End Suction Fire Pump Driven by Electrical Motor

Introduction of End Suction Pump

The GISO / GIS series end suction pump is a flexible and highly efficient foot-mounted single-stage end suction centrifugal pump with a back pull-out design. It is engineered using advanced CAD (Computer-Aided Design) and CFD (Computational Fluid Dynamics) technologies, ensuring optimized hydraulic performance, high efficiency, and reliable long-term operation.

Manufactured in accordance with international engineering standards and best industrial practices, this pump delivers excellent structural stability, easy maintenance, and strong adaptability to different working conditions.

Thanks to its efficient hydraulic design and flexible configuration, the GISO / GIS series end suction pump is widely used across various industries, including water supply systems, agricultural irrigation, mining operations, and building service applications, providing dependable performance in both municipal and industrial environments.

Design Versions

The GISO / GIS end suction pump is available in two different structural designs to meet various installation and drive requirements:

• The “GISO” long-coupled (frame-mounted) version is designed for belt-driven motor systems, providing strong flexibility for industrial setups that require external transmission.

• The “GIS” close-coupled (stub shaft) version is designed for direct connection with 2-pole or 4-pole IEC standard motors, offering a more compact structure, easier installation, and reduced space requirements.

The standard configuration features a horizontal pump installation with a vertical centerline discharge. In addition, the pump can be installed in multiple orientations depending on system requirements, including alternative discharge directions and flexible mounting positions, with or without vertical pump bearing housing support.

This versatile design ensures compatibility with a wide range of engineering environments and improves adaptability across different industrial and building service applications.

Pumped Liquid 

The GISO / GIS end suction pump is designed for non-combustible, low-viscosity liquids that are free from solids, abrasive particles, and fibers.

Thanks to a selection of high-quality construction materials and customizable seal options, this pump can handle a wide range of liquid chemical compositions, ensuring corrosion resistance, operational reliability, and long service life across various industrial and municipal applications.

This flexibility makes it suitable for water supply, fire protection, irrigation, and process water systems, providing safe and efficient pumping performance for multiple liquid types.

Operating Conditions

• Flow Rate: Max. 2100 m³/h

The pump supports a high flow capacity of up to 2100 m³/h, making it suitable for large-scale water transfer, fire protection systems, and industrial circulation applications that require stable and continuous high-volume performance.

• Pump Head: Max. 160 meters

With a maximum head of 160 meters, the pump is capable of handling medium to high-pressure pumping conditions. This ensures efficient water delivery over long distances and in elevated or high-resistance systems.

• Liquid Temperature: -15°C to +120°C (Standard Version)

Designed to operate across a wide temperature range, the pump can handle both low-temperature and high-temperature fluids. This makes it suitable for diverse applications such as HVAC systems, industrial water processes, and fire protection environments.

• Max Working Pressure: PN16 and PN25 (Optional)

The pump is available with PN16 and PN25 pressure ratings, offering flexible configuration based on system requirements. This ensures safe and reliable operation under different industrial pressure conditions, improving adaptability and system integration.
