The Shaw hand pump described here has only been designed in detail but has not been produced. It is presented here as informational only, on which orders could be made.
WELLS
​
awkward location installation
Because Shaw domestic water supply or monitoring wells are installed with man-portable Shaw diamond core drills, these can be installed in roadless, otherwise difficult of access locations.
​
low cost
The cost of advancing Shaw diamond core drill borings is minimal as are the pump components, both above-ground and at depth.
highest quality materials
Shaw pump parts, including above-ground pump body and handle, sucker rods, and downhole piston pump body, are made of 304 food grade stainless steel which is a strong steel and very resistant to corrosion. The internal parts of the downhole pump are made of 304 and Teflon for valves and balls which is an elastic material resistant to abrasion and impact.
​
reliable well seals
Sanitary seals for domestic water supply wells, although typically required by law to prevent contamination of groundwater by surface runoff, inevitably fail due to erosion of the seal’s exposed bentonite mass by ground or surface water. The plugged bentonite cartridge well seal newly invented by Shaw as part of the Gen3 suite of innovations, does not expose its bentonite sealant mass to erosion by ground or surface water.
high efficiency hand pumps
Because the Shaw two-handed pump was intended to be a sole water source tool for the supply of households where electricity for driving submersible pumps was unavailable, its above-ground pump was designed to ergonomically harness the strength of the large muscle groups of the human body, its source of power. The Shaw downhole pump parts were designed to facilitate easy passage of water around the shaped hydrodynamically shaped piston balls and through its relatively large openings valves.

FREQUENTLY ASKED QUESTIONS
Q. How deep can I bore for well installations with the use of a Shaw drill?
A. ???
Q. Can I use an electric submersible pump in a Shaw well?
A. Yes; a two-inch (51 mm) OD standard electric submersible pump can be placed in a 53 mm ID Shaw thin-walled polycarbonate tube well riser (barely, but really).
Q. Can I pump water by hand to a pressure tank in my house?
A. Yes; but the location of the adjustable handle pivot point pin must be moved inward to provide more leverage and therefore greater mechanical advantage to the above-ground pump arm.
Q. Can I advance a “deep” boring with the use of a Shaw drill and mast and install a Shaw pump in it by myself?
A. Yes; the most challenging part of the job will be completing the well boring, but once this has been accomplished the well installation itself will be relatively simply and quickly accomplished - merely a matter of threading steel pump parts together, placement of a Shaw plugged cartridge bentonite seal on the well riser at a point about five feet (1.5 m) below the ground surface, and gluing together many short sections of thin-walled polycarbonate tube and couplings.
Q. Are Shaw hand pumped wells freeze proof?
A. Yes; a tiny weep hole in the Shaw well riser tube at a level three feet (1 m) below the ground surface allows pumped water to drain away to a level below the frost line but well above the sanitary seal.
Q. Can Shaw above ground pumps be taken down and stored safely for the winter for seasonally used cabins?
A. Yes; the well standpipe can be threaded off of its base, the threaded uppermost sucker rod similarly disconnected below ground level, and a protective cap threaded down flush with the top of the standpipe receiver.
Q. What is the potential water discharge rate of a Shaw hand pump built in a 62 mm OD boring in a shallow, high yield aquifer?
A. Theoretically 10 gallons (40 liters) per minute seems likely, given a comfortable 60 pump strokes per minute pumping rate for a reasonably fit, average strength man working steadily at a Shaw pump, and 1.3 pints water discharge per stroke.
