Hello! Welcome to the wonderful world of pumps. Learn about pumps
and pump systems. You can do calculations and trouble-shoot pump problems, everything is FREE.
Need a shoulder to cry on, check out the forum. Whhhooo... and there's lots more:
This web site has no affiliation with any pump manufacturer.
These apps allow you to make calculations directly on a web page (no java applets) or on your mobile browser. You can calculate: velocity, head from pressure, pipe friction, N.P.S.H.A, submergence requirement, specific speed, suction specific speed, pipe dimensions and pipe stress.
The following videos are a re-constitution of a presentation I gave in September 2014 to the Society of Piping Engineers and Designers of Calgary. It's a basic introduction to pump systems.

This video is a blackboard style of presentation that shows how friction is calculated with formulas.
Calculating friction with formulas
This spreadsheet allows you to do your own calculations.

CENTRIFUGAL PUMP TIPS
If you're currently designing a system or checking out an existing one, here are some ideas on what to avoid and what to look for.
An alphabetical list of pump and pump system terms that will show as well as explain the terminology.
This section is devoted to NEW ITEMS that have been added to the site or just interesting downloads or ideas that I have come across. Updated on April 9, 2009
I am back from Australia where I was working on a pulp & paper project near Melbourne.
Australia....what a place. I will miss it.
Yeah I know these are crazy pictures but it's my life. OK, down to business,
