SUNTEC AL35B Light Duty Heating Oil Pump Z-27:
$40

OIL PUMP TYPE AL
GEAR SIZES 20-35-55-65-75-95

This is a general specification leaflet; for specific applications not covered herein, contact Suntec.

The SUNTECALoil pump incorporates a blocking solenoid valve with in-line cut-off function.

APPLICATIONS

- Light oil, B10 heating oil/biofuel blend (as defined in DIN V51603-6) and kerosene.- One or two-pipe system.

PUMP OPERATING PRINCIPLE

The gear set draws oil from the tank through the built-in filter and transfers it tothe nozzle line via the cut-off solenoid valve. A pressure regulating valve is used to dump all oil which is not required at the nozzle.
In two-pipe operation, the by-pass plug must be fitted in the return port, whichensures that the oil dumped by the regulating valve is returned to the tank andthe suction line flow is equal to the gear set capacity.

In one-pipe operation, the oil which does not go through the nozzle line is returned directly to the gear inlet and the suction line flow is equal to the nozzle flow. In that case, the by-pass plug must be removed from the return port, andthe return port sealed by steel plug and washer.

Bleed

Bleeding in two-pipe operation is automatic (except for AL 20) : it is assured by a bleed flat on the piston.
For AL 20 in two pipe operation, and for all models in one-pipe configurationthe plug of a pressure gauge port must be loosened until the air is evacuated from the system.

Cut-off

The solenoid valve of the AL pump is of the "normally closed" type and is situated in the nozzle line. This design ensures extremely fast response and the switching can be selected according to the burner operating sequence and is independent of motor speed.

When the solenoid is non-activated, the valve is closed and all oil pressurized by the gear set passes through the regulator to the suction or return line, depending upon pipe arrangement.
As soon as the solenoid is activated, oil passes to the nozzle line at the pressure set by the pressure regulating valve.
