Pumps: Head, Discharge & Lubrication Oil Recommendations

Click For Summary

Discussion Overview

The discussion revolves around the characteristics of pumps, specifically focusing on head, discharge, and recommendations for lubrication oils. Participants seek to understand the physical meaning of head and the relationship between head and discharge in various applications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant defines "head" as static pressure but notes that the best type of pump depends on the specific application.
  • Another participant suggests that reciprocating pumps generally have high head and low discharge, while centrifugal pumps typically have low head and high discharge.
  • A participant provides a website link, presumably for further information on pumps.
  • Another post appears to be an incomplete or unclear response regarding pump success.

Areas of Agreement / Disagreement

There is no clear consensus on which pump is best for specific applications, and multiple viewpoints regarding pump characteristics are presented.

Contextual Notes

The discussion lacks detailed definitions and may depend on specific applications or conditions that are not fully articulated.

Hi all,
I want to know the details of the pumps such as

  • [*]Which of the pump has the highest head?
    [*]Which one has the Highest Discharge?
    [*]The one highly recommended for lubrication oils?



  • [*]What is the real physical meaning of head?
    [*]The relation between Head and Discharge in physical terms...


Thank You.,., Expecting your Reply

"Head" is static pressure. For the rest of that, we need to know the application to know what type of pump is best for it.
 
generally, for similarly sized units, reciprocating pumps have high head & low discharge & centrifugal pumps have low head & high discharge.
