APPLICATIONS
Vertical multistage centrifugal pump suitable for medium to large user water systems. Recommended for pressurisation units, boiler supply, hot water and cooling water circulation, fire fighting and washing systems, drinking water supply and filling of pressure vessels, sprinkler and watering systems and water purification systems.
ADVANTAGES OF USE
Operating pressure stability - Excellent energy savings (up to 60 % ) - Reduced hammering effects - Reduced space requirements - Less maintenance - Reduced pump wear - Less power factor correction required - Less water consumption - Integrated protections.
CONSTRUCTION FEATURES OF THE PUMP
Cast iron delivery and suction bodies treated against corrosion. Impellers, diffuser bodies and diffusers in technopolymer. AISI 304 stainless steel pump liner and adjustment rings. Pump shaft in AISI 416 stainless steel. AISI 316 stainless steel sliding bushing.
Bronze sliding bushing guide, self-lubricated using the pumped liquid itself. Carbon/ceramic mechanical seal. Rigid coupling motor shaft to pump shaft connection. Threaded counter-flanges supplied as standard.
CONSTRUCTION FEATURES OF THE MOTOR
Shaft with rotor running on permanently lubricated ball bearings, oversized to ensure low noise and durability. Construction according to CEI 2-3.
Controlled by MCE inverter. Insulation class: F. Standard single-phase voltage: 1x230 V / 50-60 Hz. Special version on request: three-phase 3x400 V / 50 Hz or three-phase 3x460 V / 60 Hz. Standard three-phase voltage: 3x400 V / 50 Hz. Special version on request: 3x460 V / 60 Hz.

MCE/P INVERTER
CONSTRUCTION FEATURES OF THE ELECTRONICS: MCE/P INVERTER
The inverter continuously adjusts the rotation speed of the electric pump, keeping the pressure constant, even when the flow rate varies.
The other electric pumps, also with variable speed, are activated in cascade after the first one has reached maximum speed. Through modulation, they compensate the pressure fluctuations of the system.
For every operating cycle, it is possible to switch the restart to a different pump, therefore ensuring even use of all electric pumps.
It is possible to set operation times for each individual pump, switching to another pump after such set times.
The "SP" pressure can be adjusted by the user using the "+" and "-" keys found on the MCE/P (as a rule, all the pumps are set to the same pressure value). With the new MCE/P, it is sufficient to set the data on one of the devices, and it will be automatically propagated to the other pumps of the system.
