QG(D) submersible screw pump consists of two parts, screw pump and single phase dry type submersible motor. The connecting part and outlet are made of cast iron, the screw is chrome plated, and the casing is galvanized or coated with paint. In addition, the capacitor and thermal protector are set inside the machine.

On the other hand, our product shows excellent technical performance. The maximum outer diameter range is 101~127mm while the power varies from 0.37kW to 0.75kW. The flow and head ranges are 1.2~1.8m3/h and 20~120m, respectively, and the outlet diameter is G1. Based on these, this machine is used for conditions that require water in daily life and production, such as irrigation for garden and agriculture, water lifting from deep well, pressurized water supply for high place, etc.
