The Suntec A2VA-7116-B is a single-stage oil pump designed for efficient fuel delivery.  Operating at 3450 RPM, this flange-mounted pump is factory-set to 100 psi, with a flow rate of 3 GPH at 100-150 psi and 2 GPH at 150-200 psi.  It features a right-hand rotation with a right-hand nozzle port location.  UL-listed and CSA-certified, it meets industry safety and performance standards.
 
It incorporates a unique circuit that provides a dependable cut-off, a high single-pipe lift capacity, and automatic two-pipe purging.  This ensures consistent operation and ease of maintenance.  Additionally, it is specially designed for B20 biodiesel applications, featuring Viton O-rings, a lip seal, and specialized materials for the piston and diaphragm valve, making it compatible with fuel oil #2 and biodiesel blends from 6% to 20% (B6-B20) per ASTM D396 standards.

The A2VA-7116-B is a direct replacement for models A2VA-7116, JJ2BA-300, JJ2BA-100, JJ2BB-100, and JJ2BB-300.  Ideal for residential and light commercial heating applications, the pump supports one-pipe systems with the flexibility for two-pipe configurations if needed.  However, it is not compatible with fuel blends containing more than 20% biodiesel.
