FAQ's
for Standard Submersible Dewatering Pumps
-
What type of water are these pumps designed for?
Remko RSW Series pumps are designed for dirty water commonly encountered on construction, mining, quarry and industrial sites. For heavy slurry, fibrous solids or larger solids, another submersible pump range may be more suitable.
-
How do these pumps handle abrasive conditions?
The RSW Series uses a High Chromium impeller and suction cover case hardened to Rockwell 60C to provide abrasion resistance in dirty-water applications.
-
Can these pumps operate at low water levels?
Yes. The RSW Series is designed for low-water-level operation, making it suitable for pits, sumps, trenches and confined drainage areas.
-
Are agitator-equipped models available?
Yes. Suction agitators are available on selected 1.5–3.7 kW models to help keep solids in suspension during pumping.
-
How do I select the right RSW dewatering pump?
Selection depends on the required flow, discharge head, outlet size, solids content, abrasion level, electrical supply and operating conditions. Allflo can help match the correct RSW model to the duty.
