Suntec D57C Heavy-Oil Pump – Part No. 73723P
The Suntec D57C 73723P is an industrial burner pump for light, medium and heavy-oil applications.
Viewed from the shaft end, the C configuration provides anticlockwise rotation with a left-hand nozzle outlet. It has H32 mounting, G1/4 inlet and return connections, a G1/8 short nozzle outlet and an additional pressure port on top. Its operating pressure range is 10–28 bar, with a 14-bar delivery setting.
The pump supports one-pipe or two-pipe installations, oil viscosity up to 75 cSt and pump temperatures up to 90°C.
The Suntec D57C does not provide integral cut-off. An external in-line solenoid valve is required where burner cut-off is needed. Do not replace a D57A with a D57C without confirming shaft rotation and nozzle position.
