A centrifugal pump that can extract liquid from a level beneath its suction port without the need for an external priming assistance is known as a Self Priming Pump.
How Self Priming Pump Works?
- The self prime pump can reprime itself in lifting conditions thanks to its special design.
- Without the need of external tools, these pumps remove air from the pump suction line and raise fluids from a level underneath the pump.
Types of Self Priming Pump
One of the most effective kinds of pumps is the self-priming pump. Priming these pumps by hand is not necessary. Air pressure and gravity in the self-priming pump keep air out of the suction line or pump and guarantee that there is always enough water in the pump cavity.
Dynamic Pump
- A dynamic pump transfers the fluid by increasing its pressure as it passes through the impeller and diffuser of the pump. In this type, the impeller increases the speed of the fluid and the diffuser converts this speed into pressure energy. It uses centrifugal force to transfer the fluids.
- A dynamic pump further divides into the below-given types:
- Centrifugal Pumps
- Special Effect Pumps
FEATURES
- Efficiency at par with internationally available pumps.
- Quick automatic self-priming action. Designed for automatic air release during priming.
- Non-clogging impeller to handle suspended solids.
- Repairs possible without disturbing the pipe connection due to back pull out design (except ASP’0’).
- Portable, when fitted on trolley/trailer.
- Suitable for engine / motor.
- No need for foot valve.
- Long life-Due to replaceable wearing parts.
- Dynamically balanced rotating parts ensure minimum vibrations.
- Easy maintenance and spares availability.
APPLICATIONS
- Marine-Pumping water from Docks, Ports, Vessels.
- Industrial Petroleum products, Chemicals, Effluents, Sewage, Ash-water etc.
- Civil construction: Dewatering foundation, trenches and pits.
- Mobile Machinery: Cooling water for Marine Engines and Shovels.
- Public utilities: Sewage pumping.
