Product Overview

The XBD-IS Horizontal Single Stage End Suction Fire Pump is a direct-coupled centrifugal fire pump designed for reliable water supply in fire protection systems. Its horizontal end suction structure with common base plate and coaxial motor mounting provides stable flow, low vibration and easy maintenance for building, commercial, industrial, and municipal fire protection applications.

With flow rates from 5 to 200 L/s and heads from 30 to 120 m, the pump can be configured according to project-specific hydraulic requirements. Cast iron casing, bronze impeller and mechanical seal are standard; electric motor drive, complete fire pump set configurations and flange sizes from DN50 to DN200 are available for different system designs and local fire code compliance.

Each pump is performance tested before shipment, and technical documentation, dimensional drawings and selection support can be provided for project evaluation.

Product Advantages

High-Efficiency Hydraulic Design

Optimized volute casing and precision-cast bronze impeller deliver pump efficiency up to 82%, one of the highest levels for single-stage end suction fire pumps, significantly reducing energy consumption and long-term operating costs. The flat head-capacity curve ensures stable discharge pressure from zero to rated flow, and the non-overloading motor power characteristics across the entire pump curve fully meet NFPA 20 and local fire code requirements without risking motor trip during overload conditions.

Back-Pull-Out Easy Maintenance

The rear bearing bracket design allows the entire rotating assembly, including impeller, mechanical seal and bearings, to be withdrawn as a single cartridge without disconnecting the suction and discharge piping, reducing impeller, seal or bearing replacement to under one hour of downtime. This design also eliminates the need to realign the pump and motor after maintenance, ensuring fast recommissioning and minimal disruption to the fire protection system.

Corrosion-Resistant Construction for Long Service Life

Standard cast iron pump casing with bronze impeller and renewable cast iron wearing rings provide reliable performance in clean water service; 304 or 316 stainless steel wetted parts are available for corrosive water conditions. The silicon carbide mechanical seal delivers zero-leakage operation with service life over 8,000 hours, and every pump is hydrostatically tested at 1.5 times working pressure before shipment to guarantee structural integrity.

Flexible Configuration & OEM Support

Dual-pump duty/standby arrangements, variable frequency drive, diesel engine drive and complete fire pump set configurations are all available to match different project requirements. Flow rates from 5 to 200 L/s and heads from 30 to 120 m cover a wide range of fire hydrant and sprinkler system demands, and private-label branding, custom control logic and local fire code configurations are fully supported, with every unit factory performance tested to verify flow-head curves within ±5% of rated values.
