Frequently Asked Questions

What is the Suntec AP two-step pump used for?

The Suntec AP two-step pump is a fuel oil pump with a built-in solenoid that provides two-mode pressure operation. It is used in industrial and commercial burners for domestic oil, kerosene, HVO, and B30. It supports one-pipe or two-pipe systems and requires a separate cut-off valve.

What are the specifications of the Suntec AP pump?

The Suntec AP is a two-step model with a gear-set capacity shown in pump capacity curves. It is compatible with domestic oil, kerosene, HVO, and B30. Solenoid coil voltages include 220-240 V AC (50/60 Hz) or 110-120 V AC (50/60 Hz). Shaft rotation and nozzle location options are A, B, C, or D.

Where to buy the Suntec AP pump in Singapore?

You can source the Suntec AP pump through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on availability. 3G Electric provides technical support for selection and integration into your burner system.

How to install the Suntec AP two-step pump?

For installation, set the high pressure with the solenoid activated before adjusting low pressure with the solenoid non-activated. For two-pipe systems, keep the by-pass plug in the return port. For one-pipe systems, remove the by-pass plug and plug the return port. Bleeding is done via the nozzle plug by-pass hole.
