The SUNTEC E 1069 oil pump is specially designed for heavy oil applications: it is fitted with a special type shaft seal resisting high temperature and with a preheater location to render cold starting easier.



- Heavy oil.
- One or two-pipe system
- Pump associated with in-line solenoid valve to assure cut-off function



The body of the E 1069 unit includes a drilling to accept an electric preheater. This cavity has been designed 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.

The heating cartridge can be fitted either by right-hand side or by left-hand side. The preheater should be connected for a period of time prior to starting the pump. When the right temperature is reached, it 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.



The gear set draws oil from the tank through the built-in filter and transfers it to the valve that regulates the oil pressure to the nozzle line.

All oil that 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 suction port in the gear-set. In that case, the by-pass plug must be removed from the return port and the return port sealed by steel plug and washer.

During starting period when the gear-set speed is increasing, all the oil passes through a special flat on the piston, back to the return. Once the speed reaches a certain value and the flow can no longer pass through this flat, then the pressure increases rapidly overcoming the valve spring force and opens the valve.



During the starting period, air is purged through the nozzle line : the by-pass hole of the nozzle plug allows air to pass to the nozzle line without opening of the regulator valve.
For the first start up, bleeding can be accelerated by loosening the plug in the pressure gauge port.
