Simple Hand Well Pump
Pumping water from the ground can be abrasive. Most Other Pumps...
In many situations where water is being pumped from wells where there are suspended solids, a pump with traditional seals can be ruined in short order. A few grains of sand can have you pulling your pump up from 100'+ and then trying to figure out where and how to get your simple hand well pump back in operation without waiting a week for some special proprietary seals to appear. Or, in a lot of cases how to replace the outer cylinder that has become damaged by the seals dragging sand into its smooth surface. This isn't a problem with The Handy Well Pump. It's unique piston design uses the water itself as the seal. The inside of the pump never needs any maintenance.
The Handy Well Pump...
...is a simple hand well pump by design and operate flawlessly, with every stroke. The image shows how water is pumped through the piston and gets to the surface under pressure. Its simple foolproof design insures that it will always work, and always supply water when you need it with just a stroke or two of the handle, whether your water is at 20' or 150'. With our pumps there is no need to continuously spend time bringing water to the surface because of the drain down of a large diameter pipe to weep hole level. You are only bringing water up to the surface in the center 1/2" riser pipe so it is delivered quickly and in a larger volume and higher pressure than if it were in the outer pipe.
The Patented Handy Well Pump Piston
The most important feature of this simple hand well pump is that it doesn't use any seals. To put it more accurately it uses the water itself as the seal. The outer surface of the piston has what we call Turbulence Rings TM cut into it along the surface of the piston. This creates a situation where, when the pump is in the downward stroke and water is being forced between the piston and the cylinder wall, turbulence is created to keep the water from going by the piston on the outer surface. Water is instead directed through the piston and up the center riser pipe at considerable force. If small sand particles get between the piston and the cylinder wall they are usually just moved along without any damage because of the gap between the piston and the cylinder. If it is a large enough particle to get lodged and scratch the surface it will not normally impair the function of the pump in any significant way. The worst that can happen is that the pump would need to be removed for cleaning. Since everything is threaded together, this can be accomplished in less than an hour for a 100' well. The pump itself is easy to take apart and service.
