Performance Data
The pump performance is defined by the relationship between Total Dynamic Head (feet) and Flow Capacity (Gallons Per Minute). At 0 feet of head, the pump delivers 140 GPM. As the head increases to 25 feet, the capacity decreases to 40 GPM. The maximum shut-off head is 28 feet.
Practical help
Common problems
Pump fails to start
Verify the float switch operation. The pump is designed to turn on at 17-20 inches and off at 10-12 inches.
Reduced flow rate
Check the discharge pipe for obstructions. While the impeller is clog-resistant, ensure the discharge path is clear.
Before use
- Verify power supply is 115V, 60Hz.
- Ensure the discharge pipe is 2-inch FNPT.
- Check that the float switch has adequate clearance to operate (17-20 inches on, 10-12 inches off).
- Confirm the application is suitable for wastewater or sewage removal.
- Ensure the pump is fully submerged for continuous duty operation.
