Never install a pump with the can pointing up. Most Taco pumps and Grudfos pumps are water lubricated and most pressures in residential heating systems will never overcome the 20 psi constant to lubricate the cartridge. This can make the pump seize forcing you to replace the cartridge earlier than under normal operation.
Taco pumps, Grundfos pumps, and many other pumps and flanges can be found at www.supplyhouse.com
