Alfa Laval MOPX 207, a self-cleaning disc-stack centrifuge

"MOPX 207," which is most likely the Alfa Laval MOPX 207, a self-cleaning disc-stack centrifuge used for separating liquids and solids, commonly in industrial applications like oil purification. Since your input is brief, I’ll assume you want general information about it. If you meant something else, please clarify! The Alfa Laval MOPX 207 is designed for continuous three-phase separation—typically separating oil, water, and sludge—in industries such as marine, power generation, biodiesel production, and food processing. It’s compact, with a stainless steel bowl and an aluminum body, and operates at a maximum bowl speed of around 6,400 RPM. Its hydraulic capacity can reach up to 7,400 liters per hour (about 32 gallons per minute for lighter fluids like distillates), though this varies with the viscosity of the material being processed. The centrifuge uses centrifugal force to remove impurities, automatically discharging sludge at intervals, which makes it efficient for handling large volumes of oil or fuel. Common uses include purifying marine diesel oil, lubricating oil, or waste vegetable oil (WVO). It’s powered by a 7.5 kW (10 HP) motor and is valued for reducing oil loss by up to 50% in some setups, cutting operational costs. The system is fully automated except for startup, and it can function as either a purifier (removing water and sludge) or a clarifier (focusing on solids), depending on the configuration. The Alfa Laval MOPX 207 is a self-cleaning, disc-stack centrifuge designed for three-phase separation, commonly used to purify oils (e.g., marine diesel, lube oil, or waste vegetable oil) by separating water, sludge, and oil. Below are its key technical specifications, compiled from available industry data: • Model Variants: Typically listed as MOPX 207 SGT-24-60 (specific configurations may vary slightly, e.g., SGT or TGT designations). • Maximum Bowl Speed: 6,321–6,400 RPM (varies slightly depending on motor setup and reconditioning). • Hydraulic Capacity: Up to 7,400 liters per hour (LPH), or approximately 32 gallons per minute (GPM) for distillates. Capacity depends on oil viscosity (e.g., 15–26 GPM for heavier oils). • Motor Power: 7.5 kW (10 HP), though some units are fitted with a 5.5 kW (7.5 HP) motor depending on application. • Motor Voltage: Typically 230/460V, 3-phase, 60 Hz (configurable to 380/440V in some reconditioned units). • Bowl Material: Stainless steel (e.g., T-316 for contact surfaces). • Frame Material: Aluminum body with cast iron or steel framing. • Sludge Capacity: Maximum of 8 liters before automatic discharge. • Operating Modes: Can function as a purifier (separates water and sludge from oil) or clarifier (focuses on solids removal). Water is discharged continuously in purifier mode, sludge intermittently in both modes. • Process Temperature: Minimum 0°C, maximum 100°C (32°F–212°F). • Maximum Feed Density: 1,100 kg/m³ (oil); sediment density up to 2,362 kg/m³. • Dimensions: Compact design, typically around 1,200 mm (H) x 800 mm (W) x 1,000 mm (L), though exact size varies with skid or pump inclusion. • Weight: Approximately 500–600 kg (1,100–1,320 lbs), depending on configuration (e.g., with or without feed pump). • Drive System: Direct drive with a variable frequency drive (VFD) in some setups; worm gear and shaft system rated for 1,420–1,500 RPM at the motor end. • Additional Features: o Self-cleaning bowl with automatic intermittent sludge discharge. o Fully automated operation (manual startup required). o Optional EPC-41 control unit for temperature and process control (not standard in all units). o Includes gravity disc set, tools, and vibration dampers in most reconditioned packages. These specs make the MOPX 207 versatile for industrial uses like marine oil purification, biodiesel processing, and power plant lube oil treatment
