QD Multistage Water Pump Features

1.Multistage pump compact structure, small size,beautiful appearance, its vertical structure decided small installation area,its centre of gravity overlap center of pump foot, thus enhancing the runningstability and service life of the pump.

2. The multistage pump can meet differentrequirements by increasing or decreasing the pump stages combining cuttingimpeller diameter, without changing the installation area, and this is themultistage pump special own.

3. Pump rotor is provided with low wind ability toachieve smooth operation, little vibration, low noise and long service life .

4. According to the needs, the suction and dischargenozzles can be installed into the same direction, several different directionsin order to meet different connection.

5. Motor plus outer rain cover, pump can be placedin the outdoor use, cancel the pump room, save construction cost.
