Self-priming
Pump is self-priming up to 3m (for F4B 4 m). Intake lines must be air-tight to ensure selfpriming.
Note: Pump will prime when impeller is dry but suction lift up to 3m (for F4B 4 m) is only obtainable
when impeller is lubricated with liquid being pumped or Johnson Impeller lubricant.
For permanent installations where suction lift exceeds 4 m, a foot valve should be used to assure priming
on start up.
Continuous duty
For continuous duty 0,6 bar (60 kPa) maximum head is permissible. Normal working temperature of the
motor may reach approx. +80°C (surface temperature) which may burn your skin.
Varning! Dry running
Do not run dry for more than 30 seconds. Lack of liquid will burn the impeller and damage the seals.
If the pump is used for fuel oil transfer it should be equipped with a vacuum switch. When the liquid has
been evacuated the electric supply is automatically switched off.
Varning! Caution Explosion Hazard
Do not pump gasoline, solvents, thinners, highly concentrated or organic acids. If corrosive fluids must
be handled, pump life will be pro-longed if flushed with water after each use or after each work day.
Varning! Caution. Explosion Hazard.
Never operate a motor which in any way has been manipulated and lost it's full enclosure.
Temperature
Max ambient temperature: +60°C. The life of the impeller depends on the temperature of liquid being
pumped.
Temperatures between +5°C and +55°C give normal life. Higher or lower temperature will reduce the
life.
When the pump is used as bilge pump
Max total head 6 m. The pump must be installed so that the motor is protected from splash from bilge
water.
The pump must be fitted with a strainer or other means of preventing debris from entering the pump.
Freezing weather
Drain unit by loosening the endcover. Glycol based anti-freezes can be used but do not use petroleum
based anti-freeze compounds.
