Excellent dredging performance of SWN Series Dredging Pump:

1. Good cavitation performance: SWN mud pump has good cavitation performance to ensure the strong suction capacity of the mud pump, and at the same time, it can achieve greater digging depth and higher inhalable concentration.
2. Strong flow capacity and wide applicability: SWN type mud pump has a large impeller channel width, and the good passing capacity of the mud pump itself is a good guarantee for the performance range of the dredger, which can continuously pump gravel or high plastic clay without A blockage occurs.
3. The performance curve drops sharply: The flow and lift curves of the SWN mud pump drop sharply, which makes the
mud pump more adaptable to the change in displacement distance.
4. Various configurations of pump performance can be realized: SWN mud pump can change the pump head under the same flow by changing the speed of the impeller or changing the diameter of the impeller of the mud pump.
Good wear resistance, long life of overcurrent parts:
1. Among the overcurrent parts of the SWN mud pump, the impeller, sheath, and front and rear guard plates (wear-resistant lining plates) are made of strong wear-resistant alloy cast iron with a hardness of not less than 58HRC. It has a high degree of anti-wear performance.
2. In the process of product design, the service life matching of components is fully considered, and the replacement cycle of wear-resistant parts is basically the same, which reduces maintenance and replacement costs.
Small hydraulic loss, high efficiency, and low power consumption: The mud pump has a high level of efficiency due to the advanced hydraulic model. The efficiency level of SWN mud pumps is on average 2-3 percentage points higher than that of imported mud pumps. In this way, at the same output, lower fuel consumption can be achieved.
Reliable shaft seal, no leakage:
1.200SWN-500SWN dredging pump shaft seal adopts mechanical seal or packing seal or mechanical seal plus packing compound seal.
2. The shaft seal of the 600SWN(Q)-1000SWN(Q) type dredging pump adopts a screw sleeve L-shaped rubber sealing the device, which consists of 3 L-shaped sealing rings and a shaft sleeve with a special thread.

Model SWN Series

Applications of SWN Series Dredging Pump
Used in rivers, port dredging, dredging, dredging, reclamation of the sea, reclamation of the sea for the construction of ports, underwater mining, underwater sand mining, and other working conditions that require anti-abrasion.

Features of SWN Series Dredging Pump
The overall structure is good for marine use:
1. Simple and reliable structure: 200SWN-500SWN, 600SWNQ-1000SWNQ dredging pumps adopt a single pump casing, single-stage single-suction cantilever horizontal structure as a whole, and two typical structures can be provided according to the connection method with the gearbox, that is, the self-contained The bracket type is integrated with the pump box. The self-contained bracket-type lubrication method is grease lubrication or thin oil lubrication.
2. Easy disassembly and assembly, convenient maintenance: SWN dredging pump adopts a front disassembly structure, which is easy to assemble and disassemble to facilitate maintenance; at the same time, according to the structural characteristics of each component, it is equipped with special disassembly tools to facilitate disassembly and assembly.
The standard four-head trapezoidal thread connection is adopted between the impeller and the shaft, which can transmit strong torque and facilitate disassembly and assembly; at the same time, an impeller disassembly ring is provided at the shaft sleeve to facilitate the disassembly of the impeller.
