Wet Prime Pump & Dry Prime Pump Comparison
What Are The Differences Between Wet Prime And Dry Prime Pumps?
- Wet prime pumps (often called ‘self-primers’) require the casing to be filled with water prior to the first start-up only. After that, the liquid will always remain in the pump volute, so the suction hose can run dry without damaging the pump or seals
- Dry prime pumps are end suction pumps that can run completely dry since the mechanical seal is lubricated in its own separate oil reservoir . It is unable to prime on its own , thus requires a compressor that creates vacuum through a venturi educator to evacuate the air and prime the pump
Wet Prime Pumps

- Easier Maintenance
- Fewer moving parts
- Long-lasting reliability
- Less expensive than dry prime
- Does not need compressor or venturi to prime
- Can handle solids up to 3”
- Self-Priming up to 25’
