EL Electric Submersible Dredge Pump are designed with all chrome wet end powered by a submersible motor to achieve rugged, dependable solids handling capability at lower cost.
1. Submersible Dredge Pumps are designed pumping sand/slurry from sump or pits, where the depth is deep that sump Dredge Pumps can not be reached, “EL” Submersible Dredge Pump are designed with the performance of “DOV”, “DOSC”, “DOS”, “DOZJL” Single-case.
2. “EL” Submersible Dredge Pumps are combined with high efficiency, large working capacity, high head, large particle pass both in Dredge Pumping and sand dredging.
3. Submersible motors for Dredge Pumps are all Class H and can are designed for handling heavy duty slurry/sand with up to 1.7 specific gravity. Low operating RPM promotes low wear rates and extended component life.
4. High efficiency agitator can be fitted to the impeller eye allowing the pump to agitate high concentrations of solids.
5. Impeller, casing, back liner, agitator are all with high chrome material which are highly used in abrasive working condition.

Product Feature
1. Submersible Motor
--The motor is submerged in the fluid or slurry to work for sand pumping.
--Motor is designed for slurry applications.
--Optional Motor Cooling Loop
--Standard operating depth 30 meters and customized for depth up to 120 meters.
2. Mechanical Seal
--Mechanical Seal works for avoid water or slurry into the motor.
--Balance the pressure to stop water or slurry into the motor and the pump working pressure.
--Bear the pressure from the standard atmospheric pressure and the depth of suction pressure.
3. Adapter Plate
--Adapter Plate is design for connection between pump engine and pump casing.
--Casting Steel or cast iron material to support pump pressure.
4. Back Liner
--High Chrome material or customized high abrasive material for back liner.
--Back liner is bolted to allow for easy maintenance.
--Thick back liner design for high efficiency.
--Connected with adapter plate and pump casing.
5. Casing
--Heavy duty casing design to minimize internal velocities.
--High chrome material standard or customized material for long wearing life.
--Simple bolted with adapted plate, back liner.
6. Impeller
--Unique design of impeller for large capacity and long distance transportation.
---High chrome material standard or customized material for long wearing life.
--The gap design of impeller to make sure large particle pass.
--Impeller pump out vanes reduce gland pressure and improve efficiency with reduced circulation at inlet side.
7. Agitator
--Attached directly on the pump shaft under the pump impeller.
--Rotating the sand slurry with the fluid to improve sand slurry pumping efficiency.
---High chrome material standard or customized material for long wearing life.
8. Extra Excavator
--Extra Excavator hEL-Ps pump with slurry and/or sand rotating.
--Slower rotating speed to 78 RPM.
