VFD SILENT VARIO Variable speed Pressure Groups

Description

Automatic pumping sets for the supply at Constant Pressure and Variable Flow.

Equipment with frequency converter. Made up of one or more pumps to maintain the pressure constant, the system regulates the r.p.m. or frequency of the pumps, in function of the required flow.

Advantages:

• Reduction of the accumulation tank.
• Pressure is maintained constant.
• Elimination of jolting in the pipes.
• Reduction of the number of maneuvers, thus lengthening the useful life of the pumps.
• Energy saving up to 80%.
• Sequence variation of the pumps input. (ALTERNATION)

Due to its the special design, the set can work as a classical booster set by pressure switches, which are already included.

Composition:

• Pumps mounted on a common baseplate.
• Discharge collector.
• Pressure transducer.
• Electric panel, metallic box with forced ventilation system, with magneto thermal protection.
• General switch.
• Stop-Start switches per pump, fuses, connection leads.
• Electronic frequency converter for manual or automatic operation, which can be programmed by PLC.
• Electronic display showing the working functions.
• Pressure switches, pressure gauge, spherical valve, one per pump (valve to isolate pressure gauge and pressure switches).
• Max. Room temperature 45ªC.
• Connections scheme.
• Membrane accumulator.

For other performances, please consult.

Various pump models can be used, those indicated are only an example of the most common ones.
