Maxaflow Use

The Maxaflow pump works very simply - to set it up and start pumping, simply follow the instructions below.

1. The drum must be in an upright position with the drum plugs at the top. Remove the 2”  plug (note: keep the ¾” plug fitted in the vent outlet of the drum), then fasten the Maxaflow valve insert by screwing it into the 2”  fitting of your drum.
2. Fit the dip tube into the red outlet port and push it down to the bottom of the drum.  Then plug the bellows foot pump into the blue inlet port.  The pump is now ready to work.
3. To start, prime the pump with a couple of depressions of the bellows pump. Open the valve/dispensing nozzle and fluid will start flowing. To maximise flow and minimise effort we recommend five pump depressions followed by a two second interval then cycle again. This will give a flow rate of approximately 60 litres per minute. 
4. Once flow is required to stop, close the valve or dispensing nozzle and flow will stop.
5. If the pump is no longer required the excess air pressure in the drum should be vented. Care should be taken in doing this to avoid any fumes or liquid spilling out and contaminating yourself or the area around you.
6. First remove the pump from the blue inlet port and insert a blunt instrument to the blue port and unseat the valve to release the pressure. At this point any hose line liquid that is not required can be drained back to the drum by positioning the line so there is uninterrupted fall back to the drum insert and opening the delivery valve.
7. The bellows foot pump should then be cycled three or four times to remove any collected fumes from inside the bellows, then remove the dip tube from the red outlet port and unscrew the Maxaflow valve insert and reinstall the 2” plug into the drum.

Having trouble getting your Maxaflow to flow?  If so, below are the most common issues for you to check;

• Check contents level of the drum and that the dip tube is fully inserted.

• Check for air leaks that will prevent the liquid from being displaced.

• Excessive lift height. If the deliver point is vertically separated from the drum top by more than the standard hose length, the drum will need to be repositioned closer to the discharge point. 

• Check the bellows pump, for punctures in the fabric or damaged valve/s. The pump should produce 4 psi of pressure, (this pressure can push a head 2.5 metres above the surface of water).

• Check for crimping of the outlet hose. The standard hose (springflex) cannot crimp unless crushed (run over). A non standard soft wall hose may easily collapse and prevent the system from working efficiently.
