Annual Technical Meeting, 1995
Abstract The theory of Long Stroke Pumping Units (LSPU) and the associated benefits have been generally accepted throughout industry for many years. Unfortunately there is usually a stigma associated with theory in that it sometimes differs greatly with actual results.

High pressure pumps and pump units
2001In this context high pressure cleaning is defined as the use of pressurised water from 250 to 1200 bar, and is often referred to as ‘Hydrodynamic Cleaning’ in view of the fact that it relies on the kinetic energy of the water for cleaning power, as opposed to the use of hot water or chemical additives.

SPE California Regional Meeting, 1970
The success of the sucker-rod system for pumping oil wells is due, primarily, to the pumping oil wells is due, primarily, to the simplicity of the surface, as well as the subsurface equipment. In the early life of the industry the wells were shallow and could be adequately pumped with beam-type surface equipment. As wells were drilled to greater depths

Indexes of pumps for oil field pumping units
Chemical and Petroleum Engineering, 1994As reported previously, a series of oil field pumping units has been developed with power outputs of 125, 250, 500, and 1000 kW, designed for injecting working fluids in cementing operations in oil and gas wells, hydraulic fracturing of formations, washing out sand plugs, and other production operations.

J & S-Stork Pumps: Sealed Motor Pump Units and Turbine Alternator Units
1986During the 1950s increasing temperatures and pressures in steam-generating plant exposed operating difficulties caused by gland-leakages in circulating pumps. An early solution to this problem was to enclose the pump and electric motor in a single pressure-tight shell, eliminating the need for glands or rotating seals.

Das Unit Pump System (UPS) wird bei Nkw und Grosmotoren eingesetzt. Die Arbeitsweise der Unit Pump (UP) entspricht der des Unit Injectors (UI) fur Nkw. Im Gegensatz zum UI sind bei der UP jedoch Einspritzduse und Injektor raumlich getrennt und uber eine kurze Leitung miteinander verbunden. Das Unit Pump System wird daher auch Pumpe-Leitung-Duse genannt.
