Booster pumps for household water pressure are usually simple electrically driven centrifugal pumps with a non-return valve. They may be constant speed pumps which switch on when pressure drops below the low pressure set-point and switch off when pressure reaches the high set-point, or variable speed pumps which are controlled to maintain a ...
Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]
The storage cylinders may be used independently in sequence using a portable transfer whip with a pressure gauge and manual bleed valve, to transfill the receiving cylinder until the appropriate fill pressure has been reached, or the storage cylinders may be connected to a manifold system and a filling control panel with one or more filling whips.
A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head " (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate.
Despite Anderson leaving the company, the trucks kept the Hayes-Anderson badging until 1934. In 1935, Hayes added diesel engines to their trucks; the first logging truck manufacturing company to do so. Throughout the late 1930s, Hayes was a distributor of British-made Leyland trucks, and the Leyland trucks supplemented Hayes' range of trucks ...
Feedwater pumps range in size up to many kilowatts and the electric motor is usually separated from the pump body by some form of mechanical coupling. Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam ...
A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
