Installation to Plan 23 involves the cooler of working liquid circulating in the pump gland box and appropriate connectors and piping. The external cooling water circuit is connected to the coil located in the cooler. Recirculation is forced through a pumping ring in the gland box, through the cooler and back to this gland box. This system is used with contaminated or special liquids at high temperatures in order to minimize the thermal load of the cooler through cooling only a small amount of liquid being in circulation.
APPLICATION EXAMPLE
Single cartridge mechanical seal e.g. type BC.
