Introduction
XBD series vertical multistage fire pump group is a new generation of vertical multistage fire pump group developed by our company according to the needs of domestic and foreign markets and the advantages of foreign centrifugal pump structure with CAD technology. More than 60 ºC water and water-like liquid, using a special hydraulic design and structural design, so that the flow pressure of sub-file than ordinary centrifugal water pump fire water supply system is more suitable for construction, flow-pressure curve is flat without hump. High reliability due to wear-resistant, corrosion-resistant, anti-mesh materials for all parts that generate friction due to rotation. Multi-stage pump can be equipped with double water outlet, high carrying capacity of pump body, strong anti-overload capability .
Application
XBD-type fire pump for conveying temperature does not exceed 60 ºC water and water-like liquid. Can also be applied to industrial city water supply and drainage, high-rise building pressurized water supply, long-distance water supply, heating, bathroom, boilers, heating and cooling water circulation pressurized air conditioning and cooling system water supply and equipment and other occasions.
Advantage
Small footprint, light weight, high efficiency, small vibration, easy maintenance, good corrosion resistance, stable and reliable operation, long life, the use of special hydraulic design and structural design, so that the flow pressure sub-file than ordinary centrifugal water pump More suitable for building fire water supply system selection, flow - pressure curve without hump. High reliability due to wear-resistant, corrosion-resistant, anti-mesh materials for all parts that generate friction due to rotation. Multi-stage pump can be equipped with double water outlet, high carrying capacity of pump body, strong anti-overload capability.
Structure
Vertical multistage fire pump, suction and discharge are horizontal, can be 90 °, 180 °, 270 ° installation, import and export are flanged, from the motor end as a clockwise rotation, the use of shaft seal Machinery Seal.

Model meaning
This serise apply to the fire pump requirement of GB6245-2006.
Model XBD6.0 / 5G-QDL stands for water use, with motor driven, rated pressure of 0.6Mpa, rated flow of 5L / S, vertical multistage fire pump.(None D means fire pump)
Economic Analysis
In the traditional vertical multi-stage fire pump product group to replace the replacement of a new generation of vertical multi-stage fire pump products, in addition to increased price-use capabilities, but also to the user get more benefits. As a new generation of fire pump technology has doubled the technical content, reducing manufacturing costs and truly enhance the quality standards in the same time, but also enhance the market competitiveness and economic value.
| A new generation of vertical fire pump | Traditional vertical fire pump group |
| The new generation of fire pump group changed the previous design ideas, using a novel axial force balance device, and greatly reduce the size, effectively reducing manufacturing costs, but also reduces the pump room area, so that the user a one-time building Investment, equipment investment costs reduced by 30% to 40%. | Due to the large size of traditional vertical fire pump group, overweight, high manufacturing costs and installation and maintenance brought a very inconvenient shortcomings. |
Install and use
A, installation
1, must be checked before installation, hand rotation, rotor rotation must be free.
2, the use of anchor bolts connected with the ground, through the pump base and foundation between the thick enough of the horn on the base point leveling.
3, supporting the output pipe, pump device to avoid additional load, the pump outlet with a flexible connector and output pipe phase, in order to install and shock absorption.
4, each pump has an independent inlet pipe, using self-filling suction.
B, use
1, Do not start the pump in the absence of water
2, the first time before the start of the following procedures should be operated
1, safe to close the pump outlet valve
2, the first diversion, open the inlet valve water, loosen the pump on the deflation bolts deflated, after the water spray tightness bleed bolt
3, point pump, from the drive side, the pump rotates clockwise
4, slowly open the outlet valve, adjusted to cause the rated condition
3, in the case of the outlet valve is closed, the maximum working time of the pump should be less than 3 minutes
Maintenance instructions
Vertical multistage fire pump shaft seal with mechanical seal, work in the formation of a layer of liquid film between the end, in addition to the beginning there may be a small amount of leakage, the seal will not leak the normal work.
When replacing the shaft seal, proceed as follows:
A, remove the coupling screw, remove the coupling and motor, open the seal cover;
B, wash all seals with water, replace worn or damaged parts;
C, in order to facilitate the assembly of seals, all parts in direct contact with the O-ring to wet with soap and water.
When reassembling the motor and pump, the coupling should be correctly positioned and the stop must be closed. If installed outdoors, it should be ensured that the intrinsically safe installation is well protected from the weather conditions.
Service matters
The company can help users choose products.
Due to the poor quality of manufacturing products and can not work, the company responsible for free replacement.
The company implemented a lifetime of maintenance products sold.
