TDE series vertical single-stage intelligent variable frequency pump (Hereafter as TDE series or pump) adopt an intelligent variable frequency controller in TD series single-stage inline centrifugal pump. It can realize constant pressure, constant temperature, constant pressure difference and other smart control functions by connecting pressure and temperature sensor.TDE series are energy-saving, low noise, intelligent, environmentally friendly with compact structure, beautiful appearance,high reliability and easy maintenance convenience. Pressure or temperature sensors and other accessories are not in TDE factory configuration. Users need to configure it according to needs.

The top of TDE series is designed as a pull-out available form, which enables to repair the pump without affecting the pipeline system.
