Flex separation systems, S-separators 928–988 Cleaning systems for heavy fuel oils* Separator Change-over valve Water block Flex system components for S-separators 928–988. Oil block including water transducer * S-separators can also be used to clean lighter fuel oils and lubricating oils. S and P Flex separation systems Alfa Laval’s S and P Flex separation systems com ine the b high efficiency, low sludge output and low operating cost of Alfa Laval centrifugal separators with a flexible scope of supply. Extensive possibilities for the separation system layoutand assembly make it possible to suit any engine room and any oil separation application. Application S-separators S-separators are based on Alcap technology, which means they automatically adjust the oil/water interphase based on the water content in the clean oil outlet. This makes them particularly suitable for separating heavy fuel oils with varyingdensity, though they can be used to clean all of the following: In addition, S and P Flex separation systems feature the EPC 60 controller, which enables the intuitive navigation of menus, parameters and alarms. The EPC 60 controller also has a modular construction for easy I/O board addition and replacement. • eavy fuel oils with densities up to 1 010 kg/m3 and H viscositiesup to 700 cSt/50°C (higher viscosities available upon request) • Lubricating oils • Distillates • Lighter diesel oils The S and P Flex separation concept includes the complete S- and P-separator range. These can be combined in mixed ship sets, even within a single customer-specified module. S-separators are designed for automatic operation in periodically unmanned engine rooms at sea and in automated

Scope of supply The S and P Flex separation concept provides a wide range of alternatives for S-separators. Depending on the need, a S-separator can be supplied as a separator and ancillaries, as a customer-specified module, or as part of a comprehensive ackage including services and orderp specific documentation. S separators 928–988 According to the prevailing ISO 8217 fuel standard for marine heavy fuel oils, the maximum allowable content of catalytic fines in bunkered fuel is 60 ppm. However, engine builders require that these levels be reduced by the separators to a maximum of 10...

Regulating valve Operating principle A Flex separation system based on an S-separator 928–988 is operated automatically by the EPC 60 controller. Untreated oil, heated to the correct temperature, is fed continuously to the separator, which is driven by an electric motor via a friction clutch and belt. 11. Solenoid valve block, water 12....

CentriShoot Instead of a sliding bowl bottom, the CentriShoot discharge system features a fixed discharge slide that flexes at its edge. This increases discharge accuracy and does away with metal-to-metal wear. CentriLock Conventional lock rings are threaded and must be removed with a sledgehammer. Over time, the metal-to-metal wear between bowl and lock ring can lead to expensive bowl repair or replacement. Step one: The CentriShoot discharge slide is fixed at the centre. During separation, the slide covers the discharge ports. An Allen key is the only tool needed to work with CentriLock....

Operations Preventive maintenance procedures are handled quickly and simply with the help of a compression tool. The snap ring of the patented CentriLock bowllocking system is non-threaded and requires only an Allen key to remove. • Maintenance intervals: - Inspection Service every 4 000 h or 6 months - Overhaul Service every 12 000 h or 18 months • Service spares kits contain all necessary spare parts for each service and tips for maintenance in checkpoints: - Inspection Kit with O-rings and seals for separator bowl - Overhaul Kit with parts for drive system, belt, bearings and pads, also...
