Small compressed air powered breathing gas booster pump Haskell booster set up for charging rebreather cylinders from premix banks with low pressure compressor. A booster pump is a machine which increases the pressure of a fluid. It may be used with liquids or gases, and the construction details vary depending on the fluid.
The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4] From here the cycle starts all over again until the sewage reaches its point of destination—usually a treatment plant. By this method, pumping stations are used to move waste to higher elevations.
The size of the station and the number of compressors (pumps) varies, based on the diameter of the pipe and the volume of gas to be moved. Nevertheless, the basic components of a station are similar. Natural gas may move through a pipeline system typically at speeds of up to 25 mph (11.2 m/s), depending on pressures and pipeline diameters.
When a system includes a centrifugal pump, an important design issue is matching the head loss-flow characteristic with the pump so that it operates at or close to the point of its maximum efficiency. Pump efficiency is an important aspect and pumps should be regularly tested. Thermodynamic pump testing is one method.
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]
Water was filtered in the water injection filters, one duty and one on standby/backwash. From the filters water was routed to the water injection pumps. The three water injection pumps each had a capacity of 221 m 3 /hr with a differential head of 2068.5 metres (209 bar). The pumps discharged to the 3,000 psi manifold and wellheads.
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 jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...
