Naipu Vertical Centrifugal Sump Pump with Rubber or Metal Liner

Vertical Centrifugal Sump Water Pump with Rubber or Metal LinerHigh Capacity Submersible Water Vertical Centrifugal Pump With Rubber Liner   1. Vertical type single stage centrifugal slurry pumps2. Application for sump pumping, Single stage pumpNP-SP(R) centrifugal slurry pumps are mainly used to pump high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones and etc.Sump pump specification:D: 40-200 mmQ: 17-891 mmH: 4-37 mSlurry Pump Function: 1. Wear-resistant metal, the impeller selection of wear-resistant metal or rubber material.2. NP-SP(R) type sump pump parts, immersed in liquid rubber lining.3. Different length of the pump drive shaft or inhaled could be selected4. V-belt drive, direct drive, and flexible coupling.5. Bearing to lubricate oils.6.  use of variable speed, the best condition in the pump operation, long service life, run- effective,meet many bad transportation conditions. Vertical Slurry Pump Performance Parameter:TypeAllowable Max.
