2.8 Heating jacket variant
2.8.1 Technical characteristics
To avoid any liquid solidification in the pump, two heating
jackets are located on each side of the body.
Heating jackets permits the circulation of steam or liquid
up to 250°C and up to 12 bar (maximum pressure).
Jacket connections are :
•
P15 - P25 - P40 - P60 pumps :
3/4" B.S.P.F. tapped
holes.
•
P100 pumps :
1" B.S.P.F. tapped holes.
2.8.2 Connection system
The direction of the heating circuit connection to the jac-
ket depends on the nature of the heating fluid :
• If using steam, the inlet will be on the upper opening and
outlet will be on the lower opening.
• If using liquid, the inlet will be on the lower opening and
outlet will be on the upper opening.
• Draining the product when hot could cause serious
injuries or damage.
2.9 Heat insulation
Take care of keeping outboard bearing holder and bea-
ring outside insulation to ensure sufficient bearing cooling.
Coupling guard
: For any application with a pumped
product temperature above 100°C / 212°F, use a perfo-
rated coupling guard to ensure sufficient bearing cooling.
WARNING
BEFORE DRAINING THE HEATING JAC-
KET, IT IS ESSENTIAL TO MAKE SURE
THAT THE PUMP HEATING CIRCUIT AND
HEATING JACKET ARE NO LONGER
PRESSURIZED.
Hazardous pressure
can cause
personal injury
or property damage.
