GLOCKEMANN PUMPS WORK
The Glockemann pump has three phases in its operation Due to gravity water flows down the drive tube, through the diaphragm chamber and out the exhaust valve. The water speed increases as it moves down the drive tube, and after about two seconds, the flow builds up enough force to trigger the exhaust valve to slam shut, just like a door slamming shut in the wind. CHARGING STAGE |
 |
| With the exhaust
valve shut all the water in the drive tube comes to a sudden stop. This
results in an expansion of the diaphragm, which causes the piston
to move forward in the cylinder or ‘bore’, forcing water
through a non-return valve and up the delivery pipe
PUSH STROKE |
 |
| At the end of
this stroke the water in the drive tube has used up its momentum, and as
a result the pressure in the diaphragm chamber drops. This allows the
exhaust valve to spring open. With the exhaust valve open the return
spring pushes back the diaphragm resulting in the return stroke.
This causes the piston to pull back in the cylinder and draw water
through another non-return valve into the cylinder.
