ISW centrifugal horizontal monoblock pump

Single-stage, single-suction horizontal centrifugal pump with a closed-coupled layout suitable for bulk water, oil and chemical transfer. Designed as an evolution of the IS series, this family provides multiple material and configuration options to fit industrial, municipal and commercial pumping duties.

Key features

• Closed-coupling, single-stage single-suction centrifugal design for compact footprint and straightforward installation
• Multiple material options: cast iron, stainless steel; impellers optionally in bronze or stainless steel to match the pumped fluid
• Motor options: standard or explosion-proof motors selectable according to fluid flammability and site classification
• Wide application range: industrial and urban drainage, pressurized water supply (including high-rise), fire booster systems, sprinkler irrigation, HVAC/chiller circulation, boiler feed and hot-water circulation, long-distance transfer and various chemical or petroleum services

Variants and typical service limits

• ISW (general-purpose water/oil): suitable for water and similar liquids; pumped liquid temperature up to 80 °C
• IRW (hot-water centrifugal): designed for hot-water circulation and boiler feed; liquid temperature up to 120 °C
• IHW (chemical duty): for corrosive liquids (no solids) with similar viscosity to water; temperature range approx. 20–120 °C
• ISWB (pipeline oil pump): for gasoline, kerosene, diesel and other flammable/explosive oil products; medium temperature 0–80 °C
• ISWD (low-speed low-noise): for noise-sensitive installations; low speeds such as 1,450 rpm or 980 rpm; liquid temperature up to 120 °C

Typical benefits for B2B buyers

• Flexible materials and motor choices to meet chemical compatibility and hazardous-area requirements
• Multiple variant family covers general water, hot water, chemical and oil-transfer duties—reduces need to source different pump families
• Compact, closed-coupled construction simplifies alignment and reduces installation space and maintenance effort

Available example model

• Example model: ISW50-125 (other sizes and performance curves available across the ISW/IRW/IHW/ISWB/ISWD range). For selection, specify required flow (m3/h), head (m), liquid properties and temperature, and whether explosion-proof motor or special materials are required.
