Injection wells use high-pressure pumps to inject liquid wastes into under-ground geologic formations (e.g., sandstone or sedimentary rocks with high porosity ). Many geologists believe that wastes may be isolated from drinking water aquifers when injected between impermeable rock strata. However, ...
A pump for pumping water from wells has a piston which is a clearance fit on a bolt onto the end of the piston rod. On the down-stroke, the upper end of the piston abuts against the end face of the rod, but on the up-stroke, the lower end abuts against the nut. As the piston...
