You guys are great. These were all "maybes" in my plans but I didn't have the engineer/physics background to realize it.
The pump cylinder will be new pipe. The seal will have to be where the tapered portion intersects with the old well casing. The gasket will be like a 2 wide rubber belt...
Due to earthquake damage (we're in the So Cal Desert) the casing has become bowed just enough to prevent using a turbine. I just think it's a shame to destroy a 50 year old well so I'm being cheap and trying to salvage it. A new well and turbine pump could cost upwards of 250k which we don't...
This is a prototype for a much larger ag pump I want to build. The 4 inch drop pipe is actually the well casing. The 2 inch pump cylinder will be tapered out to the sides of the casing. A rubber gasket will seal the sides with a Tyvek liner to the top of the casing to seal off the...
also, I was was using the term piston pump but after doing some research it looks like the term would most likely be "bucket pump" since the plunger is actually pulling the water up the pipe. I do shop work on our farm. More of a tinkerer with this stuff than a designer/manufacturer. Again...
So the weight of the 4 inch wide column of water (100 ft. tall) in the drop pipe isn't creating downward pressure on the piston? The piston pushing the 2 inch cylinder of water into the 4 inch drop pipe above only has to move the weight of the 2 inch portion? There is no check valve between...
I'm designing a bucket pump for a water well I'll be attaching a pumpjack to. I'm just a regular shop guy so I was kind of stumped on a question of how much upward pressure will be required to move the water up the drop pipe. If the pump cylinder is the same diameter of the drop pipe I figure...
