6 Inch River Sand Pumping Machine 250 WN With Reliable Shaft Sealing No Leakag
Product Introduction of dredge pump
WN dredge pump is a new type of sludge pump researched & manufactured by our factory,aiming at rivers and seas out of repair.WN pump is a single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistant, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc.It throughout meets requirements of the dredge to dredging pumps
Features
1. Structure suitable for dredging ship:
The structure of 200WN-500WN 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 600WN-1000WN 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.
2. Easy to Disassembly and Installation, Convenient Maintenance:
WN 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.
3. Good Performance on NPSH:
The good NPSH performance of WN type pump ensures the strong
suction ability as well as deeper dredging depth and denser
dredging concentration.
4. 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 A31 material that is researched and
tested successfully by Kingda can research 70HRC.
5. Reliable Shaft Sealing Without Leakage
