ZJQ Submersible Sludge Pump
Product Description
The ZJQ submersible sludge pump is designed for hydraulic work, where the motor and the pump are coaxially submerged in medium. When the pump shaft is driven by the motor shaft during operation, the energy is transferred to the slurry medium, which creates a certain flow rate, driving the solids to flow and fully realizing slurry transportation.
The overflow features of the pump are constructed from high alloy, wear-resistant material, guaranteeing an extended work life and accommodation of large flow volumes. Applications include conveying media (including sludge, ore slurry, coal slurry, and sandstones containing big solid particles), pumping sand, and tailing slurry, iron, and sand ore, and sediment in sewage treatment work, among others.
In addition to the main impeller, the bottom of the sludge pump includes a set of agitation impellers that can work the deposited sludge into turbulent flow, increasing the concentration without need of an auxiliary device. The unique sealing device can effectively balance the pressure inside and outside of the oil chamber for maximum protection. The motor was designed with many safety features including, protection from overheating, water inlet detecting projections, and an ability to operate safely for long periods of time in harsh working conditions. The slurry agitator is optional to increase pumping efficiency.
Product Features
Main Application
