Discussion Overview

The discussion centers on the search for a small rotary or axial pump with specific dimensions (2cm x 1cm x 1cm) and a flow rate between 1 cc/min and 50 cc/min. Participants explore the availability of such pumps in the market and consider alternatives, while addressing the need for a pump that can be connected to a drive unit via a cable.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses a lack of background in engineering or fluid mechanics and seeks assistance in finding a suitable pump.
  • Another participant suggests considering peristaltic pumps, noting their use in medical applications and their mechanism of operation.
  • A different participant mentions that peristaltic pumps are too heavy for their specific application and indicates interest in finding an integrated pump solution.
  • One participant references a manufacturer, Lee, that produces small pumps and provides a link for further exploration.
  • Another participant recommends checking companies listed on ThomasNet for micro pumps.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of the desired pump, and multiple competing views regarding potential alternatives and solutions remain present.

Contextual Notes

Limitations include the lack of specific technical specifications for the desired pump and the varying definitions of what constitutes "small" in the context of pump size.

Who May Find This Useful

Individuals interested in fluid mechanics, engineering applications, or those seeking small-scale pumping solutions may find this discussion relevant.

I need help, I have no background in engineering or fluid mechanics. I desire to find out the availability of a rotary/axial pump which has a size of 2cm X1 cm X1cm which can pump luids from 1 cc/min to 50 cc/min. The pump should be connected to the drive unit by a cable, so that the drive unit and pump can be separated. Power source can be either battery based or mains or both. My question is, is such pump avaialble in the market or do I have to get it fabricated? Anyone who can help?

You could try looking into peristaltic pumps. They are used in hospitals to pump fluids into people. In it’s simplest form it is a flexible hose that is squeezed by a cam and it pumps fluid without touching the fluid.

Alternatively look into aquarium pumps
 
Thank you, I have looked at the peristaltic pumps, but they are way too heavy for my application. I have found a micro motor which is just under 2cm in size, but have no small rotary fan blades to drive it, I was more intereted in knwoing if someone has the intergrated pump.
 
Thank you, I will check, sincerely, PB
