Generals for Wn Dregers Used Gravel and Sand Dredging Pump 
Structure suitable for dredging ship
The structure of 200AWN-500AWN type pumps are single-casing, single-stage, single-suction, cantilever and horizontal. According to the connection with the gear box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.
 
The structure of 600AWN-1000AWN type pumps are double-casing, single-stage, single suction, cantilever and horizontal. It has self-carrying bracket. Lubrication is forced thin oil lubricating. The double-casing design can ensure the liner can work till it is worn out, and if the liner crack, water can not enter into the pump.
 
Easy to Disassembly and Installation Convenient Maintenance
 
AWN type pump adopts front-disassembly structure in favor of easy disassembly and maintenance. Also it is equipped with special disassembly tools for each different part according to each part's features. The standard trapezoidal quadruple thread is adopted to connect the impeller and shaft, which not only transmits strong torque but also is easy to disassembly.
 
Good Performance on NPSH
 
The good NPSH performance of AWN type pump ensures the strong suction ability as well as deeper dredging depth and denser dredging concentration.
 
Good Wear-resistant Performance, Long Service Time of Wet Parts
 
Wet parts of this kind of dredging pump-impeller, liner and front & back liner plate are adapted anti-wear cast iron alloy whose hardness is more than 58HRC, who has both strong anti-attack feature and higher resistance wear and resistance abrasion features.
 
The hardness of new material that is researched and tested successfully by An Pump Machinery Co., Ltd can research 70HRC.
 
Reliable Shaft Sealing Without Leakage
 
The shaft of 200-500AWN dredging pump uses the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing.
 
The shaft of 600-1000 AWN dredging pump adopts spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and one special thread shaft sleeve.
 
The discharge direction of pump can be oriented in any direction of 360 degrees.
 
This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion resistance
 
Drive types includes V-belts driven, flexible coupling driven, gear box driven, hydraulic coupler driven, variable frequency driven, thyristor speed control etc.
 
AMG/AMGH gravel Mud Pump are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries
in mining, explosive sludge in metal melting, grudging in dredger and course of river, and other fields. Type AMGH pumps are of high head ones

Tips for sand pump installation
 Please take note as below when install the sand pump:
1. The preformed hole on the foundation should be poured as the pump installation drawing.
2. The installation level should meet the demand of the allowed vacuum suction height. The foundation should be in horizontal and stable condition, to make sure the rotation of the driver machinery same with the pump in the direction.
3. When connect by coupling, must make sure the pump and driver shaft center  should be in a straight line.
4. If belt connection, the shaft center should be in parallel.
5. The sand pump suction pipe should be sealed well, and try to less the quantity of the elbow and check valve. When fill water, exhausted the air. It should be no any air when operate. We need to keep the suction pipe slopes up slightly, and then connect with the pump inlet.
