Vertical Multistage Fire Fighting Centrifugal Pump

The vertical multistage fire fighting centrifugal pump is designed vertically. Its inlet and outlet are on the same horizontal line with the same diameter, allowing it to be installed in pipelines just like valves. This pump combines the advantages of high pressure of multistage pumps, space-saving of vertical pumps, and easy installation of pipeline pumps. By means of an excellent hydraulic model, it achieves high efficiency, energy conservation, and stable operation. The shaft seal uses wear-resistant mechanical seals to prevent leakage and extend the service life. To better serve users, we have developed a detachable pump body structure. This pump not only retains all the advantages of traditional products but also greatly simplifies the replacement process of vulnerable parts such as mechanical seals, reducing the operation and maintenance difficulty and ensuring the stable operation of the equipment.

Main Applications

Vertical multi-stage centrifugal pump is mainly applicable to the circulation and pressurization of cold and hot clean water in high-pressure operating systems, parallel water supply of multiple pumps in high-rise buildings, fire-fighting, boiler feed water and cooling water systems, and the transportation of various cleaning liquids.

Operating Conditions

Rotational speed: 2960r/min

Flow rate: Q = 1.4 - 192m³/h; Head H ≤ 230m;

Operating voltage: 380V

Ambient temperature: not exceeding 40°C

Altitude: not exceeding 1000m (if exceeded, the motor power needs to be corrected)

Relative humidity: ≤ 95%

Suction pressure of the pump: P1 ≤ 0.3MPa

Outlet pressure of the pump (i.e., the suction pressure of the pump + the head of the pump): P2 < 2.5MPa

The above is the general scope of use. If it exceeds the above range, it needs to be proposed before placing an order for special treatment.
