sswm.infoobtain a cost analysis of variable speed versus constant speed for the specific application. Normally the addition of one or more smaller modulating pumps in parallel with the other pumps will be selected to handle any demand for varying pumping rates. 3.2.2 MOTORS. Motors will be selected with sufficient capacity to drive the pumps

www.parker.comlength of stroke of the pumping pistons. This length of stroke, in turn, is determined by the position of the swash plate. Maximum flow is achieved at an angle of 15-17 degrees. The rotating barrel, driven by the prime mover, moves the pistons in a circular path and the piston slippers are supported hydrostatically against the face of the swash ...
Building a farm dam - Department of Primary Industries
www.dpi.nsw.gov.auUnless your dam fills from a spring or by pumping from a river or bore, the source of water will be rainfall that runs off the catchment. The catchment is the area that collects rainfall run-off and directs it to the dam. The catchment can be natural, like fields and forest, or it can be artificial, like roads and roofs.
