Attributes:

one. dredge pump ideal for dredging ship:

The composition of 200WN-500WN type pumps are solitary-casing, solitary-phase, one-suction, cantilever and horizontal. In accordance to the link with the equipment box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or skinny oil.

The composition of 600WN-1000WN kind pumps are double-casing, single-stage, solitary suction, cantilever and horizontal. It has self-carrying bracket. Lubrication is forced slim oil lubricating. The double-casing design and style can make certain the liner can function till it is worn out, and if the liner crack, drinking water can not enter into the pump.

 

two. Straightforward to Disassembly and Set up, Convenient Routine maintenance:

WN variety pump adopts front-disassembly structure in favor of simple disassembly and routine maintenance. Also it is geared up with particular disassembly equipment for every different portion in accordance to every single parts attributes.

The standard trapezoidal quadruple thread is adopted to hook up the impeller and shaft, which not only transmits sturdy torque but also is simple to disassembly.

 

three. Excellent Functionality on NPSH:

The excellent NPSH performance of WN type pump guarantees the strong suction capacity as effectively as further dredging depth and denser dredging focus.

 

4. Very good Use-resistant Performance, Prolonged Provider Time of Moist Areas:

Wet parts of this variety of dredging pump-impeller, liner and entrance & back liner plate are tailored anti-put on cast iron alloy whose hardness is more than 58HRC, who has equally sturdy anti-assault feature and greater resistance wear and resistance abrasion functions.

 

five. Trustworthy Shaft Sealing Without having Leakage:

The shaft of 200-500WN dredging pump makes use of the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing.

The shaft of 600-one thousand WN dredging pump adopts spiral sleeve L (form) rubber sealing device that is composed of 3 L sealing ring and a single special thread shaft sleeve
