Forcing Pump

| View Cart ⇗ | Info

“As the piston ascends, as shown in the left-hand figure, the pressure of the atmosphere forces the water up the suction pipe P; the water opens the suction valve V and flows into the pump cylinder. When the piston moves down, as shown in the right-hand figure, the suction valve is closed and the delivery valve V’ opened. The water in the pump cylinder is now forced up the delivery pipe P’.” —Hallock 1905
