plumbing -- what is the difference between a jett pump and a shallow well pump?

Answer 1

They name and the way they are made is the only difference.
One works off centrifugal force and the other works off a jet assembly. Jet assembly will greatly increase the discharge pressure and suction. more so than the other style pumps.

Shallow well vacuum pumps are designed to extract water from cisterns and from wells no deeper than 25 feet.

They can be either centrifugal pumps or jet pumps but jet pumps are more common.

Centrifugal pumps are designed for low suction heads (vertical lifts) and high capacities. As a rule they develop low pressures, usually 45 to 55 pounds per square inch maximum.


Pumping action is created by a means of a high-speed impeller that literally throws the water or mixture out of the pump by means of centrifugal force.

Answer 2

They could both be the same and, in fact one type is a "convertable" while one goes down into the well, forever pumping your water, the other is on top, usually a shallow well, like twenty, fifty feet deep, the other is like two hundred feet deep.
