Product Description

**0QJ series submersible pumps TECHNICAL FEATURES The series QJ pumps are manufactured to be coupled to NEMA standard motors. The series QJ pumps are improved in the design especially for the impeller and diffuser, offering the following advantages: -High head for single stage impeller and diffuser than the usual one so that similar performance is given by reduced number of stages. -Axial thrust load on the motor shaft is obviously reduced leading to increased average life of the motor. -The built-in non-return valve is easy to remove and to inspect. MATERRIALS -Casing both of pump and motor, pump shaft: stainless steel AISI **4. -Outlet and inlet: bronze -Impeller and diffuser, non-return valve: thermoplastic resin PPO INTERNATIONAL STANDARD IEC ******1Household and similar electrical appliances-safety The new range of 3.5″, 4″, 5″, 6″ deep well submersible pumps are designed for easy of fitting. Their particular features positively improve the traditional. The pumps are widely used for shallow and deep well.
