Rotorflush Opal SH800 Filterpumps™

Opal LH800 submersible filter pumps are medium head, industrial use, centrifugal pumps with a self-cleaning filter on their suction intake. They benefit from a cast iron pump casing, and a stainless steel, built-in, self-cleaning filter which protects against blocking while pumping.

The Opal LH800 filter pumps are three-phase, dirty water pumps whose tough build and high-grade materials give exceptional performance in harsh operating conditions. These filter pumps have a double mechanical seal, and the top discharge design forms a water and air-cooling channel. Opal LH800 Filterpumps™ feature thermal protection, enabling simple installation and direct connection to the power supply. 

Opal LH800 filter pumps combine pumping and screening up to a maximum of 408 m3/hr, and a maximum head of 230 m.

These are heavy-duty industrial filter pumps. Typical uses for Opal LH800 Filterpumps™ are:

• Mining industry drainage
• Irrigation from lakes, ponds or rivers for irrigation
• Pumping stormwater and floodwater
• De-Watering Slurry Lagoons and Dirty Water Irrigation
• Screening industrial process water for re-use or disposal

316 Stainless Steel woven mesh

A tough, coarse screen provides the best maintenance schedules. Filter pumps with coarse mesh come fitted with rubber backwash jets, which are suitable for handling larger particulate and debris.

Available in 1 mm, 2 mm and 3 mm.

These filter pumps are ideal for screening and pumping raw water, clean or dirty water irrigation, pumping in harsh environments, and general heavy industrial uses. 

The Opal LH800 Filterpumps™ weigh up to 1578 kgs, 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.

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

There is no such thing as an entirely maintenance free filter, but Opal LH800 Filterpumps™, 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 what you are filtering.

As a minimum, we recommend the following:

• The stainless steel mesh 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 filter pumps.
