With single (double) flow channel or single (double) blade structure and the hydraulic without clogging designing, WL series vertical sewage pumps have the following advantages: Good flow performance, smooth running, small vibration, perfect reliability, easy to install and operate and automatically control. Using the imported bearing, the mechanical seal and the stainless steel shaft makes the pumps with better performance. Flow Capacity: 20---10000 m3/h Head: 6— 54 m Motor Power: 4---1800 kW Discharge Diameter: 65— 800 mm Particle: 25— 300 mm

Application Scope
The pump is widely used in the water supply and drainage of city, the conveying and discharge of sewage, mud, manure, mortar, pulp and so on in the industrial enterprises and commerce. It also can be used as the circulation pump and the agriculture irrigation pump. pH: 5-9, temperature under 45º C, the impurity content (the ratio of weight) less than 25%.

The long shaft is used to connect with pump. (The limiting speed is 1500 r/min). (2). If the center of pump volute is above the water surface (within the suction scope), the vacuum device can be supplied for the customer. (3). All the vertical pumps are explosion-safe types. (4). For the ordinary pump with the discharge diameter ranging from 65mm to 350mm, the base-plate with bend is adopted; For the vertical pump with the discharge diameter more than 350mm, the base-plate with straight pipe is adopted; For the base-plate of the rest pumps, require the customer to indicate. (5). For the high-pressure vertical, the packing sealing and the base-plate with straight pipe are adopted.
