QY Series Oil-immersed Large Submersible Electric Pump for Water Transfer

Description :

1. QY series oil-immersed submersible pump consists of three parts: water pump, seal and motor. It has single-stage or multi-stage centrifugal and mixed flow impellers, radial guide vane structure and axial flow impeller space guide vane structure; between water pump and motor An integral mechanical seal or a double-ended mechanical seal is used as a dynamic seal; an "O" type oil-resistant rubber sealing ring is used as a static seal at each fixed stop. 2. The electric pump rotating shaft is hard chromium plated, which can effectively improve the wear resistance and corrosion resistance of the shaft and facilitate the maintenance and disassembly of the impeller.

3. The electric pump motor of 4KW and below is equipped with a thermal protector, which can automatically disconnect the power supply to protect the motor under abnormal conditions such as phase loss and overload of the electric pump. Electric pumps of 7.5KW and above 5.5KW need to be equipped with additional motor protection devices.

Characteristics :

This series of electric pumps are widely used in engineering, farmland, mining, construction sites, municipal environmental protection and other places. They can pump liquids that do not contain fiber, paper, sediment and other solid particles, such as well water, river ponds and other clean water. They are ideal for agricultural drainage and irrigation, It is an ideal pumping equipment for water tower water supply and mine drainage, but it is not suitable for use in explosion-proof requirements.

Applications :

Garden sprinkler irrigation

fire booster

Long distance transportation

home booster

Pressurized water supply for industrial and urban drainage high-rise buildings
