Heller Aller Windmill Double Acting Force Pump Model 50L

Please Note. These pumps are in very high demand. The small factory that builds them struggles at times in keeping enough parts coming in from a local foundry to immediately fill all current orders. At times, they may have a 2-6-week delay before new parts arrive.

Pump fits inside 3-inch or larger well casing, thus eliminating the undesirable, unsanitary false well pit. The well casing can be securely capped and sealed against possible ground-level pollution.

Stainless Steel ½” sucker rod down to the attached lift cylinder.

Adjustable for either a 4”, 6”, or 9” stroke.

Available in either a 4”, 6” cap, or a platform base.

Anti-Freezing when the force cylinder is located four feet down inside the well casing and drained at that point. 

Purchase an optional windmill pump connector.

The price at the top of the page begins with the 4” well cap base and incrementally adjusts as options are added. 

This pump uses two cylinders, the double-acting force cylinder required to pump water on the up or down stroke is included. An additional lift cylinder will be required to bring the water up from the well. This pump is considered a deep well pump although many uses it for shallow well applications for the force capabilities it provides. Each application is different regarding well depth. The piping and sucker rod needed to go on down to the lift cylinder is also not included. Please e-mail us with your well casing size, depth, and static water level to quote the lift cylinder that you will need. Our lift cylinders are brass with 1-1/4" inlets.
