Installation Guide

Flooded Suction
• Ideal setup as it does not require priming.
• Ball Valve installed before and after the pump for ease of maintenance.
• We recommend installing a Union before and after the pump for ease of disassembly and maintenance.
Suction Lift
• Suction lift must be installed with a Swing Check Valve.
• Check Valve installation is required below water level to avoid dry running unit and aids in priming.
Maintenance
Lubrication Motor – Permanently Lubricated ball bearings – no service required.
Rotary Seal – Requires no lubrication after assembly.
Winter Care: This pump must be drained before servicing or if stored below freezing temperatures. Periodic replacement of seals may be required due to normal carbon wear.
The Flow Chart below is designed to allow you to plot your pond’s water-flow requirements, and easily determine which pond pump will meet those requirements.
Flow Chart

Aim for the Middle of the Curve:
After plotting your calculation on the Flow Chart, find a pump that falls in the middle third of the pump curve, not too close to either axis. Pumps that fall on the fringes of the curve will not work as efficiently for your application, and they will be pushed to their operating limits, reducing their life span.
Other Considerations When Choosing a Pump:
It’s Better to Oversize than Undersize: You are better to slightly oversize a pump than to undersize. When oversizing, you can always install a ball valve to reduce the water down to your desired flow.
Check Your Other Equipment: Choose a pump that does not exceed the indicated maximum flow rate on your filter or water feature. Also, be sure the tubing you select can handle the flow rate of your pump.
