BSF 20
Unmatched Versatility in a Compact Design
Whether you are just starting out, or adding more flexibility to your existing fleet — Putzmeister’s BSF 20-4 is a cost-effective option. The compact design allows easy maneuvering through busy, urban job sites. The versatile four-section Z-Fold boom, with 19.46 meters of vertical reach can operate in challenging places including areas with low ceilings.
This is possible because both the Multi-Z and Z-Fold configurations can begin a pour before the boom is fully unfolded. A standard swivel elbow, off the back-end with a 90-degree pivot, also allows you to use the BSF 20-4 as a City Pump. Another integral component is the Ergonic Output Control (EOC) which reduces fuel consumption, wear and noise. An easy-to-use graphic display lets you keep track of hydraulic fluid temperature, operating hours, delivery pressure and limit, and delivery rate and limit.
