Putzmeister Boom Pump Outer Housing Steel Material Spare Part OUTER HOUSING OEM Reference: 240391003

1Extreme wear resistance This is the most critical feature of the upper casing. Due to its direct contact with high-speed flowing concrete, the inner surface is usually made of a high-chromium wear-resistant alloy or undergoes a special heat treatment process. This material is highly resistant to the brushing of sandstone and cement sludge, and its service life is multiplied compared to ordinary cast iron parts, significantly reducing downtime costs due to frequent replacement of accessories.

2. Precision machining, eliminate leakage Putzmaster's original housing is highly precise in machining. It has a fine circular structure inside and a flat outer flange. This high-precision combination ensures a perfect seal between the glass plate, the cutting ring and the S-tube, effectively preventing the leakage of high-pressure concrete sludge (i.e. "running sludge") and ensuring construction safety and efficiency.

3. Original factory interchangeability, trouble-free installation As a factory replacement for "Elephant" (such as the common part number 274893001 or 401783, etc.), its dimensional tolerances strictly follow the original factory standards. This means that when installed, the bolt hole position and pipe interface can be seamlessly docked with the original car without any modification, greatly reducing the maintenance time, ensuring that the equipment can be quickly resumed.
