IS/ISR(H)Single Stage End Suction Centrifugal Pump Introduction

The IS/ISR(H) pump is a single-stage, single-suction centrifugal pump designed to ISO standards for clean water (IS), 

hot water up to 130°C (ISR), or light oil (ISY). It is widely used in industrial/municipal water supply, irrigation, and HVAC 

applications due to its energy efficiency, simple design, and reliable pumping of liquids similar to water. 

The abbreviation "IS" denotes standard use for clean water, "ISR" for hot water (high temperatures), and "H" often 

denotes a horizontal, high-power model pumping water/liquids through a single impeller for a variety of applications.

Key Features:

Single-Stage: Uses a single impeller to pump liquid.

Single-Suction: Liquid enters the impeller from only one side (axially).

End suction: The housing design through which the liquid exits makes it compact and easy to install.

Versatility: Various versions (IS, ISR, ISY) handle clean water, hot water, or light oils.

Energy Saving: Energy-efficient design promoted in China.

Applications:

Urban and Industrial: Water supply, sewerage, heating systems.

Agriculture: Irrigation of land and farms.

Industrial processes: Metallurgy, chemical industry, printing, dyeing, ceramics.

Model options:

IS: For clean water (max. 80°C).

ISR (or IS(H)): For circulating hot water (up to 120-130°C).

ISY: For light oils such as gasoline and diesel fuel (not discussed in this section, but relevant).
