Multistage Pump Introduction
Multi-stage section centrifugal pump, the excellent hydraulic models are high-efficiency, energy-saving, and have wide performance range, operating safety & steady, low noise, long life and installing & repairing is very convenient etc. It can deliver heat water, oil, corrosive or wear albe medium by changing the material, seal or adding cooling system.
Multi stage pump can deliver the neuter mineral water which solid particles percent≤ 1.5%(solid Dia, < 0.5mm) and others
Temperature of the liquid is ≤ 80°C. It is suitable for steel works, mines, cities projects etc. This kind pump can deliver the corrosive liquid without solid particle, which temperature is from -20°C-150°C. The multi stage pump deliver oil or oil products without solid grain, viscosity ≤ 120ct, range of temperature is from -20°C to 150°C
Applications List
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.
