Water Piston

1. The water piston rotates and reciprocates. As the piston is pulled back and the piston flat opens to the inlet port, suction is created and fluid fills the pump chamber.

2. The inlet port is then sealed and crossover occurs. As the inlet port is sealed and the pump chamber is full, the outlet port opens up. Only one port is open at any time and at no time are both ports interconnected.

3. The piston is forced down and the piston flat opens to the outlet port. Discharge is created and fluid is pumped out.
