High-Speed Thruster Cold Propeller Blade, Submersible Thruster Glass Fiber Propeller, Submersible Propulsion Blade
Duwan Environmental's QJB Low-Speed Flow Promoter Leak Protection Function is designed to detect water leakage inside the submerged mixer. When water leakage occurs within the mixer, it will trigger corresponding alarm and control signals.
Low-speed flow inducer motor overheating protection is specifically designed to monitor the temperature of the stator winding inside the submersible mixer. Should an abnormal temperature occur within the stator of the mixer, the electric control unit will trigger the corresponding alarm and control signals, or automatically shut off power, to prevent the stator winding from burning out and facilitate timely maintenance and handling by staff.

Jiangsu Du'an Environmental Protection QJB Submersible Propeller DriverPolyurethane impeller Polyurethane impeller, with a long service life, reduces the frequency of replacement for cast iron and rubber impeller covers, making it your ideal choice. Polyurethane, also known as polyurethane carboxylate, is a high molecular polymer material that lies between plastic and rubber. It possesses both the high strength of plastic and the high elasticity of rubber, making it a new, wear-resistant material with excellent comprehensive properties. It boasts many superior characteristics, including high wear resistance, ranking first among synthetic materials, even surpassing some alloy steels. Using polyurethane as the lining for equipment, its service life is four times longer than cast iron and four times that of nitrile rubber, and eight times that of natural rubber. The Shore hardness of polyurethane is17-97 range, at 80-90, wear resistance.
Fiberglass propeller features: Long service life, rarely contacts hard objects, not prone to breakage or cracking, and excellent mechanical properties.
