Shanghai Longzhou Deep Well Fire Pump XBD5.0/10GJ-BYSJ, 11KW

Advantages of the XBD new series vertical long shaft fire pump:

1. Introducing American company hydraulic models and structural designs, utilizing Ashland process core technology, epoxy coating on blade channels, and other advanced techniques. Components are made with imported NTN bearings to minimize wear, capable of withstanding 120 degrees Celsius high temperature; and German Eger Borgmann mechanical seals, resistant to acids and alkalis, with a long service life.

2. Equipped with a sand-ejecting ring, the labyrinth structure prevents sand particles from entering the bearings.

3. Non-welded, one-piece cast stainless steel impeller with anti-clogging design; precision-machined stainless steel shaft with radial跳动 no more than 0.13mm, ensuring smooth operation and low noise.

4. Utilize QT450 ductile iron and HT250 stainless steel materials in various grades to meet the diverse special operating conditions and technical requirements of our customers.

5. The pump head is fully submerged in the liquid, eliminating any self-priming time. The pump starts with simultaneous pressure and water supply.

6. The impeller of the pump is immersed in water, requiring no bottom valve, no need for priming water or shaft vacuum, and can be directly started, offering great convenience and reliability; 3. It can be installed directly on top of the water tank, with just two support beams and a channel steel beam for support and fixation, without the need for an suction pipe.

7. Submersible pumps have a water suction height of approximately ten meters, featuring a vertical structure with minimal land area and low infrastructure investment.

8. Submerged length can be customized according to the pool depth.

Operating Principle and Structure Description

Pump Working Principle: The motor drives the impeller, which rotates submerged in the liquid, to gain energy. After the fluid receives energy from the impeller, it is redirected by the guide vanes and rises vertically through the channel between the inner and outer tubes. It then exits horizontally through the outlet bend.
