Features
1.Pass ATEX, CCS and IECEx certification
2.Pump and motor are completely immersed in medium, which can continuously cool the pump.
3.The pump is of vertical structure, which makes it operate more steadily with long service life.
4.The motor is designed based on inverter technologies.
5.Self-balancing design is employed, which makes radial force and axial force automatically balance during operation of whole pump, and extends the service life of bearings.
