XBDS vertical multistage centrifugal pump(fire pump)

XBDS vertical multistage centrifugal pump is a type of fire pump that is commonly used in high-rise buildings, industrial facilities, and other areas where water needs to be quickly and efficiently transported. This pump provides high pressure and flow rates, making it ideal for firefighting applications.

The XBDS pump is made of high-quality materials such as stainless steel, thus offering maximum durability and reliability. It also features a compact and efficient design that allows for easy installation and maintenance. The pump's vertical structure enables it to occupy less space while providing the same performance as other pumps.

One of the unique features of the XBDS pump is its multistage design. The pump comprises several impellers that operate in series, increasing the pressure and flow rate of the water. This design provides higher efficiency compared to single-stage pumps.

The XBDS pump is also equipped with a range of safety features to ensure reliable and safe operation. These features include overheat and overload protection, as well as fail-safe mechanisms that prevent the pump from overheating or overloading in case of failure.

The XBDS pump is widely used in fire protection systems and is designed to comply with all relevant safety standards and regulations. It is also suitable for use in other applications that require high-pressure water transfer, such as irrigation, HVAC systems, and water treatment.

In conclusion, the XBDS vertical multistage centrifugal pump is a reliable, efficient, and safe fire pump that can be used in a wide range of applications. Its multistage design provides superior performance while maintaining a compact footprint, making it an ideal choice for high-rise buildings and other areas where space is limited. This pump is an excellent investment for anyone looking for a high-quality, long-lasting fire pump.

Parameters

Flow rate	Q=6.3~200m³/h
Total head	H=8~150m
Suction head	H=5~7m
Speed	n=2900rpm
S.g.	γ ≤1.1
Temperature	T=-15～105℃
Pump diameter	25~150mm

Features

Advanced hydraulic models of high efficiency and better performance.
Only 2900 rpm is available,the dimension is smaller compared to old DL series which speed is 1450 rpm. Therefore,it takes smaller space and saves cost in construction.
Compact structure,can be installed outdoor with shelter.
Special mechanical seal with advantage of easy maintenance.
Various materials for different temperature and pressure.

Structure

Vertical, multistage and sectional structure. The inlet section, middle section and outlet section are tightly connected by bolts.

One impeller+a guide vane for every stage, the axial force is hydraulically balanced, the bearings bear the rest axial force.

During the maintenance, the mechanical seal can be removed out by dismantle the clam couplings in the middle, no need to dismantle motor.

Pump inlet is at the bottom of casing, while pump outlet is at the top of casing. The relative angle of pump inlet and outlet can be customized as 0°, 90°, 180°, 270°.
