The Mixer Shafts & Washers Series for Putzmeister® concrete pumps includes the essential components that power the mixing mechanism inside the hopper. These high-strength rotating shafts, paired with durable washers and mounting hardware, are engineered to support and drive the mixing paddles that continuously agitate concrete—preventing aggregate segregation and maintaining workability.
Precision-engineered to OEM specifications, these components ensure optimal performance, reliability, and extended service life in the demanding conditions of concrete handling and pumping.
Key Features & Benefits:
Consistent Mixing Performance: Designed to promote thorough and continuous agitation, ensuring homogenous concrete for smooth pumping and placement.
Heavy-Duty Construction: Crafted from high-tensile steel to resist wear, deformation, and torsional stress during operation.
Exact Fit & Alignment: Manufactured to match Putzmeister® original dimensions for easy installation and superior performance in any compatible hopper setup.
Corrosion & Abrasion Resistance: Treated with protective finishes to resist damage from moisture, cementitious materials, and harsh environmental conditions.
Variety of Models & Configurations: Available in multiple shaft lengths, diameters, and paddle-mounting designs to suit a wide range of Putzmeister® mixer assemblies.
Secure Paddle Attachment: Includes rugged washers and fasteners that ensure paddles remain firmly affixed to the shaft, even under continuous load and vibration.
Full OEM Compatibility: Engineered for seamless integration with Putzmeister® hopper assemblies and hydraulic or electric mixer drive systems.
Component Overview (Based on Image):
Mixer Shafts (Silver Cylindrical Units with Mounts): Central rotating components to which paddles are bolted. Feature flanged bases for secure mounting to the hopper structure.
Colored Shaft Variants (Yellow & Red): Likely represent mixer shaft variants for different pump models or custom paddle configurations. May differ in size, connection type, or load capacity.
Washer Sets (Metal Discs): Used to lock paddles onto the shaft and prevent axial movement. May be separate hardware or integrated into the shaft design as flanges or shoulders.
Operational Role in Putzmeister® Pumps:
The mixer shafts and washers play a vital role in the pre-pumping phase by ensuring the concrete mix remains uniform and pumpable:
Mixing: The shafts support paddles that churn the concrete within the hopper to prevent material separation.
Rotation Transfer: Power from the mixer motor is transferred through the shaft to the paddles, ensuring consistent motion and energy distribution.
Paddle Stability: Washers and securing mechanisms keep paddles tightly attached to the shaft, even under high torque and continuous movement.
Why It Matters:
A well-functioning mixer shaft system is critical to the success of concrete delivery:
