Product Overview

The Suntec ALE Oil Pump is a one-stage gear pump designed for oil burner systems that require precise fuel pressure control and reliable shut-off performance. The pump integrates a blocking solenoid valve combined with a return valve, enabling an in-line cut-off function and providing automatic nozzle line pressure relief.

Inside the pump, a gear set draws oil from the tank through a built-in filter and transfers it to the burner nozzle through the solenoid valve. A pressure regulating valve maintains the correct fuel pressure, while excess oil is returned to the tank in two-pipe installations or recirculated internally in single-pipe systems.

The integrated return valve ensures that the ALE pump maintains the same dimensions and performance characteristics as the AL pump, while adding a pressure relief function for improved safety.

The pump supports various fuels such as light oil, kerosene, HVO biofuel, and biofuel blends, making it suitable for modern industrial heating systems and burners.

Technical Description

The Suntec ALE Oil Pump operates with a precision gear mechanism driven by the burner motor. The rotating gears draw oil from the fuel tank through an internal filter and deliver it toward the nozzle line through the solenoid valve.

When the solenoid valve is energized, oil flows to the nozzle at the pressure set by the regulating valve. When the valve is not energized, the oil is diverted back to the suction or return line depending on the piping configuration.

The integrated return valve ensures nozzle line pressure relief, preventing pressure buildup caused by thermal expansion of fuel in the system. This improves burner safety and protects fuel components.
