Afriso

The SP32 01-D is a single-stage suction pump, while the SP32 02-80E-D is a two-stage electric-drive pump. The single-stage model is typically used for lower-pressure applications, such as small commercial burners with shorter fuel lines. The two-stage model provides higher pressure differentials, making it suitable for larger industrial burners or installations with longer pipe runs and higher elevation changes. The 'E' in the model designation indicates an electric motor drive, whereas the 'D' refers to the pump's design series. Both pumps are built to the same SP32 platform, sharing flange dimensions and shaft couplings, which simplifies interchangeability in retrofit scenarios.

The SK9E/FP8E-F pressure unit is primarily designed for light fuel oil (diesel) applications. For heavy fuel oil, Afriso offers alternative configurations with appropriate seals and heating elements, but the standard SK9E/FP8E-F is not recommended for heavy oil due to viscosity and temperature requirements. Always verify the specific model's compatibility with your fuel type by consulting the technical datasheet. If you require heavy fuel oil capability, contact 3G Electric for guidance on selecting the correct Afriso pressure unit variant.

The SP32 series covers flow rates typical of gravity-feed and pressure-head applications, generally ranging from approximately 10 to 40 liters per hour, depending on the model and operating pressure. The exact flow rate is influenced by the pump's stage count, motor speed, and the viscosity of the fuel oil. For precise specifications, refer to the pump's performance curve, which is included in the original documentation supplied with each unit. This range makes the SP32 suitable for burners rated from small commercial (around 20 kW) to large industrial (up to several hundred kW) capacity.

Afriso components are designed to meet European standards and are built for integration into standardized burner-control configurations. The SP32 pumps feature standardized flange dimensions and shaft couplings, which often allow direct replacement of legacy units from other manufacturers, such as Danfoss or Suntec, in many installations. However, always verify the mounting dimensions, shaft type, and pressure ratings against your existing equipment before ordering. The SK9E/FP8E-F pressure unit is designed for panel mounting with standard port sizes, but cross-compatibility should be confirmed on a case-by-case basis.

Routine maintenance for Afriso SP32 pumps includes periodic inspection of the shaft seal for leaks, checking the inlet filter for debris, and verifying that the pump's pressure settings remain within the specified range. The pump's bearings are typically sealed and require no lubrication, but the coupling alignment should be checked annually. If the pump is used with heavy fuel oil, more frequent cleaning of the internal components may be necessary. Always follow the maintenance schedule in the installation and operating manual supplied with the pump. Spare parts, such as seals and filters, are available through 3G Electric.

Yes, 3G Electric offers technical support to help you select the appropriate Afriso pump or pressure unit for your application. Our team can assist with interpreting model designations, reviewing performance specifications, and confirming compatibility with your burner system. We can also provide documentation such as datasheets and installation guides to aid in your decision. For complex retrofits or new installations, we recommend consulting with a qualified combustion engineer, but our support team is available to answer questions about product specifications and availability.
