Grinder pump station with fiberglass tank and stainless steel lid installed outside a home Grinder pump station with HDPE tank being installed. The grinder pump “station” consists of the pump, a tank, and an alarm panel. A pump for household use is usually 1 hp, 1.5 hp or 2 hp.
The pump manufacturer, Christian Ølgaard, developed a pump with a special knife system to meet the need for macerating and pumping manure in agricultural applications. Manure with high solids content, containing straw and sawdust, would clog up other types of pumps, causing unstable operation in an environment which required high reliability.
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
Uses of pneumatic pressure switches include: Switch a household well water pump automatically when water is drawn from the pressure tank. Switching off an electrically driven gas compressor when a set pressure is achieved in the reservoir; Switching off a gas compressor, whenever there is no feed in the suction stage. in-cell charge control in ...
A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump.It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.
A duplex steam pump has two sets of steam and water cylinders. They are not physically connected but the steam valves on the first pump are operated by the movement of the second pump's piston rod, and vice versa. The result is that there are no "dead spots" and the pump is always self-starting. [2]
In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
The Wood Screw Pump is a low-lift axial-flow drainage pump designed by A. Baldwin Wood in 1913 to cope with the drainage problems of New Orleans. Wood's extremely efficient pumps replaced less efficient pumps in the city's drainage system, prior to which the city had experienced chronic flooding problems, bringing diseases such as malaria and ...
