FAQ's
for Submersible Sludge & Slurry Pumps
-
What types of material can these pumps handle?
Remko RSS pumps are designed for abrasive, viscous and solids-laden fluids, including sand, sludge, slurry and industrial wastewater.
-
What does the integrated agitator do?
The chrome-alloy agitator helps loosen settled material and keep solids in suspension during pumping.
-
What performance capacities are available?
The range includes models delivering up to 500 L/min at 25 m maximum head and up to 1,000 L/min at 30 m maximum head.
-
Are these pumps suitable for continuous operation?
The submersible design supports ongoing operation, but suitability depends on the selected duty point, liquid characteristics and installation conditions.
-
Can these pumps handle corrosive liquids?
The RSS Series is designed primarily for abrasive and viscous fluids. Chemical compatibility should be confirmed with Allflo before use with corrosive liquids.
-
How do I select between the two models?
Selection depends on required flow, discharge head, solids concentration, abrasion level, submergence depth and available power supply.
