Product Information and proccess
As the piston starts downward, the check valve on the bottom of the cylinder closes and the valve in the piston opens to allow the piston to move to the
bottom of the cylinder. Water is trapped in the pump cylinder during the down stroke of the piston, and then is forced upward into the drop
pipe on the next up stroke. The pump stand in the Region One standard hand pump drawing has a drinking fountain and hydrant instead of a spout.
A reservoir on the pump stand holds a small amount of water to allow the water to flow out of the drinking fountain for 5 to 10 seconds after pumping is discontinued.
Another pump stand that is available has provisions for treating the water discharged from a hand pump.
The manual shows a pump stand with a water treatment base. The water flows out of a fitting at the pump base, through the treatment unit, and back into the bottom of the reservoir
unit. Treatment could include filtration, disinfection, ion exchange, etc.
