Product Details

Feature

 Double casing construction. It has a character of high efficiency, wear-resistance, stable performance and excellent interchangeability. The material of the liner and impeller is made of wear-resistant metal or rubber, and the discharge branch can be positioned at 8 different positions at an interval of. The pumps may be installed in multiple stages in series, and may be driven by a belt or a direct coupling. The seal of the shaft may be adoptable of a gland seal, expeller seal, or mechanical seal. The pump should be rotated counterclockwise, viewing from the driving end.

 

Application

The pumps are suitable for delivering middle, low head duty in metallurgical, mining, coal, and power industries, etc, for example, delivering slurry in mining, metallurgical, power plant, steel mill, and chemical industries, etc.
