Vertical Mixed Flow Pump
- Features
-
- The installation area is small.
- The installation method of the pump can be selected as one-phase or two-phase type.
- There is no need for a vacuum pump, and there is little risk of motor flooding.
- Low center of gravity of the product designed to minimize vibration and noise.
- The vortex prevention plate is attached to the suction pipe, so there is little vibration caused by the vortex.
- It is designed and manufactured for easy maintenance.
- It is possible to select submersible bearings suitable for the site conditions.
- Self-lubrication : Submersible Bearing
- Fresh water lubrication : Rubber Bearing
- Grease lubrication : Metal Bearing
