IPG20 MK3Protection intelligente de pompe

Conçu pour les systèmes d’irrigation en eau claire comme en effluents. Apprend la pression de fonctionnement à chaque démarrage du système, puis applique ses propres seuils de sous- et surpression pour une détection très ciblée des fuites et surpressions. Convient aux îlots fixes ou aux rampes mobiles.

Dimensions

Dimensions IPG20 MK3
Three views with key dimensions (mm). 1" BSPT thread connection; paddle is cut to suit application; three M20 cable glands; removable protective cap.

Self-Learning Pressure Algorithm

The IPG20 MK3 measures the system’s normal operating pressure each time it starts and uses that as the reference for under- and over-pressure detection. As the irrigator travels over varying terrain the auto-terrain-compensation function adjusts the reference downward / upward in real time, so leak and blockage thresholds remain meaningful even as system pressure changes naturally.

Flow Sensitivity & Paddle Trimming

The IPG20 ships with one paddle (suits pipes 25 mm and larger) and two trailing wires (suits 65–100 mm ID, subject to velocity). The flow at which the paddle activates depends on pipe size, viscosity, and trimmed paddle length. Use the online Paddle Calculator to estimate activation flow and determine how much to trim the paddle for your application.

3-Phase Pump Motors

The IPG20 MK3 can be used to control either single-phase or 3-phase pumps, provided a 220–240 V AC or 24 V AC/DC supply is available at the installation site. For 3-phase motors the IPG20 drives an interposing contactor — use the Pump Controller Power Calculator to size the contactor and verify cable rating + voltage drop.

Application Restriction

The IPG20 MK3 is an industrial control device, specifically designed for use in dairy and agricultural applications. It must never be used for any other application. Installation must be carried out by a qualified pump engineer, and all electrical work by a licensed electrician.

Hazardous Areas

The IPG20 MK3 is not certified for use in hazardous areas and must not be installed in any area classified as hazardous under AS/NZS 60079.10 (Zone 0, 1, 2, 20, 21 or 22).

Maintenance

La protection intelligente de pompe IPG20 MK3 n’est pas entretenable par l’utilisateur. Toutefois, des pièces de rechange sont disponibles auprès de Kelco Engineering ou de votre distributeur.
