Plan 21

• PLAN 21 can be used for single  seals alone or combined with PLAN52/53 for double  seals;

• After the pumped fluid is cooled by the cooler, meet secondary sealing element temperature limits to reduce    coking or polymerizing;

• Improve the lubrication performance of the seal end face;

• Provide enough differential pressure to achieve a good flush flow rate.

• The cooler adopts serpentine coil inside, convection heat transfer, heat exchange area is fully utilized, heat exchange effect is good, TUBE coil system, outer wall polishing Ra≤0.4μm, increase heat exchange efficiency, and is not easy to scale;

• The outlet of the cooler is equipped with universal shock resistant bimetal thermometer, which can adjust the Angle arbitrarily, so that the on-site staff can conveniently monitor the temperature of flush liquid in real time.

• The back bracket adopts the design of hanging ear, which is convenient for on-site installation and disassembly.
