The best pumps for street cleaning machines

Street sweeping machines represent one of the most demanding applications for high-pressure pumps: they require high flow rates, pressures kept constant over time, and a design engineered to withstand the vibrations of moving vehicles. In this in-depth article, we analyze the technical specifications that a pump for street sweeping machines must have, the flow rate and pressure parameters that are actually needed in street and municipal washing operations, and the different power options available (hydraulic motor or combustion engine). In the second part, we present the dedicated Hawk range, with a focus on the XXT and TXT series, designed respectively for the most compact vehicles and for high-capacity street sweeping trucks.

Pumps for street sweeping machines: essential technical specifications

Street sweeping machines operate under tough conditions: their job is to clean large road surfaces, sidewalks, tunnels, plazas, and urban areas. To do all this quickly and with reasonable water consumption, the pump must combine a medium-to-high flow rate, typically between 70 and 150 liters per minute, with an operating pressure in the 120–200 bar range.

Added to these requirements are equally important technical features:

• Reliability in continuous operation, because the shifts of street sweeping machines are often extended and take place during time windows in which machine downtime is particularly costly.
• Compatibility with the vehicle's power source, through direct coupling with hydraulic or internal combustion engines, since the pumps work installed on board the vehicle and do not depend on a fixed electrical grid.

What are the best pumps for street sweeping machines?

The best pumps for street sweeping machines are piston pumps capable of operating continuously with medium-to-high flow rates in the 70–150 l/min range and pressures in the 120–200 bar range. Hawk has developed a specific range for the municipal sector, presented on the application page municipal cleaning, where high-pressure pumps are used for cleaning roadways on street vehicles such as street washers and sweepers.

Within the range, depending on the size of the machine and the flow rate required, the most suitable series are the XXT for compact vehicles, the MXT and the MXT High Flow for intermediate configurations, and the TXT for large-sized street sweeping trucks. For vehicles in which the pump is powered directly by the vehicle's hydraulic system, Hawk also offers the "-HY" versions of these series, already designed for coupling with hydraulic motors.

Hawk piston pumps for street sweeping machines: the dedicated range

The XXT series for compact street sweeping machines

The XXT series is designed for smaller machines, where the primary requirement is combining a significant flow rate with a compact footprint. With flow rates ranging from 41 to 70 l/min and a maximum pressure of 210 bar, the XXT is particularly suited for cleaning urban streets, sidewalks, bike lanes, and pedestrian areas. The XXT-HY version, with a flow rate of 55 to 70 l/min, is the variant dedicated to hydraulically powered vehicles, which can be coupled to hydraulic motors using the appropriate flange and flexible coupling systems.

The TXT series for street sweeping trucks

The TXT series, on the other hand, is designed for the most demanding configurations: street sweeping trucks, heavy-duty urban sanitation vehicles, and specialized vehicles for cleaning tunnels and high-speed roadways. With a flow rate ranging from 120 to 220 l/min and a maximum pressure of 250 bar, the TXT makes it possible to treat large surfaces in a short time while maintaining stable performance even during extended shifts. In street cleaning applications, the pump generally operates in the 150–200 bar pressure range, fully leveraging the high flow rate available.

Hydraulic power: how to configure the pump

Since these are moving vehicles, piston pumps for street sweeping machines are normally powered by a hydraulic motor. The "-HY" versions of the Hawk range are optimized for coupling with gear or piston hydraulic motors, with rotation speeds and torque compatible with the control units typically found on this type of vehicle. The pumps for hydraulic motors section brings together all the series designed for this type of installation.

Why choose Hawk for street cleaning pumps

Hawk pumps for street cleaning are designed, manufactured, and tested at the LEUCO S.p.A. plants in Reggio Emilia, in a production cycle certified ISO 9001:2015, ISO 14001:2015, ISO 50001:2018, and ISO 45001:2018. The range was developed starting from the real needs of the municipal sector, where operating life, reduced maintenance, and the availability of dedicated coupling accessories directly affect the total cost of vehicle management throughout its life cycle. To identify the most suitable pump for your street sweeping machine, taking into account flow rate, pressure, power type, and dimensions, Hawk's technical support is available to advise on the right configuration.
