5.4.2 HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate,
sealing between pipe joints is adequate for the process fluids and proper
process and pressure protection devices are in place. It is also the
responsibility of the installer to assure that process gasses are not vented
in a manner that would be hazardous. Refer to the manufacturer of the
process media to assure that proper safety precautions are in place.
5.4.3 COOLING WATER
The cylinder cooling water jacket is shipped dry. Fill the water jacket before starting the pump.
If an optional water flow modulating valve (Water Miser) is fitted, the cylinder may take 20 minutes or more
to fill. The delay can be avoided by lifting the spring to open the valve. For installation of the valve see
Figure 6.
Failure to ensure that the cooling water jacket is filled before starting the pump will result in localized over-
heating of the pump and cause extensive damage.
For installations requiring starting at ambient temperatures lower than 60°F (16°C), electric heaters should
be installed in the water jacket with an optional temperature switch installed in the separator housing. (see
Figure 5)
WARNING
Do not allow the cooling water to freeze in the pump.
Freezing of the cooling water jacket usually results in extensive damage to the pump cylinder which cannot
be repaired.
Connect a water supply line with “on-off” valve to the water inlet, and an open drain to the water outlet. The
inlet line should have a flow regulating valve. If the water supply is unreliable, it is advisable to install a flow
switch to stop the pump or signal when the flow is interrupted. Normally the cooling water will be off when
the pump is not running.
