PH Series Steam Washer Industrial Quality 400V Mazzoni 210bar 15l/min

Performance Characteristics

The PH model series from the Italian manufacturer Mazzoni describes the series of high-performance hot water high-pressure cleaners with 400V designed for industrial, highest demands and continuous operation.


The PH4000TST series has a large 5.5 kW electric motor that drives an autonomous high-pressure crankshaft pump unit with a flexible coupling at 1,400 rpm. The motor pump unit provides a working pressure of 210 bar at a flow rate of 15 l / min. Compared to the simple axial high-pressure pump, this is characterized, for example, by its particularly smooth running. The organs of the high-pressure cleaner such as the stainless steel burner housing, the crankshaft high-pressure pump unit with full ceramic pistons are designed for continuous industrial operation and are correspondingly robust and durable components. The external blue pressure / volume regulator (circulation valve) ensures, for example, quick and uncomplicated maintenance and enables the working pressure and flow rate to be regulated.


The high-pressure cleaner is a hot water device, which means that it can produce hot water on its own because it has a diesel burner. This enables the water to be heated to around 80 ° C (ΔT) at the maximum flow rate, which significantly improves the cleaning performance. If the flow rate is reduced on the blue pressure regulator, the diesel burner can continuously heat the water up to 150 ° C.
The operating display provides information about the operating status and shows fill levels and any system error messages. The device is equipped with all safety sensors such as optical flame monitoring, low water protection and an external fan motor. The PH4000 has an internal detergent tank, the suction of which can be regulated and which further increases the cleaning effect. The machine also has an internal automatic descaling system, the liquid addition of which is accessible from the outside.


The associated double-jet lance is equipped with the industrial quick-release system and enables stepless pressure regulation with constant flow rate.
The design and characteristics of this high-pressure cleaner correspond to the very highest industrial quality standard in terms of motor-pump unit, burner technology, etc.


Please keep in mind that when used with power generators, they must generate at least 2.5 times the power of the electric motor for smooth operation due to the high starting current.


The Mazzoni company existed in northern Italy in 1969 as a manufacturer of high-pressure cleaners, steam jets and individual components such as burners, high-pressure crankshaft pumps and attachments. The owner-managed family company with around 80 employees continues to produce everything by hand and only supplies top-quality components and devices in a rock-solid design for continuous industrial operation. The focus here is on quality, not profitability. The supply of spare parts and / or maintenance is guaranteed by our workshop in 65205 Wiesbaden, other dealers and German-speaking contacts at Mazzoni.
