high-rise building water 增压，garden irrigation, fire fighting systems, and equipment matching.

• Temperature range: $T\le 80^{\circ }\text{C}$.

2. ISWR (WRG) Hot Water (High Temperature) Circulation Pump:

• Widely used in energy, metallurgy, chemical, textile, paper, and hospitality industries for high-temperature hot water circulation and urban heating systems.

• Temperature range: ISWR $T\le 120^{\circ }\text{C}$; WRG $T\le 240^{\circ }\text{C}$.

3. ISWH Horizontal Chemical Pump:

• Transports corrosive liquids without solid particles, with viscosity similar to water.

• Applicable in petroleum, chemical, metallurgy, electric power, paper, food, pharmaceutical, and synthetic fiber sectors.

• Temperature range: $-20^{\circ }\text{C}\le T\le 120^{\circ }\text{C}$.

4. ISWB Horizontal Oil Pump:

• Transports petroleum products such as gasoline, diesel, and kerosene.

• Temperature range: $-20^{\circ }\text{C}\le T\le 120^{\circ }\text{C}$.

Operating Conditions of ISW Horizontal Pipeline Centrifugal Pumps

1. Pressure Requirements:

• Suction pressure ≤ 1.0 Mpa, or the maximum working pressure of the pump system ≤ 1.6 Mpa (i.e., pump suction pressure + pump head ≤ 1.6 Mpa).

• Static pressure test pressure of the pump is 2.5 Mpa. Please specify the system working pressure when ordering. If the system working pressure exceeds 1.6 Mpa, notify the manufacturer separately to ensure cast steel materials are used for flow-through components and connections.

2. Environmental Conditions:

• Ambient temperature < 40°C, relative humidity < 95%.

3. Medium Requirements:

• Solid particle volume content in the conveyed medium ≤ 0.1% of unit volume, with particle size < 0.2 mm.

Note: If the medium contains fine particles, specify this during ordering to ensure the use of wear-resistant mechanical seals.
