There are three different types of foam proportioners commonly used in the fire service: line eductors, balanced pressure proportioners, and around-the-pump proportioners. The line eductor is the simplest and least expensive proportioning device. It has no moving parts in the water way, which makes it durable and dependable. The line eductor may be attached to the hoseline or may be part of the nozzle. There are two different types of line eductors: the in-line eductor and the self-educting nozzle. Both types of eductors use the venturi principle to draft foam concentrate into the water stream. As water at high pressure passes over a reduced opening, it creates a low-pressure area near the outlet side of the eductor. This low-pressure area creates a suction effect. The eductor pickup tube is connected to the eductor at this low-pressure point. The pickup tube submerged in the foam concentrate draws concentrate into the water stream, creating a foam water solution.  6, record 1, English, - in%2Dline%20foam%20concentrate%20inducer

Foam Concentrate Proportioners. In order that a predetermined volume of liquid foam concentrate may be taken from its source and placed into a water stream to form a foam solution of fixed concentration, the following two general method classifications are made: 1. Methods which utilize the pressure energy of the water stream by venturi action and orifices to induct concentrate. ... Methods which utilize external pumps or pressure heads to inject concentrate into the water stream at a fixed ratio to flow.  2, record 2, English, - foam%20inductor

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.  3, record 3, English, - eductor%20pickup%20tube

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, record 4, English, - 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, record 4, English, - balanced%2Dpressure%20proportioner

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, record 5, English, - around%2Dthe%2Dpump%20proportioner
