ISW Horizontal Centrifugal Pump
Single-Stage Horizontal Centrifugal Pump for Water Supply & HVAC Circulation
ISW horizontal centrifugal pump is a single-stage single-suction pump designed for industrial and municipal water supply, high-rise building pressure boosting, HVAC circulation and general clean-water transfer. The direct-coupled horizontal structure integrates the pump and motor in a compact arrangement, helping simplify installation while providing reliable operation in pipeline water systems. Standard ISW models are mainly used for clean water and liquids with similar physical and chemical properties. ZLZB® supplies ISW pumps with model selection based on required flow, head, liquid temperature, pipeline size and operating conditions.
Flow Range:
2.5-1200 m³/h
Head Range:
10-180 m
Power Range:
0.18–250 kW

FAQ
-
How do I select the right ISW horizontal centrifugal pump?
Select the pump according to required flow, head, liquid temperature, pipeline size and operating conditions. ZLZB® can recommend a suitable ISW model based on your system requirements. -
What are ISW horizontal centrifugal pumps mainly used for?
ISW pumps are commonly used for industrial and municipal water supply, building pressure boosting, HVAC circulation, cooling-water systems and general clean-water transfer. -
What is the difference between ISW and ISWR centrifugal pumps?
Standard ISW pumps are mainly designed for clean-water service, while ISWR models are intended for compatible hot-water applications. The appropriate version should be selected according to liquid temperature and operating conditions.
-
Can ISW pumps be used for high-rise building pressure boosting?
Yes. ISW pumps can be applied in building water supply and pressure-boosting systems when the selected flow, head and system conditions match the required operating point. -
What liquids are suitable for an ISW horizontal centrifugal pump?
Standard ISW pumps are suitable for clean water and liquids with similar physical and chemical properties without significant solid particles. For corrosive or special liquids, a suitable material and pump configuration should be selected. -
What information is required for an ISW pump quotation?
Please provide the required flow, head, liquid temperature, application, pipeline size, voltage and frequency. ZLZB® can then recommend a suitable ISW pump model and prepare a quotation.
