CB10 60 water fire fighting truck pump

The CB10/60 water fire fighting truck pump is a specialized, non-self-powered pump mounted on a fire truck chassis, designed to deliver water or foam solution for fire suppression.

It primarily consists of low pressure and high-pressure (or medium-pressure) centrifugal pumps, a gearbox, a piston priming pump, a foam proportioner, control valves, and instrumentation; its fluid-handling components are predominantly constructed from high-strength aluminum alloy and stainless steel.

 ». Performance Characteristics

The CB10 60 fire pump is characterized by a compact structure, light weight, comprehensive functionality, ease of maintenance, safe and reliable operation, excellent performance, high efficiency, and user-friendly operation.

Its core performance features include high pump unit efficiency and excellent cavitation resistance, alongside capabilities such as high energy efficiency, rapid response, high-head and high-flow output, adaptability to extreme operating conditions, and high reliability.

 ». Feature Overview
The fire engine equipped with the CB10/60 system features automatic priming capabilities, allowing it to draw external water directly into the pump for firefighting operations without the need for auxiliary priming equipment. It supports foam firefighting operations using either 3% or 6% foam mixtures.

The pump assembly offers a range of operating modes, including low-pressure, high-pressure (Stage I and Stage II), and combined high/low-pressure modes.

». Working Principle

➤ The core component of the CB10/60 fire pump is a centrifugal pump. Its operating principle is as follows: when the pump is in operation, the impeller rotates at high speed, throwing water toward the impeller's outer edge under the influence of centrifugal force; the water is then collected and pressurized within the volute casing before being discharged.

 

 

➤ Since centrifugal pumps lack self-priming capability, vehicle-mounted pumps intended for mobile use must be equipped with a priming device (such as a vacuum pump) to evacuate air and create a vacuum, thereby drawing water into the pump.

The typical operating procedure is as follows: start the engine and engage the pump gear to drive the pump shaft; operate the priming device to extract air and create a vacuum; once the pump is filled with water, deactivate the priming device; then open the discharge valve and adjust the engine throttle to supply water.
