RUBI Range Submersible Pumps

From £11,702.00

RUBI filterpumps are extremely tough heavy duty filterpumps, suitable for mining, quarrying and heavy industrial applications.  These filterpumps are cast iron with stainless steel intake filters.  The powerful three phase motors have thermal overload protection and the intake screens are available in a range of mesh sizes.

The Rotorflush RUBI Range of submersible filter pumps with integral self-cleaning intake screens offer fine or coarse filtration while pumping up to 1000 litres a minute and provide the same low maintenance and efficient intake screening of our smaller filter pumps.

As with all our products RUBIs use Rotorflush's unique self-cleaning intake filter technology to deliver an uninterrupted supply of water while a continuous backwash keeps the intake, pump and other downstream equipment blockage free.

Models & Specification

RUBI Range Submersible Pumps with Built-in Self-cleaning Intake Screens

The RUBI range is a range of industrial medium and high pressure self-cleaning filterpumps.  These all cast iron and steel filterpumps combine pumping and screening and are ideal for use in harsh water conditions.

RUBI Range submersible Pumps have self-cleaning intakes that can be fitted with a range of mesh sizes:

  • 115 or 300 micron nylon filter mesh
  • 100 or 315 micron stainless steel sintered filter mesh
  • 1mm or 2mm woven stainless steel mesh
  • 3mm or 6mm perforated steel mesh.

 

Stainless steel mesh is ideal for more challenging environments. The RUBI range filterpumps are suitable for heavy duty use and can also be fitted with 316 stainless steel self-cleaning intakes.
