Sermac Pumping Cylinders & Piston Ram

Pumping cylinders and piston ram assemblies form the heart of Sermac concrete pumping systems. These critical components operate in tandem to move concrete through the pump, delivering consistent pressure and flow during demanding construction tasks. The piston ram connects the concrete piston to the hydraulic drive, ensuring efficient transfer of force during both the suction and delivery strokes.

Key Features:

• Heavy-Duty Construction: Engineered from high-tensile steel or wear-resistant alloys to endure the extreme pressures and abrasive nature of concrete pumping.

• Precision Fit & Finish: Machined to tight tolerances for optimal piston movement and minimal energy loss.

• Advanced Sealing Systems: Integrated with high-performance seals and rings to prevent leaks of both hydraulic fluid and concrete slurry.

• Modular Assembly: Designed with clearly defined mounting flanges and connection points to simplify integration and maintenance.

• Anti-Corrosive Treatment: Select components may include coatings or finishes (e.g., nitriding or powder coating) to enhance resistance to corrosion and wear.

Primary Functions Within Sermac Pumps:

• Suction Stroke: The cylinder and piston draw concrete from the hopper into the pumping chamber.

• Pressure Stroke: The piston ram pushes the concrete from the cylinder into the delivery line.

• Power Transmission: The piston ram transfers hydraulic force from the actuator to the concrete piston.

• Seal Integrity: Maintains seal alignment and performance during high-pressure operation.

Component Identification (Based on Visual Cues):

• Black Angled Flanged Component: Likely a cylinder end housing or flange adapter that connects the pumping cylinder to the hopper or other structural elements. The angled section may assist in redirecting concrete flow.

• Black Cylindrical Component (with internal detailing): Possibly a piston core or internal ram head, designed to hold seal assemblies and transfer mechanical force.

• Blue Cylindrical Component: Likely a piston head featuring wear-resistant coatings. The central opening and flanged design suggest compatibility with ram rods or hydraulic connectors.

• Silver Hollow Tube: A piston ram or connecting sleeve that transmits hydraulic force to the concrete piston. May feature internal threads or grooves for assembly alignment.

Identification & Ordering Notes:

To ensure proper fit and function, provide the following when sourcing parts:

• Sermac pump model and serial number

• Part number or stamped markings (if available)

• Installation location within the pump assembly

• Dimensions: Including cylinder bore, piston diameter, stroke length, flange diameter, or thread specs

• Photographic reference (optional): A photo of the part in situ or removed can aid suppliers

Important Considerations:

Using OEM or certified-compatible pumping cylinder and piston ram components ensures:

• Maximum pumping efficiency

• Reduced downtime due to failures

• Optimal compatibility with existing Sermac systems

• Extended service life for high-wear components
