The unit is driven by two 400V, 15kW, 50Hz, EX nA electrical motors each connected to a screw pump with an approximate circ flow of 200 l/min at 35bar, and a 3kW electrical motor connected to a vane pump with a circ flow of 7 l/min at 150 bar, which generates pulsation effect at app 400 l/min. The unit is able to operate with pipe dimensions from 1” to 4” depending on fluid viscosity and temperature, ensuring a pipe system cleanliness level better than ISO 4406 16/14/11 or Nas 1638 Class 5. The pulsation is generated through a 10 l accumulator which is pressurised through the 7 l/min, 150 bar vane pump. The high pressure from the accumulator is then automatically periodically released to the low pressure flushing circulation, which generates a very high turbulent pulsed flow. The pulsations are particularly an advantage in systems with high differential pressure. In order to ensure precise and stable working pressure the unit is provided with a PRV (pressure regulation valve) The starter panel is fitted with on/off push buttons, on/off light indications, emergency stop and 10 meter connecting cable with a 63 A electrical plug.
