1. Large flow capacity achieved with almost no vibration or noise by use of axial and mix flow design. 2. Robust construction and compact design with a dry motor, double mechanical seals and impeller flow guide vane for high efficiency. 3. Easy handling, energy saving and low maintenance. 4. High efficiency motor directly connects to impeller to achieve best energy savings. 5. Pump manufactured with heavy duty housing, cable leads are isolated by hardened epoxy for water proofing, double mechanical seals. 6. Shaft and impeller are precisely balanced for quiet and long life performance. 7. Casted albc3 meterial ( aluminum bronze ) impeller, it has a great abrasion and corrosion resistance.
