Fully meet the requirements of dredgers for mud pumps.

The dredging pump system is mainly composed of a pump head, a reduction box, a flexible coupling, a marine transmission and a monitoring system.

The impeller, front guard plate and rear guard plate of the mud pump over-current component are all made of strong anti-wear alloy cast iron. The hardness of the material is more than 58HRC. The pump body is made of wear-resistant alloy steel with excellent anti-wear and pressure.

The structure is simple, easy to disassemble and repair, reduce the workload, reduce staffing and improve economic efficiency.

At the same time, we can use different metal materials to meet the requirements of use according to the requirements of users and different media conditions.

Applicable working conditions:

It is suitable for dredging and bucket wheel type ship dredging conditions, and is widely used in dredging, dredging and dredging projects in rivers, lakes, docks and coastal areas.

Product efficiency and energy saving are significant. Strong suction capacity, deep digging and high dredging concentration.

Strong flow capacity, continuous pumping of gravel, clay and high plastic clay.

It has strong matching and can be equipped with diesel engine and generator.

Performance range:

Dischargerange: 100~850mm

Flowrange:180~1600m3/h

Head range: 20 ~ 90m

Horizontal centrifugal pump are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.

common uses include water, sewage, agriculture, petroleum and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering. A centrifugal fan is commonly used to implement an air handling unit or vacuum cleaner. The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy. Working of a centrifugal pump

let us understand in detail, how a centrifugal pump works. Centrifugal pumps are used to induce flow or raise a liquid from a low level to a high level. These pumps work on a very simple mechanism. A centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. The two main parts that are responsible for the conversion of energy are the impeller and the casing. The impeller is the rotating part of the pump and the casing is the airtight passage which surrounds the impeller. In a centrifugal pump, fluid enters into the casing, falls on the impeller blades at the eye of the impeller, and is whirled tangentially and radially outward until it leaves the impeller into the diffuser part of the casing. While passing through the impeller, the fluid is gaining both velocity and pressure.
