| 1.Integral design, spindle and thread are machined out of one single piece,accuracy, rigidity |
5.Bearing supported on each end, sleeve does not contact bushing, no metal scraping, long service life. |
| 2.timing gears deliver torque, stable, low noise |
6.axial balanced rotor, no axial force, low bearing load |
| 3.welded pump body, replaceable bushings,easy maintenance, low cost |
7.with backwards pressure limiting valve, safe, energy efficient |
| 4. Specialized rotor, min.pulse and NPSHr |
8.Medium pressure for the whole structure, broad application |
