General Information

- The Onga Silentflo SF750 Pool Pump is a product of more than 40 years of innovative hydraulic engineering

- Can move more water more efficiently for lower operating cost and super-quiet operation

- By performing with less effort, there's simply less wear and tear—and that means longer life for a higher return on your pump investment


Features

- Large volume strainer basket minimises the maintenance requirement by extending the time between strainer basket clean outs

- Includes 50mm barrel unions making it quick and easy to install, while allowing pump removal without flexing pipework

- Dual connections: 50mm thread or 50mm barrel unions allows piping flexibility - threaded connections allow for permanent installation - service is still possible by removing the motor and yoke from the casing

- Thermoplastic casing and hydraulic parts provides total corrosion resistance for long life and peace of mind

- The SilentFlo range of pool pumps have passed all the requirements of AS/NZS 60335.2.41:2004 for safety, and is approved for installation within the wetted zone of the pool area

- Captive bolts for easy servicing, no lost fasteners
