ESPA DPR Automatic Water Pump up to 7.2 m3/h

Horizontal multistage centrifugal pump , silent and with excellent performance, suitable for domestic applications, pressure groups and irrigation systems.

Equipped with an electronic device for automatic control and protection of the electric pump, this system is equipped with an electronic sensor integrated into the circuit that controls the starting and stopping of the electric pump and has a safety system against dry running.

It replaces the traditional autoclave, pressure switch, check valve and level switch system. This device automatically switches on the electric pump when any water point is opened and stops after a time delay of 15 to 20 seconds as soon as there is no more water consumption.

Very compact, quiet and with great suction power!

Group composition

• #1 - ESPA electric pump model PRISMA .
• #2 - DPR pump controller.
• #3 - 1" Male Thread PVC Joint.

It is a compact device for automatic control and protection of electric pumps up to 2,2 kW (3 HP) , multi-voltage (110-230 V) and equipped with an innovative outlet pressure reduction/regulation system . It also includes a digital display with instantaneous indication of current consumption and outlet pressure since it is equipped with current and pressure transducers inside.

In addition to the typical features of traditional electronic pump controllers

• Integrated non-return valve;
• Accumulation diaphragm;
• Pressure gauge;
• Dry-running protection;
• Automatic reset;

It allows you to adjust and stabilize the output pressure, avoiding overloads in the hydraulic network, water hammer and, ultimately, improving the comfort of the end user.

Features

• Power relay for managing electric pumps with powers up to 2,2 kW (3 CV) ;
• Power supply from 110 to 230 Vac .
• Manual regulation of outlet pressure, with built-in regulation tool.
• View of the output pressure adjustment.
• Digital adjustment of the starting pressure.
• Digital pressure gauge in bar and psi .
• Integrated pressure sensor.
• Integrated flow sensor.
• Integrated current consumption sensor (A) .
• ART (automatic restart) function. This system will perform a series of automatic starts to try to restore operation without the need for manual intervention using the RESET button .
• APR function (anti-blocking periodic routine) . After 3 days of inactivity, the device triggers a 10 -second restart to prevent the motor rotor from blocking.
• Configurable against flooding. With this function enabled, the pump will stop after a programmed time of continuous operation.
• stand-by mode.
• Control and protection system for electric pumps against overcurrents, dry running due to lack of water, overpressure, flooding and rotor blockage.
• The control panel includes - 3 -digit display , flow indicator, bar/psi indicator, alarm indicator.
• Recording of operational data and alarms.
• Built-in accumulation membrane and non-return valve.
• Connections to the water network - 1” .
