Split case fire fighting pump
pump outlet diameter: 80-200mm
Capacity: 20~200L/S
Head: 0.2~2.5Mpa
Suction depth: 3.0m
Split case fire fighting pump is in full compliance with NFPA standards.
1.1 Shut off head is less than 1.4 times of the designed head.
1.2 When the capacity is 1.5 times of designed capacity, the head will be higher than 65% of the designed head.
1.3 Each pump will be made the hydraulic test before delivery in the case of the test pressure is for 1.5 times of inlet pressure plus working pressure.
1.4 Maximum test pressure can be achieved 5Mpa to meet some specific applications.
1.5 Being the structure of single stage double suction, it is easy to maintenance and assembly with lower maintenance cost.
1.6 Pump head can be up to 280m to adapt to most of fighting applications.

Technical advantage
With short supporting distance in the both ends of the pump, the pump, the pump is running smooth, low vibration and noise.
Excellent hydraulic model, high efficiency, high efficiency zone width, cavitation performance
With inlet and outlet along the same line, pipeline layout is simple, convenient and beautiful
Pump body can be installed either horizontal or vertical according to user's site conditions.
Deep absorption can reduce the land space investment and extend the life time of pump.
No need to disassebly the the import and export pipeline, easy maintenance, low cost.

We are the largest richest boiler, mine pump, multistage, split case pump, chemical and fire fighting, turbine diesel pump set manufacturer in China.

The diesel pump set is very stable and famous made in our company, the power can be up to more than 1000 KW by Cummins, cat diesel drive.

The pump can be made for API610, NFPA standard.
