Product Description
The WN type mud pump can achieve various pump performance adjustments by changing the impeller speed or the diameter of the mud pump impeller to change the pump head at the same flow rate in advance. Good wear resistance and long service life of overcurrent components. In the overcurrent components of the WN mud pump, the impeller, sheath, and front and rear guard plates (wear-resistant lining plates) are made of wear-resistant alloy cast iron with a hardness of not less than 58HRC, which not only has strong impact resistance but also high abrasion resistance; The A31 material successfully developed by the company has a hardness of up to 70HRC. In the product design process, full consideration is given to the matching of the service life between components, and the replacement cycle of wear-resistant parts is basically the same, reducing maintenance and replacement costs. The hydraulic loss is small, the efficiency is high, and the power consumption is low. Due to the hydraulic model used, the efficiency level of the mud pump is high. The efficiency level of WN type mud pumps is on average 2-3 percentage points higher than that of imported mud pumps. In this way, lower fuel consumption can be achieved with the same output. The shaft seal is reliable and leak free. The 200WN-500WN dredging pump shaft adopts mechanical seal, packing seal or mechanical seal. The shaft seal of the 600WN-1000WN dredging pump adopts a spiral sleeve L-shaped rubber sealing device, which consists of 3 L-shaped sealing rings and 1 shaft sleeve with special threads. The electric turning mechanism saves time and effort. The 700WN-1000WN dredging pump can be equipped with an electric turning mechanism, which can drive the pump shaft to achieve forward and reverse rotation. When disassembling and assembling the impeller, it not only saves time but also reduces the workload of the operator. Performance parameter table of WN (Q) series dredging pumps (for preliminary selection only) Yuzhou Longde Pump Co., Ltd. is a pump product manufacturing company that integrates design, casting, precision machining, and scientific research.
Installation & Maintenance Notes
- 1 Before first start-up, check the motor rotation direction and make sure it matches the pump direction.
- 2 Every time before starting, turn the shaft by hand through one full revolution — it must turn freely without jamming or rubbing.
- 3 Keep a 2–3 mm clearance at the coupling.
- 4 Grease the bearings regularly every shift.

YZ Type Slurry Pump
YZ type submersible slurry pump is a vertical single-stage single suction cantilever centrifugal pump structure, with a semi open impeller and stirring blades extending from the suction edge of the impeller. This series of pumps is mainly used in industries such as environmental protection, municipal engineering, thermal power plants, gas coking plants, refineries, steel mills, mining, papermaking, cement plants, food plants, printing and dyeing to extract concentrated liquids, heavy oils, oil residues, polluted liquids, mud, mortar, quicksand, and flowing sludge from urban sewage channels, as well as fluids containing mud and sand residues and corrosive liquids. It can also transport high-temperature (480 ℃) kerosene, crude oil, asphalt, oil residue and other materials
Hydraulic Sand Pump
Selection of hydraulic sediment pump: 1. Select the pump type according to the actual flow rate, head, and delivery distance required for the operating conditions, and calculate the required hydraulic power based on the motor power of the pump type; 2. The hydraulic power calculated based on the selected pump type matches the hydraulic oil station that can meet the hydraulic power requirements; 3. Calculate the actual output power of the excavator hydraulic system and select the appropriate pump type; 4. Customized modifications can also be made according to specific customer requirements (such as screw type, rake suction type, bucket wheel type). Drive mode: hydraulic drive Material used: high chromium wear-resistant alloy Additional mixing: dual agitator type, single twist cage
