Windmill Aerators, accessories and parts

Outdoor

SKU: OWS

When electricity does not reach the dugout or you want to aerate the back pond, consider wind powered aeration. Canadianpond.ca carries the Outdoor Water Solutions (OWS) line of windmill aerators that feature the new BalCam II Compressor technology that minimizes bearing fatigue.

Technical specifications

When the wind resource is reliable, you will have years of free aeration using the wind and Outdoor Water Solutions (OWS) windmill technology. All Outdoor Water Solutions windmill models can be custom coloured with 2 designer selected powder coated colours (red, black, white, yellow, green, bronze, silver and blue), contact us for prices and ordering.

Vertical Well PumpsVertical Pump for well

1. Submersible Well Pump (#EOPVERTI6.25).  With a diameter of 15.88cm (6-1/4″) and a length of 154cm (60″). This well pump transfers water from a well to a pond, stock tank, or other remote location. Designed for hand dug wells or wells with minimum 16.5cm (6.5″) casings. Will pump up to 11 LPM (2.9 GPM).

Our air-driven pumps are perfect for remote water pumping needs. Works with OWS and other brand windmill aeration systems.

Requires at least 1.8m (6′) of water and 5 to 8 km/h (3 to 5 mph) winds for effective operation. PVC casing, brass check valves, and only 3 moving parts ensure low maintenance.

This pump produces up to:

  • 12.2 L/min (3.2 gallons/min) at 3.05 m (10 feet)lift
  • 9.6 L/min (2.5 gallons/min) at 6.1 m (20 feet)lift
  • 7.3 L/min (1.9 gallons/min) at 9.15 m (30 feet)lift
  • 5.1 L/min (1.3 gallons/min) at 12.2 m (40 feet)lift

2.- Gravity Water Pump (#EOVERTI2).  This pump is designed for 2″ and larger water wells, cisterns or even pumping out of a pond. Uses air pressure to lift the water to the surface and out the discharge hose. This air pump has zero moving parts and is made out of 304 Stainless steel so will last virtually forever. These pumps Vertical gravity pump for windmillwork on a submergence principle, the greater the submergence, the higher the discharge rate.  Works with our wind driven & electric aeration systems.

The amount of water pumped is based on how much of the pump is submerged in the well or cistern.  The charts below allow you to calculate the PSI required and the output in GPM.  You need to know 2 things to do the calculations:

  • How deep is the well or cistern?
  • Where is the water table?

If the well was 60 feet deep and the water table was at 25 feet, the PSI required if you put the pump on the bottom would be (60-25)/2.31 = 15.15 psi.  Submergence would be 35 feet, giving you a 58% submergence and a 4.0 GPM pumping rate.   The maximum PSI produced from most windmills and electric aerators is around 25 or so psi.

If you had a 150 foot well with the water table at 70 feet, the psi required would be (150-70)/2.31 = 34.6 psi which is beyond the rated output

Horizontal Pump for windmill

range of our systems.  You could put the pump at 120’and only use 21.6 psi, which would work . (120-70)/2.31 =  21.6 psi.   You would have 42% submergence ((1- (70/120) allowing you to pump about 2.9 GPM.

Horizontal Water Pump (#EOPHORIZ)

Even in shallow water conditions, this horizontal pump has the ability to send water to where it is needed.
Horizontal Water Pump Diameter: 23cm x 56cm (9″ x 22″ ), requires a minimum water depth of 24″ for effective operation.

Freeze Control System

Your windmill should be equipped with the Freeze Control System if you are to provide aeration to your pond during winter.  This system protects your air Line from freezing in the cold winter months.Windmill anti-freeze system

The freeze control system is self-regulating and monitors changes in line pressure. If there is a blockage, it automatically squirts non-toxic ethanol into the air line to un-freeze any blockage that may exist in freezing temperatures.
