Horizontal Centrifugal Pump ZL Series
- Diameter range: DN25-DN400mm
- Flow range: 12-5040m3/ hr
- Head range: 5-118m
- Speed: 300-3800r/min
- Motor power: 15-1200KW
- Working temperature: ≤80 ℃
ZL series horizontal centrifugal pumps are suitable for conveying slurry with fine particles, as well as low concentration or corrosive slurry.
For actual operation, we recommend that the pumped slurry has a concentration of no more than 30%. This pump series can also transport high concentration and low abrasion slurry such as fly ash, plaster, paper mill wastes and liquors. The ZL series pumps are widely used in mineral processing, agricultural waste suction, waste water treatment, paper manufacturing and other industries.
Structure Features- The pump casing has a replaceable abrasion-resistant metal liner or rubber liner. The impeller is made of a wear resistant metal or rubber material.
- The pump's outlet position is arranged at an interval of 45 degrees in order to facilitate different installation needs.
- The bearing assembly is movable, offering convenience to users for adjusting the clearance between the impeller and front liner insert. This also maintains the transportation efficiency by narrowing the impeller clearance, even if the pump is worn.
Model selection table (clear water performance)
ZL series pump wet ends are usually made of a high chromium wear-resistant alloy. If it is used for conveying corrosive slurry, we will replace the liner material with rubber liner to form a ZLR series pump.
In addition, if the conveyed medium is in high concentrations, you can choose the large type ZM-10×8T pump or ZM-10×8R pump.
