Rotor completion:
Rotor part can be operated in reverse rotation.
Double suction impellor with optimal design minimizes axial force;
Fine casting of impellor with excellent hydraulic performance is anti-cavitation and high efficiency.
Shorter shaft length designed to have better rigidity without vibration.
Shaft is no contact with liquid so as to avoid corrosion to ensure longer service life.
Double volute casing:
Extend bearings life by reduced radial force.
Bearings:
Two sides of bearings are high purity, with steady performance and low vibration.
Bearings are grease lubrication.
Mechanical seal:
Mechanical seal or gland packing with auxiliary system for options.
Easy maintenance:
Disassemble pump without moving inlet and outlet pipe line by structure of pump suction and discharge below and vertical to pump shaft line;
Integral rotor completion is lifted fit-in.
