The parts are meant for lowering the temperature of lubricating and cooling
(sealing or barrier) liquid to the degree, which provides the correct work of
double-stage (plan 52 standard API 682) and double (plan 53) face seals, applied
in centrifugal pumps. The parts allow to carry out the local and remote control
of seal state and to protect the pump in the case of breakdown.

Design features:
1. The equipment is interchangeable with known cooling vessels of both home
and foreign manufacture.
2. Material of composite parts is corrosion-resistant steel; material of
gaskets is thermal expanded graphite.
3. Design of the heat exchanger allows of cleaning the cooler tubes in the
place of the unit installation as far as the tubes become locked by mechanical
particles, such as scale, incrustations or plugs.
4. It is unnecessary to pour the sealing liquid out of the heat exchanger
before maintenance.
5. The heat exchanger has several outside ball connections for attaching
supply and discharge pipelines.
6. The cooling system has the following design:
6.1. According to the mutual alignment of the heat exchanger and face seal
on the pump:
- Right position (basic);
- Left position (mirror).
6.2. According to the complete set of Electrical Control and Instrumentation
