WN Dredging Pump is horizontal, single-stage cantilevered structure, which is designed to meet the requirement of the contractor demanding and comprehensive dredging requirement.
WN dredge pump is a single-stage single suction cantilever horizontal centrifugal pump, can replace warman dredge pump, with light weight, good-resistance, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc. They can meet all the requirements from the dredges. Dredge pump are specially designed for mud, sand dredging application in river or sea.WN type warman dredge pump impeller passage is very wide, to continuous pumping gravel or high plastic clay and not happens jam. The minimal amount of wear parts design in these dredge pumps results in reduced wear, long life and lower maintenance which translates into less downtime, significant cost savings and dredging good performance within high efficiency.
200WN - 500WN type warman dredge pump integral by a single pump shell, single stage single suction cantilever horizontal structure, press and gear box of the connection way all can provide two kinds of typical structure, namely take bracket type and pump box and type. Own bracket type lubrication way as the grease lubrication or thin oil lubrication.
600WN - 1000WN type warman dredge pump overall adopts double pump shell, single stage single suction cantilever horizontal structure, bring their own bracket, lubrication way as the forced thin oil lubrication. Double pump shell the safety and reliability of the design makes sheath always can use to close to wear through, and when sheath rupture, pump room will not fill.
● Front release construction, easy to maintain:
The 450WN dredge pump adopts a front-disassembly structure, making maintenance and disassembly straightforward and efficient, ideal for operations requiring reliability and ease of use.
● Impeller release collar, easy disassembly:
The pump is equipped with specialized disassembly tools tailored to each part's features, ensuring smooth maintenance for dredge pumps in various applications.
● Good performance of NPSH:
The excellent NPSH performance of the WN450 dredge pump guarantees strong suction capability, enabling deeper dredging depths, higher dredging concentrations, and optimal performance for dredging pumps in challenging environments.
● Big particles passage:
Designed with a large particle passage, the mud pump can handle heavy-duty tasks effectively, making it suitable for a wide range of dredging applications, including handling sludge.
● Change the speed or diameter of impeller to change working point:
The flexibility to modify the impeller speed or diameter allows this sludge pump to adapt to varying operational needs, ensuring efficiency and performance.
● Wear resistant metal wet-end parts, long service life:
The wear parts of this dredging pump, including the impeller, liner, and front & back liner plates, are crafted from anti-wear cast iron alloy with a hardness exceeding 58HRC. This provides superior impact resistance, high wear resistance, and excellent abrasion resistance, making the mud pump highly durable in demanding conditions.
● High efficiency
● Dredging industries
● Hydraulic Mud Fill
● Sand Suction
