Q: How Deep Should I Submerse My Pump?



A: As deep as possible. The deeper, the better, as the greater the head of water above the pump, the quicker it will re-fill for the next pumping cycle.
Therefore a higher delivery rate. The limit is primarily the capacity of the compressor to lift the water. The highest pressure is required at start-up (up to 1psi (6.9kpa) per meter (3ft) of total lift.

Q: My Pump Is Not Pumping! What Should I Do?


A:  - Check the air supply and condition of hoses and joints. The compressor must be able to deliver enough pressure to lift the water (up to 1 psi per meter or 3ft of lift)

- Check the condition of the water delivery piping

- Wiggle the Pump up and down in case of lodgement of solid particles in the valve seats, preventing proper sealing

- If you have a timer/controller, check it's settings and operation

- If all of the above are in order, contact our technical team through your supplier

Q: When Do I Need A Timer/controller To Regulate The Cycle Time?

A: The pump works in 2 stages:

a: The water (fluid) charging stage
b: The air intake and liquid discharge stage.

In shallow submersion situations, where water depth (pump submersion) is less than 1/3 of total lift height, the static pressure at the pump inlet is not enough to keep filling the pump.
The Timer/controller periodically shuts off the air to the pump and at the same time vents the pump, allowing water to enter and fill the pump chamber. Then the air is put back onto the pump, pushing the parcel of water up the delivery line.

When there is good water depth (over 1/3 of total lift height), no Timer/controller is required, as there is enough static water pressure at the pump inlet to keep filling the pump.

Q: How Do I Keep My Pump From Pumping My Bore/Well Dry?


A: Turn down the air flow to reduce the pump rate. If that is still too fast, you can install a timer on the compressor to limit the period of operation to match the delivery of your bore/well.
If you have a Timer/controller, extend the intervals to slow down the flow.
