This is a general specification leaflet ; for specific applications not
covered herein, contact Suntec. PUMP
IDENTIFICATION
The SUNTEC T oil pump is specially designed for industrial heating applications
using light or heavy oils with high capacity. It is fitted with a preheater location to (Not all model combinations are available
Consult your Suntec representative)
render cold starting easier.
APPLICATIONS
- Light and heavy oil (for kerosene applications, contact SUNTEC). T : No pressure regulation
- SUNTEC recommend the use of a SUNTEC TV valve to regulate the pump
pressure.
Gear set capacity
PUMP OPERATING PRINCIPLE (see pump capacity curves)
The gear set draws oil from the tank and transfers it to an external valve that
regulates the oil pressure.
Shaft rotation
Bleed : (seen from shaft end)
The plug of the pressure gauge port must be loosened until the air is evacuated from A : clockwise rotation
C : anti clockwise rotation
the system.
Note :
The bypass plug inserted beween high pressure and shaft seal is only intended to
change the pump rotation, check the presence of this plug with a 4 mm Allen key

in the pressure outlet of the pump.
Caution : changing the direction of pump rotation involves changing of all pump
connections.
PREHEATING FACILITY
Care should be taken to avoid starting pump with high viscosity cold oil leading to
pump and coupling damage. For this reason, the T pump body includes a drilling Preheater facility
to accept an electric preheater. This drilling has been located to give maximum heat
transfer from the heater to the oil in the pump without there being 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.
