A spiral pump, sometimes called a Wirz pump or incorrectly Wirtz pump, is a low lift pump which is composed of a long piece of metal plating, which is wound into a coil and sealed at the top and back extremities so as to resemble a cylinder. The outer cavity serves as the inlet, while the inner (partial) tube serves as the outlet.
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 ...
A chain pump is a type of water pump that uses a chain to move water from one place to another. It works on the principle of a continuous loop of chain moving through a series of sprockets, with attached buckets that lift water as the chain passes over the top sprocket and discharge it as the chain reaches the bottom.

Butch, femme, drag, camp, zhuzh and more are now in common parlance, thanks to Polari, as well as some quite spicy terms, like cherry, dish and more (but more on that later).
By installing a thermostatically controlled pump just after the farthest fixture on the loop, cyclic pumping maintains ready hot water up to the last fixture on the loop instead of wasting energy heating the piping from the last fixture to the water heater. Installing a circulation pump at the farthest fixture on a hot water circulation loop is ...
Durability needs to be incorporated into pump design to the handle the heavy use (and abuse). The India Mark II is a human-powered pump designed to lift water from a depth of 50–80 m. [1] The Mark II is world's most widely used water handpump. [2] The pump was designed in the 1970s to serve village water needs in developing countries and ...
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
The PlayPump water system is a playground merry-go-round attached to a water pump. The spinning motion pumps underground water into a 2,500-liter tank raised seven meters above ground. The water in the tank is easily dispensed by a tap valve. According to the manufacturer the pump can raise up to 1400 liters of water per hour from a depth of 40 ...
