Cost-Saving Efficiency
The Little Giant Professional Series of pumps produce a maximum flow rate with minimal electrical consumption.
The dollars saved from reduced operating costs can pay for the pump in a matter of months.
Safety
The Professional Series are end suction centrifugal pumps, designed to be located on the perimeter of the
pond. This eliminates the need for wading into the pond to service the pump or pump intake filter. By locating
the pump outside of the pond, you also greatly reduce the chance of electrical shock.
Reliability
The Professional Series was designed with the professional in mind. Built tough, the pump housings are injection-
molded of corrosion-resistant thermoplastics, and are mounted to custom-built motors. Each Professional
Series pump is thoroughly tested prior to shipment. When properly installed, your pump is designed to
provide years of dependable, reliable service.
Quiet Operation
Install these pumps wherever you desire. The Professional Series was designed for water gardening, not industrial
applications, generating noise levels equivalent to a small electrical fan at 52 dB.
NOTE: For above the water level applications, a leaf basket (566106), is required to act as a priming chamber.
