EIS-Industrie DP. Dredge Pump

are a horizontal, single-stage, cantilevered structure, which are designed to meet the requirement of comprehensive dredging requirement.
The ESP DP pumps have excellent wear resistance and high efficiency, easy to maintain and improve the output of the operation.

The structure is simple and reliable

ESP DP-200 ~ ESP DP-500 dredge pump using a whole single pump shell, single-stage single-suction structure, according to the connection with the gear box can provide two typical structure, that is, comes with bracket and pump box combined. Bracket-type lubrication comes with grease lubrication or thin oil lubrication.

ESP DP-600 ~ ESP DP-1000 dredge pump using whole double pump shell, single-stage single-suction cantilever horizontal structure, comes with brackets, forced oil lubrication. The double pump casing can make sure that the volute can be used until close to wear, and the pump chamber will not enter the water when the volute is broken.

Easy disassembly, easy maintenance

ESP DP type dredging pump used front demolition structure, easy disassembly, maintenance; at the same time offer special tools for disassembly of various components

Impeller and shaft use four-headed trapezoidal screw connection, can pass a strong torque, and easy disassembly at the same time, there is an impeller removal ring on sleeve to removal the impeller easily

ESP DP type dredging pump has a good cavitation performance to ensure bigger suction ability, while achieving greater dug depth and higher respirable concentrations.

ESP DP type impeller flow channel is width, can, continuously pump gravel or high plastic clay without clogging.

ESP DP type pump can change the impeller speed, or change the diameter of the pump impeller to achieve the same flow pump with head changes.

Good wear resistance, long using life wet parts.
Impeller, volute, front and back liner (wear-resisting lining) using anti-wear alloy cast iron with hardness of not less than 58HRC, have strong impact resistance and of anti-wear properties; The company successfully developed A31 material, hardness can reach 70HRC.

In the product design process, the service life of all the parts is matched with each other, and the replacement period of wear-resistant parts is basically the same, which reduces the maintenance and replacement cost.

Water loss is small, high efficiency, low power consumption
Due to the use of advanced hydraulic models, the efficiency of the pump is high.

Shaft seal is reliable and no leakage

ESP DP-200 ~ ESP DP-500 dredge pump shaft seal using mechanical seal, packing seal or mechanical seal plus packing compound seal.

ESP DP-600 ~ ESP DP-1000 dredge pump shaft seal using screw-type L-shaped rubber seal device, the seal device include three L-shaped rings and a special thread with the sleeve composition
