Opal SH400 Filterpumps™

Industrial Submersible Water Pumps with a Built-in Self-cleaning Suction Intake Screen used for pumping dirty or contaminated water.

Our Opal SH400 Filterpumps™ are based on the successful Tsurumi LH and LH-W ranges of pumps.  Opal SH400 Filterpumps™ have a hard ductile iron casing and a cast iron motor frame; the self-cleaning intake is all stainless steel.  

These filter pumps provide medium to high head flow rates  up to 1 m3 / minute, 265 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 Opal Filterpumps™ are:

• Mining 
• Quarrying
• Heavy Industry 
• Anywhere you need a tough, durable filter pump.

Rotorflush Opal SH400 submersible filter pumps have integral self-cleaning intake screens, offer fine or coarse filtration, and provide the same low maintenance and efficiency shared by all Rotorflush products.

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

The filter pumps have a weight range from 65kg - 329 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 Opal SH400 filter pumps, in keeping with all Rotorflush filtration products, are designed for low maintenance hassle-free use.  

The 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 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.
