الوصف

Design Multistage, frequency controlled 3" submersible pump in jacketed construction for vertical or horizontal installation Application For pumping rainwater and industrial water from boreholes and wells for sprinkling, irrigation and water supply. Equipment/function TWU 3-...-HS-I - Integrated non-return valve - Integrated variable frequency drive with the following functions: - Soft starter - Undervoltage, overvoltage and short-circuit protection - Thermal overload protection of the motor and variable frequency drive - Dry-running protection TWU 3-...-HS-ECP-B - Integrated non-return valve - External variable frequency drive with the following functions: - Soft starter - Undervoltage, overvoltage and short-circuit protection - Thermal overload protection of the motor and variable frequency drive - Constant pressure control - Leakage detection for avoiding excessive switching cycles (pulse) - Dry-running protection with automatic reset - Change of direction of rotation - Settings for max. current and nominal pressure - Pressure indicator on the display - Settings, operating statuses and error messages are shown by LEDs and on the display Constant pressure control function The variable frequency drive controls the speed of the pump based on the nominal pressure. As a result, the submersible pump always delivers a constant pressure.
