This pump is more efficient that a single-acting
force pump such as a simple Lift Pump or a hand-operated Bilge Pump. |
stroke of the piston fills one chamber and empties another, which nearly doubles
the flow rate (less the volume of the piston rod) over a single-acting force pump.
It also smooths the flow.
From the outside this pump can take many forms,
but the basic principal of operation will be identical.
