There are 10 total speed settings. Each step down from full power reduces the pump’s flow by the following amounts:
- 1000DC Pump – Each step down reduces pump speed by approximately 2.5%
- 1600DC Pump – Each step down reduces pump speed by approximately 2.5%
- 2100DC Pump – Each step down reduces pump speed by approximately 3.5%
- 3200DC Pump – Each step down reduces pump speed by approximately 3.5%
