PUMI 25-4

Truck Mixer Concrete Pump with 4-Arm Placing Boom

The original PUMI® by Putzmeister combines pump, mixer and placing boom in a single machine. It is an addition to the fleet of truck-mixers held by service and customeroriented suppliers of ready-mixed concrete and significantly extends the range of jobs they can take on: a PUMI® is particularly economic wherever truck-mounted concrete pumps are too expensive or too big and inflexible or wherever truck-mixer conveyor belts are not adequate. In particular, it can be operated cheaply and quickly in small construction sites up to approximately 20 m³.
