JET Self-Priming Cast Iron Pumps complete of ejector and diffuser for high priming capability. Suitable for sucking from well up to 9 meter, provided in 3 different material pump body: cast-iron, stainless steel and techno polymer.
JET Self-Priming Pumps use a venturi effect to create suction and draw fluid into pump casing. They consist of a jet assembly that generates a high-velocity flow of liquid, creating a vacuum and inducing the fluid to enter the pump.
How Do Self-Priming Pumps Work?
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.
