ZJQ submersible sand dredging pump

1. Submersible slurry pump

ZJQ submersible centrifugal slurry pumps are mainly used to pump high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, 

refuse ores, ashes, cinders, cements, mud, mineral stones and etc.

2. Application Condition

1— Power: 50/60HZ, 380V/460V/660V, 3-Phase.
2— Medium Temperature: Max. 40°C and without explosion gas.
3— Slurry Concentration By weight up to 60%.
4— Max submersible depth: <20m
Min submersible depth: >1m
5— Type of installation: Vertical (recommend) or as
customer’s requirement
6— Continuous operation

3. Application and Feature 

ZJQ submersible Slurry motor pump is a kind of hydraulic mechanism which motor connects directly with pump. It is used for delivering liquid contained sand, coal cinder solid etc.. The pump can be mainly employed in clearing the mud in lake, river, sea and widening channel etc. it also can be applied to clear out sewage pool; in building site, steel works and power station etc. the pump adopts excellent material, advanced structure, and it is with wide flowing passage & strong delivery ability. The hydraulic parts are wear-resistant. The pump is yet completed with control unit. The pump set consists of main impeller and vice impeller two parts. The main impeller is used for absorbing and delivering solid-liquid mixture, the vice impeller is used for spraying or stirring solid-liquid mixture to help the impeller delivering.

4. Advantage

1— Submersible work Without influence of suction head.
2— No assistant vacuum pump, save your invest
3— No noise, keep the silence of your work station
4— With agitator, no need extra stirring devices , more convenience
for operating.
5— It need not to build pump house.
6— Directly works on the surface of the slurry, with more efficiency
to deliver slurry.
