    Unique positive displacement pump questions

    Hello, I have a few unique questions for pump designers for a racing application. I design racing shocks, I've never designed a pump and will begin looking for a technical partnership after I hopefully get a few questions answered. The micro "pump" will be inside a damper and won't actually...

    Back driving a rotary pump

    It is in oil Flow reverses often and suddenly 1-2" bore tubing so pretty small, low flow velocities. Completely custom design is expected. I need the oil to force the pump/turbine shaft to rotate CW/CCW as flow moves forward/reverse through it with good response on changes in direction. I 3D...

    Back driving a rotary pump

    Two with check valves may be possible but trying to avoid due to doubling cost, weight, and space.

    Back driving a rotary pump

    There is one part to this I guess I left out that is quite important. Flow reverses often and suddenly so a turbine and many pump designs wouldn't work which is why I was looking at a helix. Perhaps some form of a gear pump or rotary pump is the only way this will work in both directions.

    Back driving a rotary pump

    Hello, I'm not sure if its the right term for this but can a rotary or centrifugal pump be driven by a pressure differential across the pump gears? I'm looking to create rotary shaft motion with fluid flow through a cavity. My first thoughts on this were to force flow through a solid piston...
