2GP 2CDX DOMESTIC PRESSURE BOOSTING TYPICAL APPLICATIONS The base of the group is in galvanised steel as are the manifolds. The discharge manifold is set-up to gather two vertical membrane reservoirs. Mounted on them find two pressure switches, the electric control panel and a pressure gauge. On suction, each electric pump has an isolating valve and a non-return valve, with the possibility of connection to an air supply unit and has another isolating valve in discharge mode. Protection and control panel with CE mark • IMQ and VDE marked components • Very low voltage auxiliary circuit • Motor switch-on and switch-off are controlled by two pressure switches • The connection to a float of minimum pressure pressure switch is possible in order to prevent functioning in conditions when there is no suction water • A device is present that inverts the insertion order of the pumps at every start-up • Power supply: - 230V, 50Hz single phase - 400V, 50 Hz three phase • Direct start-up • Power circuit protection fuses • Auxiliary circuit protection fuses • Protection rating IP 55 • Line main isolating device with door lock • Aut - 0 - man. switches for each pump • Reset circuit breaker protection • Indicator LED: - network presence - motor running - level alarm - motor in protection mode (for three phase version only) • Alarm output set-up • On request, special version control panels can be used Units with two horizontal dual impeller pumps with stainless steel hydraulic parts. PUMP FEATURES FIELD OF USE • Maximum working pressure: 8 bar • Maximum temperature of the liquid: 60°C MATERIALS • Pump body, impeller, shaft, nozzle and seal housing disc in AISI 304 • Motor support in aluminium (up to 1.5 kW included), in cast iron (2.2 kW and over). TECHNICAL DATA • Self-ventilated 2 pole asynchronous motor • Class of insulation F • Protection rating IP55 • 230V ± 10% 50Hz, single phase voltage 230/400V ±10% 50Hz three phase voltage • Permanent capacitor inserted and thermo-amperometric protection with automatic reset incorporated for the single phase motor Data under revision.

FUNCTIONING PRINCIPLES The withdrawal or however the escape of water from the system with the pumps at a standstill, causes the pressure to drop and the consequent closure of the pressure switch contact with highest calibration, which determines start-up of the first electric pump. If the outlet discharge exceeds the flow rate of a pump, the pressure continues to drop until it causes the closure of the contact of the second pressure switch and the start-up of the second pump. The end of the distribution of the reduction of the outlet discharge leads to the pressure in the system rising, with opening of the pressure switch contacts and staggered pumps stops. The inversion of the ignition order of the two motors reduces the number of hourly start-ups of the individual pumps and consequently allows a homogenous use of the same. By connecting a float or minimum pressure pressure switch to the control panel (whether for withdrawal from the primary collection reservoir or from the hydraulic circuit), the most frequent cause of electric pump breakdown is prevented: the lack of water at suction.
