PerformancePro Cascade Low RPM Pumps

*You can purchase salt water kits at the time of pump purchase, and you need them when operating with salt water.

How It Works

When on, the electric motor utilizes centrifugal force to generate the velocity of the water to flow into the optional strainer pot if installed to filter out debris or, if not, will flow directly into the pump housing. Water continues its flow into the eye of the impeller, where the water converts kinetic energy into static pressure allowing the pump to maintain pressure. It is then forced out of the pump’s discharge port resulting in continuous water flow.

Installation Guide

*The Cascade Low RPM Pump is not self priming and is best suited for flooded suction systems. Prior to starting the pump, you must fill the pump housing and the entire suction line with water for proper operation.

Flooded Suction External Pond Pump Setup

• This ideal external pond pump setup 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 External Pond Pump Setup

• Install a Swing Check Valve for the suction lift.
• Install the Check Valve below the water level to prevent dry running and assist in priming.

Recommended Maintenance

Inspect the pump and free it of any debris at least once per week. Do not run the pump dry.

Winter Prep

In freezing environments, it is advisable to winterize your pump to prevent damage. Do not allow the pump or system plumbing to freeze.

How to Read a Flow Chart

The flow chart helps you determine how much water your project requires and the best water feature pump for the job.

Start by calculating your applications’ specific water-flow requirements, measured by Head Pressure (Feet) and Gallons Per Hour (GPH) water flow.

Aim for the Middle of the Curve:

Plot your calculation on the PerformancePro Cascade Low RPM Pump flow chart. Select the external pond pump that is in the middle third of the pump curve. Avoid being too close to either axis. External pond pumps outside the curve’s range won’t perform well for your use and will strain, shortening their lifespan

Other Considerations When Choosing a Cascade Low RPM Pump:

It’s Better to Oversize than Undersize: You are better to slightly oversize a low rpm pump than to undersize. You can install a ball valve to reduce the water to your desired flow when oversizing.

Check Your Other Equipment: Choose a low rpm pump that does not exceed your filter’s indicated maximum flow rate. Also, be sure the tubing you select can handle the flow rate of your pump.
