Motori servizio continuo S1

I motori elettrici offrono elevate prestazioni stabilizzando la temperatura di esercizio in valori costanti per un utilizzo illimitato grazie al servizio continuo in S1.

La potenza del motore scelta per l’accoppiamento alle pompe è sempre sovradimensionata in modo che la potenza richiesta dalle pompe non raggiunga mai i valori massimi disponibili. 

Pompe professionali 1450 rpm

Le pompe in linea a 3 pistoni in ceramica sono ampiamente sovradimensionate, permettendo l’utilizzo solo parziale della pressione massima per cui sono state progettate.

Questa caratteristica, unitamente a quella dei motori elettrici in servizio continuo S1, permette alle idropulitrici Indra di lavorare senza pause di raffreddamento.

L’accoppiamento pompa-motore non è diretto, bensì è realizzato mediante giunto elastico per permettere che nel tempo, in caso di rottura del sistema di accoppiamento, l’intervento sia di lieve entità e rapido e non con la prospettiva di grosse operazioni di sostituzione di componenti. 

Sistemi di sicurezza avanzati

Le idropulitrici Indra sono dotate di una solida scheda elettronica, specificamente progettata, che gestisce le funzioni della macchina e tutte le segnalazioni. 

Tutte le funzioni e segnalazioni vengono gestiti in completa sicurezza, garantendo la risoluzione immediata di eventuali guasti. La gamma è infatti dotata di sicurezze avanzate e la scheda elettronica segnala al riparatore, con appositi led posti sul circuito stampato, il corretto funzionamento o eventuali avarie dei componenti elettrici. Vi è inoltre una segnalazione completa delle funzioni direttamente sul pannello comandi per consultazione e controllo da parte dell’utilizzatore.

The only mobile high-pressure cleaner with a 20l rotoformed water tank

Indra is designed with a large-capacity water tank which, thanks to its vertical shape, allows a perfect supply to the pump, which always receives water under pressure and without air bubbles. This structure gives great manoeuvrability and great usability and allows to occupy a reduced space on the ground.

The electronic board is highly professional.

The autotransformer that distributes the power supply is independent of the circuit board and fixed on a metal plate.

On the printed circuit board, a number of micro-led lights alert maintenance staff to the origin of any malfunctions.

Heavy-duty electric motors, which stabilise the operating temperature at constant and absolutely suitable values, and largely over-dimensioned 3 ceramic piston inline pumps, which work by only partially utilising the maximum operating pressure for which they have been designed 

allow each model to be used continuously without the need for cooling pauses.

For coupling to 21 L/min 150bar pumps, an 8.5HP motor is correctly chosen and not 7.5HP as is commonly used.

The pump-motor connection is by means of a flexible coupling located in the gap between the two motor flanges.

Sturdy, impact-resistant and compact: • Structure made of a tubular frame and a thick platform, mounted on 2 fixed and 2 pivoting wheels for great manoeuvrability • Thick stainless steel front and top covers, removable for efficient and immediate routine maintenance • 3 ceramic piston pump • 1450 rpm electric motor, continuous duty S1 • Pump-motor connection with double flange and elastic coupling • Pressure control valve  • Safety valve • Very robust, large-capacity integrated rotomoulded tanks • Anti-limescale product dosing pump, controlled by the PCB • Water filter • Fuel filtering system with 3 filters.

the tanks

The 20 L water tank has been designed to have an extremely large capacity and difference in height between the water inlet and the suction. This allows the pump to be constantly fed under pressure, prevents air bubbles from being sucked in and compensates for any lack of inlet pressure.

The 24 L fuel tank has a large capacity and an internal level sensor that is sealed by contact with a gasket and not by expansion of a rubber ring. It also has a drain tap at the bottom.

The 12 L detergent tank can be removed (in 1 minute) for maintenance, giving easy access to internal components, or emptied and washed, allowing easy change of detergent.

The 9 L anti-limescale tank is equipped with a level sensor and a dosing micro-pump. A warning light on the control panel signals when the pump stops due to lack of anti-limescale liquid. The micro-pump will start up again after refilling.

INDRA Professional high pressure washers


Indra is protected by a multiple security system: With regard to combustion, safety in the Indra range is guaranteed by a microswitch (5), a pressure switch (1) and a flow switch (4). The burner start and stop functions are regulated by sensing both water flow and pressure.

If one of the devices fails, signalling lack of flow or pressure, combustion is in any case immediately stopped or burner ignition is not permitted.

This multiple system gives an extra guarantee that combustion will stop even if the water no longer circulates in the coil, avoiding the risk of overheating.

care for every detail

In addition to the considerable technical advantages described, its characteristic structure is extremely ergonomic. The handles at the back, unlike conventional high-pressure cleaners, are positioned at the correct height and make it easy to move the cleaner.

The lance has a dedicated housing: a stainless steel support and a pressure hook anchor the lance firmly to the back of the structure, making it easy and safe to move the cleaner.

The diesel filler cap at the rear is in an easy position. There is also a convenient holder for winding the power cable. In the version without a hose reel, there is space for a high pressure hose holder.

INDRA riempimento gasolio


Diesel filtration system consisting of:

A.  Pre-filter, for the retention of coarse particles (120 µm)

B.  Cartridge filter to retain the finer impurities (31 µm)

C.  Self-cleaning filter immersed in diesel to prevent suction of processing residues. A counterweight keeps it constantly on the bottom.

The adoption of this triple filtration system does not allow the operation of the diesel pump to be altered, keeping the small emergency filter with which it is equipped clean at all times.

robust and impact-resistant

The load-bearing structure consists of a tubular frame and a very thick platform (18 kg). To complete the bodywork, two covers, one at the front and one at the top, are made of thick stainless steel. 


When designing Indra, great consideration was given to immediate access to each of its components.

Simply remove the detergent tank by loosening three screws, and remove the front and top covers for easy access to all serviceable components.
