The Industrial Legacy of Sharples Centrifuges

The Sharples brand has defined industrial separation for over a century. Founded by Philip M. Sharples, the company pioneered high-speed centrifugal technology that remains a cornerstone of modern manufacturing. A Sharples decanter centrifuge is a horizontal solid-bowl machine designed for continuous liquid-solid separation. Unlike batch processing, these units handle high-volume feed streams without interruption, making them the industry standard for heavy processing environments.

The Super-D-Canter series is particularly well-regarded in the sector. These machines use extreme G-forces to pull solids against the bowl wall while an internal screw conveyor moves them toward discharge. It’s a simple, robust mechanical principle. The primary benefit of this design is the sheer efficiency of the separation. By applying thousands of Gs, the centrifuge achieves a level of cake dryness that traditional filters simply can’t match. This reduces downstream drying costs and improves overall process yields. Because these units are typically constructed from high-grade stainless steel, they resist corrosion and abrasive wear for decades. This is why finding a used Sharples centrifuge for sale is often preferred by engineers who value proven mechanical reliability over modern digital complexity.

The Alfa Laval Connection and Parts Sourcing

Sharples was eventually acquired by Alfa Laval. This is a critical detail for anyone maintaining older equipment. The acquisition ensured that technical specifications and parts support remained available globally. Today, a used Sharples centrifuge for sale in the Australian market is a viable long-term investment because parts are still supported. Reconditioned parts are also widely available locally, ensuring that a machine from a previous generation can still meet modern production uptimes without the risk of obsolescence.

Why Buy Used Sharples Equipment in 2026?

The economic case for used machinery is pragmatic. New European-made separators often come with significant price tags and lead times that can stretch for many months. Sourcing used equipment through an Australian supplier reduces these lead times to weeks. There are also clear environmental benefits to this approach. Repurposing a multi-ton stainless steel machine prevents the carbon-intensive process of smelting and manufacturing new frames. For an Australian plant, it’s a choice that balances capital preservation with immediate operational readiness.

Technical Breakdown of Sharples Model Series

Selecting a Sharples decanter requires an understanding of how different model series handle specific process variables. The Sharples catalog is generally divided into the P-series and the PM-series, each engineered for distinct industrial scales. The P-series, which includes well-known models like the P600, P3000, and P3400, is the versatile workhorse of the range. These units are frequently utilized in food processing, chemical manufacturing, and light industrial dewatering. They’re valued for their balance of footprint and throughput, making them a common sight in Australian processing plants.

For higher capacity requirements, the PM-series is the preferred choice. Models such as the PM35000 or PM70000 are built for high-volume industrial applications, including municipal wastewater sludge and large-scale mineral processing. These machines feature larger bowl volumes and higher torque gearboxes to manage the increased solids load. Technical efficiency in both series is largely a function of the bowl’s length-to-diameter (L/D) ratio. A higher L/D ratio increases the residence time of the slurry, which is essential for capturing fine particles that are difficult to settle. When you’re evaluating a used Sharples centrifuge for sale, it’s vital to check the G-force rating. Higher G-forces, often exceeding 3,000 Gs, result in drier cake discharge and clearer centrate, though they also place more stress on the mechanical components.

The Super-D-Canter Design Advantages

The Super-D-Canter design utilizes a conical-cylindrical bowl to achieve optimal separation. The cylindrical section is where the liquid clarification occurs, while the conical section, often called the “beach,” acts as a ramp for solids dewatering. An internal screw conveyor, or scroll, rotates at a slightly different speed than the bowl to push the settled solids toward the discharge ports. In abrasive environments, such as those involving sand or grit, it’s critical to source units with hard-surfaced conveyors. These are typically protected by tungsten carbide tiles or specialized weld overlays to prevent the scroll flights from eroding prematurely. This design ensures that the machine maintains its solids-handling efficiency over long production cycles.

Matching Model to Material: Flow and Solids

Matching the machine’s RPM and horsepower (HP) to your material’s viscosity is a fundamental step in the sourcing process. Low solids concentrations require high bowl speeds to generate the force needed for effective clarification. Conversely, high solids applications demand high-torque gearboxes to manage the physical resistance on the conveyor. Many modernised units now feature Variable Frequency Drives (VFD). These drives allow operators to fine-tune the differential speed between the bowl and the scroll, providing the flexibility needed to handle varying feed consistencies. You should also ensure any unit you consider meets OSHA safety standards regarding interlocks and rotating parts. If you’re unsure which specific model fits your current flow rates, you can view our current inventory to compare technical specifications across our available stock.

Technical Inspection: Verifying a Used Centrifuge

Evaluating a high-speed decanter requires a rigorous technical checklist. The centrifuge bowl rotates at several thousand RPM, generating significant kinetic energy that demands perfect balance. Any imbalance isn’t just a maintenance concern; it’s a structural risk to the entire plant. When you’re inspecting a used Sharples centrifuge for sale, the gearbox is often the most critical component to verify. Whether it’s a Sun and Planet or a Cycloidal design, the gearbox requires a clear lubrication history. You should look for signs of oil leakage at the seals or metallic shavings in the lubricant, as these indicate internal gear wear. Additionally, examine the product contact areas. While Sharples units utilize high-grade stainless steel, chemical erosion can still occur over decades of service. Finally, verify the integrity of the main drive and back drive motors by checking winding resistance and bearing condition to ensure the electrical system matches the mechanical state.

Bowl and Conveyor Wear Patterns

Erosion typically appears first on the conveyor flights and the solids discharge ports. These areas bear the brunt of the abrasive slurry as it’s forced out of the machine. Bowl pitting or corrosion must not exceed manufacturer-specified depth tolerances, as surface irregularities can compromise structural integrity and sanitation. Securing a used Sharples centrifuge for sale is only a sound investment if these tolerances are strictly met. You should also inspect the feed pipe for thinning or internal blockages. A thinned feed pipe can eventually fail, leading to process contamination or expensive internal damage to the conveyor hub.

Operational Testing and Maintenance Logs

Documentation is as important as the physical hardware. You should request the maintenance history, focusing specifically on bearing replacements and seal integrity. A well-documented machine suggests a disciplined operational environment where the equipment wasn’t pushed beyond its design limits. If possible, conduct an operational test run before finalising the purchase. Listen for high-pitched whining or rhythmic knocking, which often signals bearing failure or gearbox misalignment. Vibration monitoring equipment should be used during this test to ensure the unit operates within the “good” zone of standard industrial vibration charts. Finally, check that the control panel is functional and that all safety interlocks are responsive. A machine with bypassed safety sensors is an operational liability that you don’t want in your facility.

Industry Applications and Process Integration

The application of a Sharples centrifuge varies significantly depending on the material’s physical properties and the desired process outcome. In wastewater treatment, these units are primarily used for sludge dewatering, where the goal is to reduce sludge volume for cost-effective disposal. Food and beverage processors utilize sanitary-grade stainless steel units for clarification tasks, such as removing fine solids from fruit juices or edible oils. For chemical processing involving volatile solvents, vapor-tight designs are essential to contain hazardous fumes and maintain plant safety. In the mining sector, high-durability decanters manage tailings, often requiring the hard-surfaced conveyors discussed in previous sections to handle abrasive mineral slurries effectively.

Integrating with Stainless Steel Tanks and Pumps

When sourcing a used Sharples centrifuge for sale, it’s important to consider how the machine will interface with your existing infrastructure. A centrifuge is only as effective as the system surrounding it. Sizing the feed pump is critical; it must provide a consistent flow rate without shearing the flocculated solids. Typically, positive displacement pumps are used to feed the slurry into the machine. used stainless steel tanks for sale play a vital role here, serving as buffer storage to ensure a steady feed concentration. Proper tankage allows for pre-treatment, such as polymer dosing, which is necessary for efficient liquid-solid separation. You must also plan for the discharge of the clarified liquid and the dewatered solids. This often involves a combination of screw conveyors for the cake and dedicated piping systems for the centrate.

Machinery Relocation and Installation in Australia

Moving a multi-tonne centrifuge across state lines presents specific logistical challenges. These machines are precision instruments despite their massive industrial scale. Any rough handling during transport can damage the internal bearings or misalign the bowl assembly. Utilizing professional industrial machinery relocation services ensures the unit is decommissioned, transported, and positioned correctly. Once on-site, the centrifuge base must be perfectly leveled and anchored to a vibration-dampening foundation. Even a slight misalignment can lead to excessive operational vibration, which shortens the lifespan of the gearbox and main drive.
