NOTES:
1.
All flows are continuous operation 24 hours/day - 7 days/week.
2.
Based on water with a specific gravity of 1.0 and specific heat of 1.0
3.
Pumps can be operated reliably at lower minimum flows under intermittent operating conditions. Contact
Goulds Pumps. Intermittent Operation = operating under these conditions less than 15% of the time.
4.
Contact factory for pump efficiency at minimum flows.
5.
Can be operated at substantially lower flows with adequate NPSH margin. Contact Goulds for details.
