The safety data sheets of pumping media and other chemical substances are to be observed!
∙
Be careful when handling the pump because of
- high temperatures
- hot discharging media, sealing media, and gases
- rotating parts
Wear suitable working and protective clothes!
∙
Works on adhesive / drum pumps are only to be carried out with appropriate clothing as protection
from high temperature and possible exposure to hot discharging media, sealing media, and gases.

Safety Instructions for Electrically Heated Adhesive Pumps / Drum Pumps or
Clamping Plates
D
Danger!
∙
All adhesive pumps / drum pumps must be earthed. For this purpose, one of the pump fastening
screws may be used.
∙
Protect the electrical heating against short circuit using an appropriate fuse.
∙
Connect the electrical heating to power in installed condition only.
∙
Do not operate the electrical heating without temperature sensor and control.
The heating control must ensure that the max. permissible temperature as specified in the pump data
sheet cannot be exceeded.
∙
The temperature sensor includes two PT100 resistors: One must be used for the heating control, the
other PT100 resistor must be connected to an independent additional temperature monitor. If the max.
permissible temperature as per pump data sheet is exceeded, the electrical heating must be switched
off.
∙
Prevent liquids from flowing over the connecting cable of the electrical heating. Lay the cable taking
this condition into consideration.
Regularly check the connection points of the pumped / sealing medium for leakage.
∙
Do not crush or bend the cable.
∙
The pump may only be operated with personal protection insulation under temperature.
