L series slurry pumps
L series slurry pumps are cantilever, centrifugal slurry pumps. It adopts horizontal and vertical axial casing structure, and the inner lining could be hard alloy or rubber, which has good wear resistance, corrosion resistance and high reliability. The product has the characteristics of reasonable structure, reliable operation and long life. Especially suitable for low concentration and low abrasion slurries. The shaft seal of this pump adopts two types which are packing seal and centrifugal seal.
Overall performance and advantages of L series slurry pump
1. This type of pump has high speed, small size, compact structure, saves installation space and reduces construction costs.
2. The pump liner has a replaceable wear-resistant metal liner or rubber liner, and the impeller is made of wear-resistant metal or rubber.
3. This series slurry pump has the same structural advantages as the HH/AH series, cylindrical structure bearing assembly, adjustable impeller, outlet direction can be rotated and installed at 8 angles, etc.
4. The pump is made of special material developed by our company's advanced technology, which ranks first even in the international market, and the service life of wearing parts is longer than before
5.
Ensure that important technical data for operation and maintenance are provided to users timely according to the contract. Experienced engineers and technicians are selected to provide technical services on-site in time to guide installation and commissioning in accordance with the the contract or user requirements.
Application Fields and technical data
L series slurry pumps are mainly used in mining, metallurgy, municipal, electric power, coal, petroleum, chemical, building materials and other industries. The main indicators are as follows:
Caliber: 20-650mm
Flow rate: 3-12600m3/h
