Amphibious sand-pump--the Fourth Generation Submersible Sand-Pump was firstly developed by Shanghai Qingwu Sand-Pump Research Institute. 25 years of tests with market application, Submersible Sand-Pump successfully obtained four invention patents by continuously research and development. Amphibious sand-pump incorporated multiple advanced technologies,is the most advanced amphibious sand pump at present,which can be used both in water and on the ground..It's exclusive technology features as follow:
Wear-resisting and long service life

 

Normal submersible pump is designed to drainage water or sewage. When water contain sediment, the service life of pump is very short, usually 7 ~ 30 days. If the concentration is high, the service life should be only 1 ~ 2 days.

Amphibious sand-pump is designed to be used for various sand-laden drainage conditions. Working in the environment of large sand and water, the life should be 5 to 8 times longer than normal submersible pump.

Can start and run without water
Amphibious sand-pump allow run without water. The pump's motor will not be burned when the water is thoroughly out.and will normally work when water appear.
Allow starting without water when power supply system capacity is insufficient.
Allowing idling is convenient for installation and maintenance

Amphibious pump
Amphibious sand-pump, which can be used under the water , also can be installed on land by equipped with suction pipe, is a very practical product! It is convenient for installation and maintenance.With it,you will never afraid of flood and submerged pump.

Total head no overload
Amphibious sand-pump can be free to use at a point value between 0 to maximum head. No overload in total head.No worry about burning motor.It is very suitable for head varying working condition. For example: drainage by building mine ,mine rescuing and drainage.

Can be installed in series
Installed in series,one high power pump equivalents to several small power pumps. By starting and running without water, Amphibious sand-pump realizes drainage water and sand in series.The high power pump can not be installed and used in bad conditions,such as power supply system capacity is insufficient, crane capacity is insufficient,or space is limited etc.Amphibious sand-pump,which can be installed in series,easily solves above problems,also reduce the cost of engineering drainage.
The process of installed in series depends on the high quality pump and qualified installation technology.Users do not try without our permission and professional recommendations.

Safe and reliable
Explosion will happens when normal submersible pump drainage water with sand and silt.
While,depends on designs of the explosion-proof parts-- safety valve, water storage room, oil storage room, flame-proof string, discharge pipe, etc.,the Amphibious sand-pump completely eradicate the common explosion hazard and make it safer and more efficient.

Small volume & light weight
Unlike previous casting structure and process, the Amphibious sand-pump is all steel welded structure.
Damageable parts using alloy material. The characteristics of high strength, small volume, light weight make it convenient in transportation,installation and application.

Complete model & all can be customized
High head, small flow of multistage Amphibious sand-pump fill the blank of market.
Large, high-voltage Amphibious sand-pump fill the blank of market.
Amphibious sand-pump,which can be installed in Series, can used both vertically and horizontally ,can be used without jam, can used under the mine , fill the blank of market.
We can also specially design and manufacture products according to the requirements of users .

Automatic drainage
With the characteristics what have been discussed above, the Amphibious sand-pump is your best choice of using in automatic drainage.
