Designed from the wellknowed TA pump range, the SUNTEC TAR oil pump is specially designed for industrial heating applications using Marine Residual Fuels (as defined in ISO 8217 standard). TAR pump offer superior resistance to wear and improved pump life for abrasive fuels applications.
The gear set draws oil from the tank and transfers it to the valve regulating the oil 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.
The plug of the pressure gauge port must be loosened until the air is evacuated from the system.
All TAR models are delivered for two-pipe system (by-pass plug fitted in vacuum gauge port).
For one-pipe system, the by-pass plug must be removed and the return port sealed by steel plug and washer.
Care should be taken to avoid starting pump with high viscosity cold oil leading to pump and coupling damage. For this reason, the TAR 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.
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.
