Hydraulic systems energy, saving

This evaluation does not consider the advantage of the hermetical sealing, the system s safeguarding ability of the PDP and the fact that hydraulically actuated Diaphragm Pumps are saving energy due to their better overall energy efficiency. 

Saving in Labor and Energy Scientific design of the system using principles of hydraulics would require labor only to start and stop the operation and less energy for pumping less water at lesser pressure than open-field system.
