Sapphire 400 Filterpumps™

Our Sapphire Filterpumps™ are high pressure multi-stage submersible filter pumps with a built-in self-cleaning suction intake. This allows high-pressure, low-maintenance pumping in difficult water conditions.  Durable and robust, these filter pumps are cast iron and stainless steel construction.

These filter pumps provide high head flow rates from up to 50 m3/hr, 220 US GPM. The powerful three-phase motors have thermal overload protection, and the intake screens are available in a range of mesh sizes.

Typical uses for Sapphire Filterpumps™ are:

• Wash water for wastewater trash screens
• Wash water for raw water intake screens
• Irrigation
• District and other heat pump systems
• Anywhere you need high pressure screened water.

These filter pumps are ideal for screening and pumping quarry run-off, industrial process water, raw water, seawater and general heavy industrial uses. 

The filter pumps have a weight range from 84 kg - 313 kg, lifting gear is required to move them. These filter pumps can be suspended in tanks, sumps or ponds or from buoys, or raised and lowered on a guide-rail system.

For best performance, make sure that there is good clearance around the filter pump mesh so that back-washed debris can disperse, and that the filter pump is above any silt or sludge that may accumulate.

There is no such thing as an entirely maintenance free filter, but Sapphire Filterpumps™, in keeping with all Rotorflush filtration products, are designed for low maintenance hassle-free use. Easy to pressure wash stainless steel mesh and in-built thermal protection in the filter pumps ensures smooth running.  

The stainless mesh should be cleaned with a pressure washer. There is a trade-off between mesh size and maintenance - how often depends on your mesh size and the quality of what you are filtering.

As a minimum we recommend the following:

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

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 these filter pumps.
