Operation
The compact and silent pressure group. It is ideal for domestic installations or small residential buildings to supply water at constant pressure. This group is equipped with a NASTEC MIDA frequency converter with the aim of maintaining constant pressure. This system, in addition to reducing energy consumption, increases the durability of the electric pump, as its mechanics are not always subjected to maximum speed and do not produces water hammer effects since the starts and stops are progressive. It is an Inverter system known as a frequency inverter, it is a more technologically advanced device that maintains the programmed pressure (up to the pump limit) unchanged regardless of the flow consumed.
Power Voltage: single phase, 1~230V
Fluid: Clean waters and non-aggressive or viscous liquids, free of solid substances.
Maximum fluid temperature: 45 ºC
Maximum suction height: 7 m
