Description of Double-walled Dredge Pump
Our Double-walled Dredge Pump has high efficiency, significant energy saving, super suction and over-flow capability.It can be equipped with diesel engines or be equipped with motor driven directly. Our Double-walled Dredge Pump has varieties of advantages,such as working stability, little vibration, low noise and low hydraulic loss, high efficiency, low fuel consumption and small size, light weight, simple structure, easy maintenance.
It is also fitted with external pump housing which allows the internal pump housing to be constructed from extremely wear-resistant material.This also means that a smaller part of the wall thickness is needed for mechanical strength and a larger part is available for wear losses. The outer housing also offers optimal security. In case of fracture of the internal pump housing, the outer housing prevents flooding of the pump room.
Usage:Slurry mud
Fuel:Diesel
Power:Hydraulic
Pressure:High pressure
Standard:Nonstandard
Theory:Centrifugal pump
The characteristics of Double-walled Dredge Pump are:
1.Long working life in abrasive conditions
2.Efficiency up to 92% (as measured in practice) resulting in lower fuel consumption at unchanged production
3.Reduced and more even wear, resulting in longer lifetime of wear parts
4.Better performance as a result of the low net positive
5.Suction head required (NPSHR)
6. Highly versatile application due to steep flow head ratio curve
7.Limited influence of wear on pump performance
