herein, contact Suntec.
PUMP
The SUNTEC TA oil pump is specially designed for industrial heating applications IDENTIFICATION
using fuel oil #2 to #6. It is fitted with a preheater location to render cold starting (Not all model combinations are available
easier. Consult your Suntec representative)

APPLICATIONS

- Fuel oil #2 to #6 (for lighter oil and kerosene applications, contact SUNTEC), TA : Pressure regulation
B6-B20 (blends from 6% up to 20% biodiesel, per ASTM D396).
- One or two-pipe system.

PUMP OPERATING PRINCIPLE

Gear set capacity
The gear set draws oil from the tank and transfers it to the valve regulating the oil (see pump capacity curves)
pressure to the nozzle line. All oil which does not go through the nozzle line will
be dumped through the valve back to the return line in two pipe installation or, if it
is a one-pipe installation, back to the gear-set.
Shaft rotation
Bleed :
(seen from shaft end)
The plug of the pressure gauge port must be loosened until the air is evacuated A : clockwise rotation
from the system. C : anti clockwise rotation

Note :
All TA models are delivered for two-pipe system (by-pass plug fitted in vacuum
gauge port).
TA 2 A 40 10 7
For one-pipe system, the by-pass plug must be removed and the return port sealed
by steel plug and washer.

PREHEATING FACILITY
Model number
Care should be taken to avoid starting pump with high viscosity cold oil leading to
pump and coupling damage. For this reason, the TA pump body includes a cavity
to accept an electric preheater. This cavity has been located to give maximum heat
transfer from the heater to the oil in the pump without direct contact between the
heater cartridge and the oil. Revision number
Heaters should be connected for a period of time prior to starting the pump. When
the right temperature is reached, they can be switched off or left permanently
switched on to maintain fluid oil in the pump during the periodic burner shut-downs.
The oil supply, pipes and filters must be separately heated.
