Can this pump handle side loads as in a pulley application? Also, what horsepower is required to operate this pump at 3600 rpm?
1 answer-
NorTracExperts· 9 years ago
This will require an external bearing support to support belt loading. To determine the HP required use the following formula: Flow rate (GPM) x system pressure (PSI) / 1714 x % pump efficiency.
