Strong, powerful wheel, round wheel arms screw into the hub and lock into position to form a rigid wheel of strength without the use of bolts in the hub
Sails are heavily galvanized, are the right quantity (19) and have the correct curvature to develop great power even in light breezes.
Replaceable bearings. Babbitt bearings run with nominal friction, take abuse, are long lasting and are proved the most effective for windmills with multiple sails. Bearings and moving parts are readily accessible.
Balanced Operation. Large, double gears, pinions and pitman arms balance the load for efficient operation and minimum wear. Frictionless guide wheel keeps the pump rod aligned.
Two strokes. Gear and pitman arms are designed for easy change to the short stroke for greater pumping depth.
Tower construction. Built to last. Heavily dip-galvanized after fabrication.
Top corner posts wrap around the strudy mast pipe and dovetail to assure strength, rigidity and even load distribution to heavy corner post.
Girts and roud braces are accurately gauged to take the guesswork out of assembly and give equal tension to each section.
Heavy horizontal girts at seven foot intervals simplify sectrion-by section assembly.
Positive lubrication. Bearings and gears are constantly flooded with oil. Large oil ring picks up oil from large gear to keep upper bearings lubricated.
Self regulating. Regulation is automatic to protect equipment in high winds. Manual furling device is below the mill, outside the tower and has no contact with moving parts.

Capacities are approximate and based on the mill operating in winds as shown below. The short stroke increases pumping elevation one-third and reduces pumping capacity one-fourth.
in 5,4 m/s winds, capacity is reduced about 20%; in 4,5 m/s winds about 38%.
If prevailing winds are low, use of a cylinder smaller than shown will permit your mill to operate in lower winds.
Never use pipe smaller than the size specified for the cylinder. For depp wells use ball valve or Marcy cylinders with ash rod or other type of floating pump rod.

- Divide average daily water consumption by 5 to arrive at equivalent hourly pumping capacity required from your mill. This is based on wind conditions permitting your mill to pump the equivalent of about 5 hours of rated capacity per day. Naturally, this varies by locality.
- Choose the cylinder diameter that is closest to the equivalent hourly pumping capacity by using the Table of Capacities.
- Figure the total pumping elevation from the water level in the well to the poing of discharge.
- Choose the size mill to operate the cylinder when pumping to the total elevation by using the Table of Capacities.
- Choose a tower that will place the center of the wheel at least 15 feet above wind obstructions within a raius of 400 feet.
- Choose cylinder with a troke at least 2 inches longer than the pumping stroke of the mill.
- Choose pump rod, pipe and other accessories to sizes recommended for the specific cylinder.
This is a general guide. Ask your dealer to assist you in choosing the equipment tat best fills your specific pumping requirements. |
