If you’re not planning on ever using the electric submersible pump, go ahead and have it removed by a professional pump installer.

However, with the right conditions, well pump installers can install manual pump cylinders within a well casing that has an existing electric submersible pump. This is a common practice. Even though your well is 400’, your static water level could be 250’ or less.

With such deep wells, a 1 7/8” open-top cylinder is best to use because when the pump leathers need replacing, the sucker rod and cylinder can be removed without removing the drop pipe. This access makes it much easier to replace the cup leathers.

Just like other hand pumps, the WaterBuck Pump also can be installed with an existing submersible pump. Again, if you’re not going to hook up to electricity, it would be best to have the old pump removed.

Even though you have a 6” pipe, you would need a 1 7/8” cylinder because of the force required to pull up water from that depth. There are other hand pumps on the market that claim they reach depths of 350’, but pump installers have told me it is not practical to use common hand pumps at that depth except for emergency use.

The peak performance of a 12-foot windmill operating a 1 7/8” cylinder at 390’ is 3 gpm. The WaterBuck pump exceeds the gpm output of a 12’ windmill at its maximum depth of 86’, so we anticipate 3+ gpm at 390’.

We are making another significant mechanical advantage addition to the pump that will make it even easier to operate and reach deeper. We will have another video demonstration soon. So, stay tuned.

The WaterBuck Pump is not expensive compared to windmills and solar pump systems. It is a solution for getting water without wind power and electricity from deep wells. It is also made to last for generations. You can view a sample price at the following link. http://waterbuckpump.com/sample-price/
