Ultimate Guide to ISUZU Fire Truck Pumps: Types, Performance & Maintenance
June 06, 2025
ISUZU fire trucks are widely recognized in the global firefighting industry for their reliability, efficiency, and adaptability. As the core component of a fire truck, the performance of the fire pump directly impacts firefighting efficiency. ISUZU fire trucks are typically equipped with various pump models, such as CB10/20, CB10/30, CB10/40, CB10/60, CB10/80, and CB10/100, to meet different firefighting scenarios. This article provides a detailed introduction to the applicable vehicle models, working principles, and maintenance methods for these fire pumps, helping users better understand and operate ISUZU firefighting trucks. 1. Common Fire Pump Models for ISUZU Fire Trucks and Applicable Vehicle TypesISUZU fire trucks are equipped with fire pumps of different specifications based on load capacity and functional requirements. Common models include CB10/20, CB10/30, CB10/40, CB10/60, CB10/80, and CB10/100, where the numbers represent the pump's flow rate (L/s) and pressure (bar). For example, CB10/40 indicates a flow rate of 40 L/s and a pressure of 10 bar.• CB10/20, CB10/30: Suitable for light-duty ISUZU fire trucks (e.g., ISUZU NKR or NQR fire vehicles), primarily used for community firefighting and small-scale fire suppression.• CB10/40, CB10/60: Commonly found in medium-duty ISUZU fire trucks (e.g., ISUZU FTR or FVR fire engine), suitable for urban firefighting, industrial zone fire suppression, and other high-demand tasks.• CB10/80, CB10/100: Mainly used in heavy-duty ISUZU fire trucks (e.g., ISUZU GIGA firefighting trucks), designed for large-scale fires, airport firefighting, and other high-flow scenarios.Main parameters for fire pump: Model Work condition Flow rate (L/S) Outlet pressure (Mpa) Rated speed (r/min) Power (KW) Suction depth (m) CB10/20 1 20 1.0 3135±50 34 3 2 14 1.3 3440±50 35 3 3 10 1.0 3059±50 22 7 CB10/30 1 30 1.0 3010±50 48 3 2 21 1.3 3340±50 52 3 3 15 1.0 3000±50 34 7 CB10/40 1 40 1.0 3080±50 60 3 2 28 1.3 3360±50 61 3 3 20 1.0 2990±50 39 7 CB10/60 1 60 1.0 3200±50 102 3 2 42 1.3 3475±50 106 3 3 30 1.0 3130±50 73 7 CB10/80 1 80 1.0 3400±50 137 3 2 56 1.3 3500±50 130 3 3 40 1.0 3130±50 83 7 CB10/100 1 100 1.0 2270±50 149 3 2 70 1.3 2320±50 138 3 3 50 1.0 2050±50 115 7 These fire pumps adopt a centrifugal design, offering high efficiency, stability, and durability, meeting the operational needs of various ISUZU fire engines.2. Working Principle of Fire PumpsThe fire pumps installed in ISUZU fire trucks are typically centrifugal pumps, which operate based on centrifugal force. When the engine drives the pump shaft to rotate, the impeller spins at high speed, causing water to flow rapidly within the pump casing. Due to centrifugal force, water is pushed outward, forming a high-pressure stream that is delivered through the outlet to fire hoses or nozzles.The advanta...
