China high quality centrifugal slurry pumps/sand dredge pump
WN series centrifugal sand dredge pumps for the river or marine ship or dredger are the series products introduced from abroad,and it could be installed on the dredger or barges for pumping the slurry.
With the strength of robust structure design with front disassembly and easy installation and maintain, super dredging performance, suitable to match with dredging ship's requirements in the river or sea.
Pump structure
The structure of 200WN-500WN type dredge pump is 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 pump is 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.
Pump features
1) The whole construction is suitable for dredging ship
2) Easy disassembly and Installation, Convenient Maintenance
3) Dredging performance is excellent
4) Good NPSH WN Dredging pump has good NPSH which ensures the strong suction ability as well as deeper dredge depth and denser dredged mud.
5) The wide running passage of impeller of WN Dredign pump and the dredging pump's strong passing capacity make sure of the good performance of dredger. While it can deliver the particles or high plastic.
6) Shaft seal: gland packing seal; mechanical seal; packing & expeller seal. Reliable sealing without leakage.
7) Material: Ni-alloy or high chromiun wear-resistant alloy.
8) Single suction, cantilevered horizontal centrifugal device with single casing.
