model LPDV_Variable-speed line pump Pump with Inverter-Integrated PM Motor

■Usage ①Cold/hot water circulation ②For various machinery sets ③General water supply ■Features ①Compact and lightweight in-line type allows mounting in the middle of piping, eliminating installation space ②It is possible to disassemble and inspect the bomb with the piping as is. ③The external dimensions of IE3 efficient induction motor (JIS C 4213) are the same as those of the permanent magnet motor (PM motor) and the inverter (built-in), providing low initial cost, energy saving, and space saving. [Energy Saving] ・Use a PM motor with 3000/3600min-1 (2 rateds) that is highly efficient equivalent to IE5. Standard: IEC TS 60034-30-2 (variable speed motor) ・Built-in inverter enables easy adjustment to the rotation speed suitable for the site. Large energy savings are achieved by reducing the performance margin that is inevitable for pump selection. [Space-saving, low initial cost] ・No inverter board installation cost required ・No space required for peripheral equipment (with built-in DC reactor and noise filter, in addition to inverters) [Labor saving] In addition to manual setting, control of discharge pressure, estimated end pressure, flow rate, temperature, etc. is possible. [Compatibility] ・External dimensions equivalent to induction motor ・Easy replacement with the same arrangement and face-to-face dimensions and equivalent performance as existing pumps. [Operability] The following operations can be performed by communication using a dedicated application. ・Operation ON/OFF ・Frequency (rotation speed) setting ・Acceleration time, start frequency setting, etc. (Parameters are already set for each model, and complicated initial setting is not required.)
