This diesel transfer pump is designed to reliably transfer
diesel. The pump is a self priming, positive displacement,
rotary vane pump operating on either 12 or 24V DC
depending on the model. The pump will deliver up to 40
litres per minute, has a built-in bypass valve that keeps the
operating pressure below 1.3 Bar (18 psi) and the motor
has a 30 minute duty cycle
If you require a fuel filter or meter for your pump, Macnaught
recommends that you use the Macnaught HA1S fuel filter
and/or select one of the Macnaught fuel meters.

to ensure a good connection.
3. Always relieve the line pressure by opening the nozzle,
draining hose. Disconnect power before starting any
pump maintenance
4. Hoses should be inspected regularly.
(Replace if found to be cracked or worn)
5. The rotor and vanes will eventually wear. They should
be replaced if pump performance degrades.
(refer to trouble shooting guide)
NOTE: Tanks or barrels should be anchored to prevent
tipping in both the full and empty conditions.
