Discharge Head, is the net head obtained at the outlet of a pump. For a centrifugal pump, the discharge pressure depends on the suction or inlet pressure as well, along with the fluid’s density. Thus, for the same flow rate of the fluid, we may have different values of discharge pressure depending on the inlet pressure.
A chopper pump is a centrifugal pump which is equipped with a cutting system to facilitate chopping or maceration of solids that are present in the pumped liquid. The main advantage of this type of pump is that it prevents clogging of the pump itself and of the adjacent piping, as all the solids and stringy materials are macerated by the ...
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
Pump and volute casing. A volute is a curved funnel that increases in area as it approaches the discharge port. [1] The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the ...
Injector, a jet-driven pump; Mechanical or rotary lobe pump requiring mechanical parts to pump water; Solar-powered water pump; Pump driven by air as used by the Amish; Pump driven by air as used in the Australian outback; Manual pumpless or hand pump wells requiring a human operator; The pump replaces the use of a bucket and pulley system to ...
Water pumping stations are differentiated from wastewater pumping stations in that they do not have to be sized to account for high peak flow rates. They have five general categories: [3] Source (such as a well) pump discharging into an elevated tank; Raw water pumping from a river or lake; In-line booster pumping into an elevated tank
A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.
An eccentric rotary vane pump Another eccentric rotary-vane pump design. Note that modern pumps have an area contact between rotor and stator (and not a line contact). 1. pump housing 2. rotor 3. vanes 4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In ...
