air pressure powered water pump

air pressure powered water pump

air pressure powered water pump

(OP)
Does anyone know of any pumps that use air pressure
to pump groud water from a well. I already know about diaphram pumps.

Thanks,
Lonnie

RE: air pressure powered water pump

Are you talking about air lift pumps?

RE: air pressure powered water pump

(OP)
No not specifically. What I have done is to design a pump on paper that uses stright air pressure to pump water from a well that does not use air lift principles or diaphrams.
What I am wondering is whether I am just reinventing the wheel. Are there any pumps out there in anyone's knowledge that uses these principles?

Best regards,
Lonnie Reed

RE: air pressure powered water pump

Lonnie:

If you are using air, then don't you have electricity near by to fun the compressor?  The inefficiency of generating compressed air compared to 92+ percent effiency for electric motors would make air a poor choice when a submersible or line shaft pump could be used.

Just my thoughts...

RE: air pressure powered water pump

All rotating pumps can be driven by a hydraulic or pneumatic drive. As the previous post points out, this is energetically inefficient.It may however be desirable in applications where it is required to have no electrical components in the area.

RE: air pressure powered water pump

Dependent on the depth of the well you might try US Pump Co. they make an air actuated pump that lifts 34'.

RE: air pressure powered water pump

The Chicago Industrial Pump Co. has what they call the Pitbull pump (www.pitbullpump.com) made for solids and slurries. Completely air operated--works like air padding a tanker trailer or rail car. The only moving parts are two check valves. I put a 4" model in a lime sump. It moved the rocks and pieces with no problem. Max flow was about 80 gpm and only used about 25 cfm of air.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
