Centrifugal Pump: 1. Fully open, three-blade impeller, large flow channel, strong performance without clogging. 2. Wear-resistant linings at the suction and discharge ends of the impeller are used to protect the eddy current casing. 3. The new protective cover design makes it easier to disassemble. 4. Brand new chassis design, stronger and more convenient for coupling adjustment. Fan Pump: 1. The replaceable wear-resistant mouth ring protects the pump body from being worn, and ensures that the fluid flows smoothly to the impeller to improve efficiency; 2. The blades of the double-suction impeller are divided radially and arranged in staggered and inclined directions, which have the characteristics of high efficiency and low cavitation margin; 3. Heavy-duty horizontally split pump body. The inlet and outlet flanges are located in the lower pump body. The inspection, maintenance and replacement of rotor parts can be carried out without dismantling the piping system and the motor.
