Flint

Flint submersible filterpumps are compact all-purpose submersible pumps with a built-in self-cleaning intake. They are robust medium-head, multi-stage pumps with an integral self-cleaning suction intake.  Not only that, they screen dirty water as they pump - the self-cleaning intake protects against blocking.

They offer a maximum of 63 US GPM for the smaller FFB480 model and a maximum of 79 US GPM for the larger FFB800.  Maximum head ranges from 36 ft to 54 ft.

Flint filterpumps are made of wear-resistant rubber and ductile iron for durability. Typical uses for Flint filterpumps are:

• filtering and pumping water from dirty lagoons
• Irrigation from lakes, ponds or rivers for irrigation
• cooling water
• screening water in open loop heat pump systems
• Rainwater harvesting

These filterpumps are ideal for screening and pumping raw water for irrigation and industry, small open loop water source heat pump installations, screening industrial process water and more.  For best performance, make sure that there is good clearance around the filterpump mesh so that back-washed debris can disperse, and that the filterpump is above any silt or sludge that may accumulate.

The smallest weigh in at 37 lbs, the largest at 45 lbs. Flint filterpumps can be suspended in tanks, sumps or ponds. They can be suspended from floats or buoys, or raised and lowered on a guide-rail system.

Rotorflush Filters Ltd are happy to advise and comment on siting and installation.

There is no such thing as an entirely maintenance free filter but Flint filterpumps, in keeping with all Rotorflush filtration products, are designed for low maintenance hassle-free use.  

The nylon mesh inserts are easily replaced, and stainless mesh can be cleaned with a pressure washer. There is a trade off between mesh size and maintenance - how often depends on your mesh size and what you are filtering.

As a minimum we recommend the following:

• Mesh up to 115 micron should be cleaned or replaced every 1000 hours of use
• Mesh up to 315 micron should be cleaned or replaced every 5000 hours of use
• Coarse mesh that is 1 mm or bigger should be inspected and cleaned every 6 - 12 months

Full maintenance guidelines can be found in the instruction manual available from the download link above.

All our products are guaranteed for a year. However, as a condition of our guarantee, and to protect against dry-running, we recommend the use of a starter panel or control panel capable of cos phi load monitoring when running three-phase filterpumps.
