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.
PUMP OPERATING PRINCIPLE
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 by-passed 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.
