Hi Jim:
I'm looking at using the M267 to move the water from a basin that will catch flow from 5 gutter downspouts. What is the duty cycle rating? When it rains, I expect this pump will run continuously and/or have lots of starts.
Answer
Kind of a tough question to answer because the Duty Cycle is based on a number of variables.
Basically the standard stop/starts per hour recommended for the M267 are 6-10.
To calculate a more specific Duty cycle you would need to know the fixture count & GPM’s feeding into the basin, the basin capacity along with the collected volume capacity within the basin, also the discharge length and head, taking into account peak Vs. non-peak usage (yes it gets complicated).
There are mathematical equations to figure out a close Duty Cycle predicated on the info I just listed above however, depending on peak, non-peak or moderate demand the Duty Cycle will fluctuate.
