A type of foam concentrate proportioning system in which a pump and appropriate devices feed the concentrate to a metering orifice or controller at the same pressure as that of the water supply.  3, fiche 1, Anglais, - balanced%2Dpressure%20proportioner

Balanced pressure proportioner : The use of a separate pump for transporting and pressurizing foam concentrate to be delivered in the correct proportions to a flowing water stream offers the greatest advantage for reliable and accurate operation of a foam concentrate proportioning system which must function at varying rates of volume or pressure during its use.... The balanced pressure system... relies on :(1) a hydraulically monitored pressure control valve in a bypass foam concentrate line from a pump, and(2) a correctly sized venturi-type proportioning controller in the water line for correct and automatic proportioning over wide ranges of flow.  4, fiche 1, Anglais, - balanced%2Dpressure%20proportioner

Balanced-pressure proportioners and around-the-pump proportioners are both systems that are built into the apparatus fire pump. Apparatus equipped with a balanced-pressure proportioner have a foam concentration line connected to each discharge outlets. This line is supplied by a foam concentrate pump separate from the main fire pump. The foam concentrate pumps draws the concentrate from a fixed tank on the apparatus. This pump is designed to supply foam concentrate to a desired outlet at the same pressure at which the fire pump is supplyng water to that discharge.  1, fiche 1, Anglais, - balanced%2Dpressure%20proportioner

Metering pumps move precise volumes of liquid in a specified time period to provide accurate flow rates. This class of pumps moves liquids in two stages: the suction stroke and the discharge stroke. During the suction stroke, liquid is pulled into the pump cavity past the inlet check valve. During the discharge stroke, the inlet valve closes; the outlet valve opens, and the liquid is pushed out. Vary the flow either by changing the stroke length or by adjusting the cycle frequency. Described below are a few types of metering pumps [i.e.] bellows pumps, ... diaphragm pumps, ... piston pumps, ... travelling cylinder pumps ...  5, fiche 2, Anglais, - metering%20pump

A type of liquid foam concentrate proportioning device that feeds the concentrate into the water at the output side of the pump rather than through the pump.  4, fiche 3, Anglais, - around%2Dthe%2Dpump%20proportioner

Record number: 3, Textual support number: 1 CONT

Balanced-pressure proportioners and around-the-pump proportioners are both systems that are built into the apparatus fire pump.... The around-the-pump proportioning system consists of a pickup line on the discharge side of the pump back to the intake side of the pump. An in-line eductor is positioned on this pump bypass. These units are rated for a specific flow and should be used at this rate, although they do have some flexibility. For example, a unit designed to flow 500 gpm(2, 000 L/min) at a 6 percent concentration will flow 1, 000 gpm(4, 000 L/min) at a 3 percent rate.  3, fiche 3, Anglais, - around%2Dthe%2Dpump%20proportioner

Around-the-pump proportioner: This type of proportioner also operates on the venturi principle [as does the "in-line inductor"], except that it must be situated at the pump and connected to both suction and pressure sides. Its advantage is that pressure recovery of the venturi action is attained, and pump delivery pressures to the foam-making device or devices downstream require no compensation for pressure loss except for that in the layout hose length. ... A small portion of the pump discharge flows through a bypass line to the suction side of the pump. A venturi eductor in this line produces a negative pressure on the foam concentrate pickup line from the foam concentrate container. Foam concentrate is led to the eductor where it mixes with water and is delivered to the suction side of the pump.  5, fiche 3, Anglais, - around%2Dthe%2Dpump%20proportioner
