Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They operate by the conversion of pressure energy into velocity in suitable nozzles. They are “pumps without moving parts”. The basic principle of jet pumps consists in the liquid or gas jet being emitted by a nozzle at high speed entraining and accelerating the surrounding liquid, gas or solid matter. The result of this action is a mixture of the driving and entrained (sucked) fluids, the velocity of...

The scope of delivery of the jet pumps department of GEA Wiegand is divided into two main fields. 1) DELIVERY OF STANDARD APPARATUSES This catalog gives a wide selection. The types and sizes are selected such that for usual tasks a suitable unit can always be found. Description and capacity curves and the corresponding sheets allow the correct choice. 2) DESIGN, CONSTRUCTION AND DELIVERY OF SPECIAL APPARATUSES AND PLANTS For this purpose our well-trained staff of specialists in jet pumps and vacuum systems is available. In our modern Research Laboratory, the required analyses, research work and...

The units for measurement and weight are in accordance with the International System of Units (SI) recommended by the International Organisation of Standardisation (ISO). For the technical range which is the subject matter of this catalog, the following basic units of measurement and the corresponding abbreviations, taken from the International System of Units, shall apply. THE MOST IMPORTANT OF THE DERIVED UNITS ARE: The table Conversion from technical system of units to international system of units shows a comparison between the earlier used Technical System of Units and the newly, legally...

The following tables show the units of measurement for pressure, energy and capacity in use ever since in comparison to the units of the international system of units (SI). PRESSURE UNITS ENERGY UNITS CAPACITY UNITS PRESSURE, DEFINITION OF TERMS AND UNITS In technology, various units of pressure are used. A differentiation is made between absolute pressure, differential pressure and gauge pressure. absolute pressure pabs. takes as its basis zero pressure of a pure vacuum. differential pressure Ap is the difference between two pressures. gauge pressure pe is the difference between an absolute...

The temperature values to be converted are given in the coloured centre column. The corresponding values in °C are given left of the centre column, the values in °F are given right of the centre column. EXAMPLES: 1. Value to be converted (centre column) 20 °C = + 68 °F (right column) 2. Value to be converted (centre column) 20 °F = - 6.6 °C (left column) CONVERSION EQUATION: abl3 18 14 wa Jft engineering for m a better world Am Hardtwald 1, 76275 Ettlingen, Germany chemical©gea.com, gea.com

If mixtures of vapors and gases are condensed under vacuum, the gases and certain portions of non-condensed vapors will have to be drawn off by means of a vacuum pump in order to maintain the required vacuum in the condenser. The drawn-off gases (e.g. air) are saturated with the vapors of the partly condensed components. In the following it is assumed that these components are insoluble in each other in the liquid phase. Condensation of a component of such a gas-vapor mixture will take place if this component is brought to a saturated steam condition (dew point) by cooling the mixture. A saturated...
