Pressurization systems for electric pumps

Description

• Pressurisation system composed of 1, 2 or 3 electric pumps, assembled in a unit ready to be installed.
• The system is available in mechanical version with fixed speed or in inverter version with variable speed.
• Suction manifold with ball valves and delivery manifold with non-return valves.
• One pressure switch for each electric pump for the fixed speed systems; a pressure transducer for each electric pump for the variable speed systems.
• The switchboard has a thermomagnetic switch, a power relay and an automatic exchanger to control the alternating working of the pumps

• 2 poles asynchronous motor, 50 Hz, 2850 rpm.
• Class F insulation.
• IP44 protection.
• Working voltage: single-phase 230 V, three-phase 400V.
• External ventilation.

• Pumped liquid: clean water, non-aggressive, without so lid particles.
• The pumps cannot operate in dry conditions.
• Temperature of pumped liquid: min 5 °C – max 30 °C.
• Water feed pressure: min 0,2 – max 3 bar.
• It is essential to connect the system at least to no. 1 minimum 24 l pressure tank for each pump.
• Maximum number of starts per hour: 20.
