Is The Handy well Pump Easy To Pump?

Our pumps are designed differently than most other hand well pumps on the market making them very easy to pump.
Most Other Pumps...
Most other pumps require that you fill the outer pump casing with water by pumping it full and then you get what comes out the top. This type of pump was very common in windmills as far back as 150 years ago. Even the newer hand pumps that claim to be modern and streamlined use this old method of retrieving water. After all, it works. The downside of this type of pump is you have to lift the entire weight of the water inside the pump casing. This can be a considerable amount of water if you are down over 100'. Let's do the math. A standard pump extension pipe that is 1-1/4" in diameter holds .064 gallons of water per ft. at .53lbs. per ft. The water volume isn't important. What's important is the weight of the water. If you multiply .53lbs x 100' you end up with 53lbs of water that you are trying to lift with each upstroke. This requires either a long extension handle and/or a very strong back. It's why windmills were made with 16' diameter heads for deeper wells. They needed a lot of torque to move the water. Hows that for easy to pump?
Handy Well Pump....
The Handy Well Pump is designed so that the water is forced up the center riser pipe as you push down on the TEE handle or lift up on the lever. This riser pipe that is connected directly to the piston at the bottom of the pump is 1/2" in diameter. Using the same calculation as above, a 1/2" pipe holds .010 gallons per ft. or .09 lbs per ft. .09 lbs x 100 ft. = 9lbs. Wouldn't you rather push 9 lbs of water from 100' than lift 53 lbs. from that depth? Wouldn't that be much more easy to pump that filling the outer pipe with water?
It's So Easy To Pump You could call our pump child's play.
There is another factor at work here that reduces the amount of effort needed for our pumps even further. Since there are no seals in our pistons the outer extension pipe also fills with water up to the weep holes as you pump. This water in the outer pipe serves to create buoyancy in the inner riser and the weight is reduced by about 1/2 . The seal-less piston is good down to about 200'. After that there isn't enough head pressure to deliver water to the surface. For applications deeper than 200' using or HWP-L we have a specially designed piston that can force water from deeper than 300'  or act as a suction pump for small diameter openings. Either way it is very easy to pump.
