Wet Prime Pumps
Allflo supplies the Remko RS Series wet-prime self-priming pumps, known for compact, reliable performance in handling water and light solids across civil and industrial applications.
These pumps use a wet self-priming centrifugal design — once initially primed with water, they will automatically re-prime during operation, providing dependable suction performance in variable site conditions.
The RS Series prioritises ease of maintenance and portability. Their robust construction requires minimal servicing while delivering strong pumping output for tasks such as construction dewatering, stormwater management and agricultural water transfer.
- Self-priming bowl retains prime between cycles
- Durable construction for civil & industrial duties
- Strong solids-handling for mixed wastewater

FAQ's
for Wet Prime Pumps
-
What makes wet-prime pumps different from dry-prime pumps?
Wet-prime pumps retain liquid inside the casing to enable rapid self-priming and reliable re-starts without external priming systems.
-
Can wet-prime pumps handle solids?
Yes — they are designed to handle moderate solids and contaminated water typically found in construction and stormwater applications.
-
Are wet-prime pumps suitable for continuous use?
Wet-prime pumps are widely used for ongoing civil and industrial operations where stable, repeatable suction performance is required.
-
Can these pumps be paired with diesel or electric drives?
Yes — RS Series pumps can be configured into diesel, electric, hydraulic, or PTO-driven packaged pumpsets.
