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 pumps :
3/4" B.S.P.F. tapped holes.
•
P40 - P60 - P100 pumps :
ISO PN16 DN15 f
4 holes M12 at 90° on Ø 65.
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.
P15 - P25
P40 - P60 - P100
• If using liquid, the inlet will be on the lower opening and
outlet will be on the upper opening.
P15 - P25
P40 - P60 - P100
• Draining the product when hot could cause serious
injuries or damage.
2.9 Heat insulation

ring outside insulation to ensure sufficient bearing cooling.
Coupling guard
