An o-ring boss seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an o-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system differs from others in that a nut is tightened over an o-ring in a chamfered area, creating a fluid-tight ...
Typical Marman Clamp System. A Marman clamp is a type of heavy-duty band clamp; it allows two cylindrical objects to be clamped together end-to-end with a ring clamp. It is sometimes also known as a "Marman ring". It consists of a circular strap with an interior V-shaped groove.
Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
this pumping system is suitable only if the head is relatively low. If one wants to obtain a high head, one has to choose a conventional pumping system. because of the principle, air (oxygen) dissolves in the liquid. In certain cases, this can be problematic, as, for example, in a waste water treatment plant, before an anaerobic basin.
A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

Electrical pumps had been used in the secondary propulsion system of the Agena upper stage vehicle. [ 1 ] As of December 2020, the only rocket engines to use electric propellant pump systems are the Rutherford engine, [ 2 ] ten of which power the Electron rocket, [ 2 ] and the Delphin engine, five of which power the first stage of Astra Space ...
The O-ring theory of economic development is a model of economic development put forward by Michael Kremer in 1993, [1] which proposes that tasks of production must be executed proficiently together in order for any of them to be of high value. The key feature of this model is positive assortative matching, whereby people with similar skill ...
The basic working principle of an air-operated double diaphragm pump. Cross-section sketch of diaphragm fuel pump Air-operated double diaphragm pump. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve ...
