Gear Pump - AFP Series
AFP Series Fuel Pressurizing Internal Gear Pump is a high-precision positive displacement internal gear pump designed for fuel pressurizing, injection, lubrication, and oil transfer applications. It offers reliable performance, self-priming capability, high suction lift, and efficient handling of low to medium viscosity liquids.
Overview
Product Overview
The AFP Series Internal Gear Pump by Sando Rotary Equipments is engineered for demanding industrial fuel and lubrication applications. Manufactured from graded cast iron construction with precision internal gears, the pump ensures long service life, smooth operation, and accurate flow delivery.
The pump is flange-mounted and equipped with an inbuilt pressure relief valve along with an external bypass arrangement for enhanced operational safety and pressure control. Mechanical seal arrangement minimizes leakage at high pressure conditions, making it suitable for continuous-duty industrial environments.
AFP Series pumps are self-priming and capable of generating high vacuum suction, providing superior suction lift compared to conventional external gear pumps. The pump can handle liquids up to 500 cSt viscosity and temperatures up to 200°C. Rotation direction can be configured clockwise or anti-clockwise as required.
These pumps are ideal for clear and non-corrosive liquids such as LDO, FO, and LSHS, and are widely used in boiler systems, burners, lubrication systems, diesel locomotive booster systems, filtration systems, and machine tools.
For selection, evaluate flow rate, discharge pressure or head, viscosity, temperature, solids content, material compatibility, and installation conditions. Sando Rotary supports industrial buyers with application-led recommendations for gear procurement.

Selection Guide
Positive Displacement vs. Centrifugal Pumps
Selection Point 1
Positive displacement pumps suit controlled flow, higher viscosity, and pressure-sensitive transfer.
Selection Point 2
Centrifugal pumps suit continuous movement of clean, low-viscosity liquids at stable duty points.
Selection Point 3
Final selection should be based on duty point, fluid behavior, installation conditions, and maintenance goals.
