PRESFLO - ELECTRONIC PRESSURE AND FLOW MONITOR FOR GARDEN AND WELL - DICOUNT ONLY WITH WELL SET

Product no.: 225-001

Electronic pressure and flow monitor for garden and well pumps - at a special price only in conjunction with our well construction packages. A 1.5 m connection cable with Schuko plug plus 0.5 m cable coupling is supplied for this purpose. The connection cable with plug is already mounted.


The Presflo® New is a device for automatically switching electrically operated garden and well pumps on and off. It protects the pump against running dry and starting up too frequently.


Mode of operation:

The Presflo® switches the pump on when the system pressure drops below the operating pressure Pm when a tap is opened (see product images). The control unit ensures smooth pump operation even at low flow rates and switches the pump off when the requested flow rate is very low or drops below the shut-off flow rate Qa.


Advantages:

    Compact unit with small dimensions, no separate expansion tank required.
    Sturdy housing made of technopolymer, suitable for drinking water distribution systems.
    Horizontal or vertical installation possible.
    Protection of the pump against dry running.
    Protection of the pump against too frequent start-up.
    Protection against overpressure by special diaphragm.
    Special valve guarantees constant pump operation even at low volume flows of 1 - 2 L/min.
    Extremely low pressure loss: allows operation with pumps with volume flows of up to 200 L/min.
    Insensitive to moisture (IP65 protection class housing, control board cast in synthetic resin).
    Maintenance-free.


Fields of application:

    Domestic water supply
    Private service water supply
    Garden irrigation


Notes:

During installation, it is essential to ensure that the pressure generated above the Presflo® by the water column does not exceed the operating pressure Pm. Otherwise the Presflo® would not switch on the pump.

The Presflo® can be used with clean and chemically non-aggressive water. The unit must not be operated in explosive environments. The ambient temperature should be between 0°C and 65°C. Do not install the Presflo® in permanently damp rooms or environments. The humidity must not exceed 90%. Please observe the instructions in the operating manual.
