You can also try the actual pump manufacturers, i.e. www.grundfos.com, www.ksb.com, etc.  This then implies that you should either know the specific model you want or what the parameters are so you can do a web pump selection.  Most pump manufacturers are quite helpful if you contact them.  Also under the "Supplier Content Centre" (click on the "Web" button top menu) there are some manufacturers of pumps listed.
