Water depth is and remains over 1/3 of the total vertical lift. The deeper you can submerse the pump in water, the more it will deliver. Water level self-regulates by virtue of the pump's design and operating principle.
Delivery rate can be as much as 8000L/hr, depending on the water source, submersion in water, lift above the water, air supply and piping size.
Vertical lift up to 100m (300ft) is no problem with a regular 5 to 15cfm off-the-shelf compressor. If the lift is higher, please contact us to discuss.
Submersion in water should be no more than around 65m (190ft) if using a regular 130psi compressor.
Bore casings need to be at least 4 inch ID (100mm)
