^m%Jf%J FOR CLOSE TEMPERATURE CONTROL BOLT-ON JACKETS are available for Eco Gearchem® pumps to enable the user to maintain close control of pumping temperatures. The jackets are particu- larly useful where fluids tend to thicken or solidify when temperatures decrease, where saturated or supersaturated solutions are prone to precipitation in the event of temperature drop, or where solvents or other liquids with high vapor pressures need to be kept cool to pre- vent vapor locking. The two-piece jackets can be mounted on new pumps or retrofitted to existing Gearchem pumps in the field. They are available in five sizes to fit G2/GA2 and GA16 pumps. Jackets can also be used with threaded GA12 pumps at slightly lower heat transfer efficiencies. Designed to conform closely to the contours of the various pumps, and covering front, rear and center housings, the jackets transfer heat evenly with no hot or cold spots developed. The use of a plastic heat transfer compound to fill any slight voids between the jacket halves and the pump housings is recommended for maximum efficiency and rapid response to temperature changes when so required. EASY MAINTENANCE FEATURED Pumps equipped with jackets are easily accessible for routine maintenance, since the two jacket halves can slide easily over suction and discharge piping. Access to pump bearing flush ports as well as center housing vent ports is maintained in the jacket design. inefficient heat tracing using either elec- trical tape or small, hard-to-bend steam lines, which must be removed — sometimes with difficulty — prior to pump maintenance. Each jacket half consists of an aluminum casting poured around a central steel reservoir through which the heating or cooling medium circu- lates. Connections to the reservoir are brought to the outside using stan- dard steel pipe couplings. A braided, flexible, metallic hose connects the The jackets are hydrostatically tested to 225 psig and the heating medium may be steam at pressures to 150 psig, or any of the organic heat transfer fluids such as Dowtherm®, Arochlor®, Theminol®, Mobiltherm®, etc. Coolants such as Fluorocarbons, glycols, methanols or brine solutions may also IMPORTANT COST SAVINGS Because of the relative small size of ECO Gearchem pump housings, it is impractical to cast jackets integrally with the housings. However, even if this were not the case, replacement costs for housings of 316 stainless steel, alloy 20 or high-nickel alloy C due to corrosion or wear would be very expen- sive. The bolt-on jackets can be re-used, or even moved from pump to pump as requirements change. TYPICAL APPLICATIONS Jackets are recommended in outdoor applications for caustics, heavy acids, fatty glycerols, alum, polyols, resins, coal tar derivatives and similar prod- ucts. They also are useful when han- dling adhesives, plasticizers, waxes, hot soap solutions, bottoms in distilla- tion systems and wiped film evapora- tors, and other situations where fluids must be kept at elevated temperatures. When handling low boilers, pump jack- ets with a cooling medium can often solve a vapor lock problem without the need to change the driver to give a lower pump operating speed.
