The Kinzua Dam in Pennsylvania, with outlet works releasing water. A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very ...
The traditional hot water recirculation system uses the existing cold water line as return line from the point of use located farthest from the hot water tank back to the hot water tank. The first of two system types has a pump mounted at the hot water heater while a "normally open" thermostatic control valve gets installed at the farthest ...
A minimum flow protection system ensures that the pump is not operated below the minimum flow rate. The system protects the pump even if it is shut-in or dead-headed, that is, if the discharge line is completely closed. [44] The simplest minimum flow system is a pipe running from the pump discharge line back to the suction line.
A water outlet. Each of these plumbing fixtures has one or more water outlets and a drain. In some cases, the drain has a device that can be manipulated to block the drain to fill the basin of the fixture. Each fixture also has a flood rim, or level at which water will begin to overflow. Most fixtures also have an overflow, which is a conduit ...
[2] No inherent redundancy for the pump. A zone-valved system is dependent upon a single circulator pump. If it fails, the system becomes completely inoperable. The system can be harder to design, requiring both "SPDT" thermostats or relays and the ability of the system to withstand the fault condition whereby all zone valves are closed ...
The outer cavity serves as the inlet, while the inner (partial) tube serves as the outlet. A coiled plastic tube will suffice for this arrangement. The outlet pipe is fixed to a water wheel, engine or animal which is capable of rotating the pump quickly. Due to this rotation, water is picked up by the outer cavity and pumped upwards in the hose.

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.
