Description

Set for the supply or the increase of the pressure for clean waters.

It consists of ONE or several identical pumps mounted on a baseplate and with a common impulse collector

Monophasic equipment and three-phase equipment.

CONSTANT PRESSURE GROUP and variable speed with a single pump. GP-1-SP

It works with a technologically advanced system that maintains the unchanged programmed pressure by varying the engine speed according to water demand.

Very Important energy saved and large durability of the engine.

Group with TWO Pumps GP2-SP. It works as above, but also if the demand is high than the flow of a pump, the second one enters into operation to maintain the same pressure, set alternate and work in cascade.

FUNCTIONING:

It is programmed in the DISPLAY, the working pressure that we want in the installation. When the working pressure decreases due to the water consumption, the pump starts, automatically maintaining the constant pressure and increasing the speed if the water demand increases.

The group automatically stops when consumption ceases.

In the case of the missing of water for feeding the set group automatically the SPEEDBOARD detects it and stops the group avoiding damaging the pump.

COMPOSITION

Simple group GP-1-SP Pressure group with ONE pump

Frequency inverter connected and installed in the motor terminal box

Frequency variator connected and installed in the motor terminal box

Closing valve

Retention valve

Pressure transducer installed in the pump

Accumulator

Double group GP-2-SP Pressure group with 2 pumps

Mounted on a baseplate with common impulse collector

Connection panel with cut-off switch

Check valves 2

Closing  valves 2

Frequency variation equipment installed in terminal boxes of motors-2

Accumulator

MOST IMPORTANT ADVANTAGES:

Alternative and cascading operation

Lack of water protection.

Overcurrent protection.

Variation of speed and constant pressure predetermined.

External pressure transducer with fault auto-detection

Equipment incorporated in the motor terminal box

Frequency inverter for the management of the electric pump

Function ART, when the equipment is disconnected by the intervention of the protection system due to lack of water, the ART with scheduled periodicity, connects the equipment until the restoration of the water supply.

Automatic system of rearmament after accidental interruption of power supply. The equipment is activated keeping all the parameters of configuration.

Contact potential-free switching to monitor alarms caused by system irregularities indicated on the screen (optional)

Conexioines for detection of minimum water level in suction tank. This system is independent of security due to lack of water.

STC function, when the temperature of the electronic board exceeds 85ºC it automatically decreases the frequency of rotation of the electric pump decreasing the generation of heat but maintaining the water supply.

Control panel with screen.

External pressure transducer from 0 to 10 bar or 0-16 bar according to need

Intensity sensor with digital instant reading

On-screen operational control record: working hours, start counter, electrical connections counter

Alarm record. Information on the screen of the number and type of alarms generated since its start-up

Important energy saving.
