Shree Ram Pump & Pipe

Pumps that are partially or completely above the fluid level allow air into the suction line, which must be evacuated or displaced before the pump can move the liquid. Self-priming pumps are capable of removing air at startup before beginning its normal pumping functions.

To avoid the mixing of air and water, self-priming pumps create a partial vacuum to discharge water while also evacuating any air. It does this by combining the air and water during the priming process, forcing the air to rise and the water to sink or go down. Gravity then pulls the air-free water back into the impeller, where it mixes with the remaining air in the suction line.

This process repeats until all air is evacuated and a vacuum forms in the suction line. Once this happens, atmospheric pressure forces the water into the suction line and towards the impeller to allow pumping to begin.

• Entrained Gas Handling – Due to their ability to vent suction lines they can handle fluids with entrained gasses, priming for up to 30 mins without drawing liquid.
• Easy to Maintain – They are far easier to maintain than a submersible pump which is immersed in the liquid and may need confined space training to maintain.
• Reliable – Their designs are not based on use with other accessories meaning they do not rely on additional valves to function which can sometimes fail
• Robust – As the motor and cable are not immersed in fluids, they are longer lasting and less exposed to pumping mediums when handling corrosive or aggressive fluids
