What Are Self Priming Pumps?
Self priming pumps are centrifugal pumps designed with an internal priming chamber that retains liquid after shutdown. This retained liquid allows the pump to re-prime itself when restarted—eliminating the need for manual priming or vacuum systems.
Unlike standard centrifugal pumps, which require a completely flooded suction line before starting, self priming pumps can evacuate air from the suction line and pull fluid up into the casing automatically.
How Self Priming Pumps Work
The secret lies in the priming chamber, which holds a volume of liquid after the pump stops. When restarted, this liquid mixes with the incoming air in the suction line. The mixture is then discharged through the impeller, with the air expelled and the fluid re-circulated until full prime is achieved.
Once primed, the pump functions like a standard centrifugal pump—efficiently moving liquid with minimal pulsation.
Applications of Self Priming Pumps
Self priming pumps are widely used across Australian industries for their simplicity, versatility, and reliability:
- Construction & Dewatering – Portable pump sets for trenches, pits, and stormwater removal
- Agriculture & Irrigation – Lifting water from tanks, creeks, or bores
- Mining & Quarrying – Handling slurry, sediment, and site runoff
- Wastewater & Utilities – Pumping raw sewage, sludge, or chemical effluents
- Industrial Processing – Transferring liquids where line priming is difficult
- Emergency Services – Mobile firefighting or flood response units
Wherever a fast start and no-fuss operation is needed, self priming pumps get the job done.
Benefits of Self Priming Pumps
✅ No External Priming Required
Saves time, labour, and the need for extra equipment like vacuum pumps or priming tanks.
✅ Dry Start Tolerance
While not meant to run dry long-term, they can handle limited dry operation without damage, especially during air evacuation.
✅ Ideal for Portable & Remote Installations
Perfect for trailer-mounted systems or locations without easy access to tools or water sources.
✅ Handles Solids and Slurries
Certain models are designed to pass soft solids, making them great for dirty water, sewage, or thick fluid applications.
✅ Easy Maintenance
Front pull-out designs, inspection covers, and simple part replacement reduce downtime.
Self Priming Pump Types Available at MultiTorque
We supply a wide range of self priming pumps in various materials, configurations, and capacities:
🌊 Self Priming Centrifugal Pumps
Great for general water transfer, stormwater dewatering, or tank filling. Available in cast iron, stainless steel, or corrosion-resistant materials.
💩 Trash & Sewage Self Priming Pumps
Specifically designed for handling solids up to 75mm, commonly used in wastewater, sewage, and mining sites.
💧 Chemical-Resistant Self Priming Pumps
Built with materials like PVDF, polypropylene, or Teflon for aggressive chemicals, acids, and alkalis.
🔥 High-Pressure Self Priming Pumps
Used in firefighting and washdown applications where high head and fast deployment are essential.
Key Features to Look For
When selecting a self priming pump, consider the following factors:
- Priming Lift – Maximum vertical distance the pump can lift fluid on startup
- Flow Rate & Head – Match pump performance to your system requirements
- Solids Handling – Required for slurry, sewage, or sediment-heavy fluids
- Material Compatibility – For corrosive or abrasive applications
- Portability – Trailer mounting, fuel tank integration, or skid-base
