Stainless steel centrifugal pump for submersible or surface installation

Traditional water pumps: Can only be used on the ground or submerged (due to motor
waterproofing and heat dissipation issues), making it impossible to combine both
functions. By addressing ground motor heat dissipation and submerged motor sealing
waterproofing, these two functions are integrated into one solution. The QBW
amphibious pump can be used both on the ground and fully submerged, featuring self-
priming capability (within 4 meters). Made of duplex stainless steel, it is rust-
resistant with a service life exceeding 20 years.
1. Advanced sealing design (featuring three independent mechanical seals), ensuring
that the failure of any individual seal does not compromise the structural
integrity of the overall sealing system;
2. Utilizing a high-temperature silicone wax duplex steel casting process, the
product features an attractive appearance, is free of sand holes, offers high
corrosion resistance, and is lightweight, with castings made of 316L or duplex
steel material;
3. The stator and rotor cores are made of 470 non-oriented silicon steel; advanced
three-dimensional impeller and flow path designs are adopted, both domestically and
internationally;
4. The cable uses fluororubber and nitrile rubber, offering corrosion resistance,
aging resistance, and expansion resistance, with an insulation grade exceeding 1000
megohms;
5. Motor: Designed for submersible pumps, with IPX8 protection, corrosion-resistant
316L stainless steel, and Class F insulation;
6. The multi-purpose water pump features multiple relocation methods: a user-
friendly manual relocation handle design and a crane relocation lifting ring
design;
7. Features an internal water circulation design; the submersible pump can operate
dry for drainage; employs three independent mechanical seals made of alloy, with
distilled water lubrication to prevent secondary water source contamination
(traditional submersible pumps both domestically and internationally use oil
lubrication, which may leak and contaminate water sources)
Product Features:
1. No need to build reservoirs or water tanks, no secondary water pollution;
2. High efficiency and energy saving; it can fully utilize the original pressure of
the tap water network and add water pressure;
3. No need to construct pump houses or reservoirs; reduce investment by over 60%;
4. Energy-saving equipment ensures uninterrupted water supply during power outages
(restoring the original pipeline network pressure);
5. Low noise level, ensuring residents' rest is not disturbed;
6. Long service life and rational design (utilizing foreign technology; employing
new materials, advanced domestic and international processing techniques, casting
technology, and high-quality supporting components);
7. The pump is easy to install and flexible, with a compact size—it can be mounted
on the ground, placed in a pool, installed at high elevations, mounted on rooftops,
or installed at staircases, walkways, and pipe ladders, both horizontally and
vertically;
8. The casing is beautiful, with a comfortable feel and no rust;
9. When using a single submersible pump for drainage; the low water level can
exceed 1cm;
