There is a common shaft between the pump and motor. The pump & motor unit is of close coupled construction and the double casing design provides effective water flowing around the motor casing. Perfect isolation between these two is achieved with the help of a mechanical seal make up of tungsten carbide which is protected and covered by leap seals. The double sealing arrangement keeps the motor away from the liquid being pumped and high-grade corrosion resistance & abrasion resistance material is being used. All material used is eco - friendly.
