DOQZ Submersible Slurry Pumps are designed by the performance of DOH Heavy Duty Slurry Pump, DOSC Single Case Slurry Pump, DOV Vertical Slurry Pump, DOZJL High Efficient Vertical Slurry Pump. 

Parameters and Pump Selection
DOQZ Submersible Slurry Pumps are designed by the performance of DOH Heavy Duty Slurry Pump, DOSC Single Case Slurry Pump, DOV Vertical Slurry Pump, DOZJL High Efficient Vertical Slurry Pump. They are heavy duty all chrome wet end coupled with a motor for high erosive demanding applications.
“DOQZ” Submersible Slurry Pump are designed with all chrome wet end powered by a submersible motor to achieve rugged, dependable solids handling capability at lower cost. 
Submersible Slurry Pumps are designed pumping slurry from sump or pits, where the depth is deep that sump slurry pumps can be reached, “DOQZ” are designed with the performance of “DOV”, “DOSC”, “DOS”, “DOZJL” Single-case. 
“DOZQ” Submersible Slurry pumps are combined with high efficiency, large working capacity, high head, large particle pass both in slurry pumping and sand dredging.
Submersible motors for slurry pumps are all Class H and can are designed for handling heavy duty slurries with up to 1.7 specific gravity. Low operating RPM promotes low wear rates and extended component life. 
High efficiency agitator can be fitted to the impeller eye allowing the pump to agitate high concentrations of solids.  
Impeller, casing, back liner, agitator are all with high chrome material which are highly used in abrasive working condition. 
Vertical Froth Slurry Pumps are designed to increase the pump ability of frothy slurry, which can reduce normal slurry pump working performance and increase wear on pump parts. 
The operation principle of “DOF” Vertical Slurry Pump is similar to that of hydrocyclone separation, rotating impeller and tangential inlet can increase the vortex which separate air from the slurry, therefore, “DOF” Vertical Froth Pump can result in more efficient pumping at higher capacities and a smooth operation. 
Vertical Froth Pump are designed feature of: Integrated unit for layout flexibility, Smooth operation of the open vortex created in the Vertical and vertical “wet end” inlet prevents air locking, Cantilever design does not require submerged bearings or shaft seals, 
Bearing assembly with double protection sealing arrangement to prevent ingress of slurry, and wear parts are available in a variety of different materials, for standard pumps are supplied with parts in wear resistant Natural Rubber or High Chrome iron alloy, with a nominal hardness of 600 BHN.
Other war part materials are available. The wear parts have large material sections for extra long wear life and are designed for the toughest applications.
Parts in different materials are fully interchangeable and can be combined for optimum life.
