Topaz Range 600AR Filterpumps

From £13,065.00

Rotorflush Topaz 600AR filterpumps are general pupose high capacity medium head filterpumps, suitable for many industrial and agricultural applications.

Their 600mm diameter stainless steel self-cleaning intake screen can be manufactured from 304 or 316 stainless steel.  The powerful three phase motors have a thermal cutout and the intake screens are available in a range of mesh sizes.

These filter pumps deliver up to 2500 litres a minute and provide the same low maintenance and efficient intake screening of all our submersible filterpumps. Mesh sizes range from 315 microns to 3mm.

Using Rotorflush's unique self-cleaning intake filter technology the Topaz range of filterpumps deliver an uninterrupted supply of water while a continuous backwash keeps the intake, pump and other downstream equipment blockage free.

Models & Specification

Topaz Range 600AR Submersible Pumps with Built-in Self-cleaning Intake Screens

The Topaz range is a range of industrial low to medium pressure self-cleaning submersible filterpumps offering up to 1800 litres per minute (108 m3 / hr).  The Topaz Range 600AR filterpumps are very robust, they have a cast iron upper cover, a strengthened AIS1304SS motor case and a chrome steel impeller.  The stainless steel self-cleaning intake lets you combine pumping and screening from source without the screen or pump blocking. They are ideal for screening and moving large volumes of dirty water.

Topaz range 600AR filterpumps have self-cleaning intakes that prevent debris entering the pump and keep debris off the filter screen. They can be fitted with a range of mesh sizes:

  • 315 micron stainless steel sintered filter mesh
  • 1 mm or 2 mm woven stainless steel mesh
  • 3 mm perforated steel mesh.


The Topaz range filterpumps are suitable for heavy duty use and can be manufactured with 316 stainless steel self-cleaning intakes made with 316 stainless steel. All our filter mesh is 316 stainless steel. Stainless steel mesh is ideal for more challenging environments.

Topaz Range submersible pumps have three phase motors and are fitted with self-cleaning suction intake screens.

NB: It is very important that three phase motor filterpumps are connected to their power source correctly, to ensure that the pump motor runs in the right direction. When pumps run backwards they are inefficient and the motor may be damaged. To see how to test that the pump is wired correctly watch this video.

Please note that we strongly recommend the use of Control Panels and / or a Din Rail mounted Cos Phi Load Monitor with all 3 phase models to prevent damage to pumps.

Installing adequate load monitoring is a condition of our guarantee for these products.
