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.
PUMP INSTALLATION

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)
