Description / Heller Aller Windmill Double Acting Force Pump Model 50L
Please Note. These pumps are in very high demand. The small factory that builds them sometimes struggles to maintain sufficient parts from a local foundry to fill all current orders immediately. At times, they may have a 1-3-week delay before new parts arrive.
The pump fits inside a 3-inch or larger well casing, eliminating the unsanitary, undesirable false well pit. The well casing can be securely capped and sealed to prevent ground-level contamination.
Stainless Steel ½” sucker rod down to the attached lift cylinder.
Adjustable for either a 4”, 6”, or 9” stroke.
Available in 4” or 6” caps or a platform base.
Anti-freeze 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 is required to pump water on both the up and down strokes. An additional lift cylinder will be needed to raise the water from the well. This pump is classified as a deep-well pump, although many use it for shallow-well applications due to its force capabilities. Each application varies in well depth. The piping and sucker rod required to reach the lift cylinder are also not included. Please email us your well casing size, depth, and static water level so we can provide a quote for the lift cylinder you need. Our lift cylinders are brass with 1-1/4" inlets.
