SAFETY INSTRUCTIONS
WARNING:
Pumps must be accessible at all times for operation and
service. Accesses may not be closed off or blocked!
WARNING:
If hazardous or unknown metering media are used, always
first empty out the liquid end and rinse it out for maintenance
and repair work! Observe the safety data sheets of the
metering fluids!
WARNING:
When metering dangerous or unknown fluids, protective
clothing must be worn when working on the liquid end
(glasses, gloves)!
WARNING:
When operating the metering pump against a closed shut-
off element on the delivery side, the resulting pressure
build-up can reach a multiple of the maximum permissible
backpressure!
This can cause the delivery line to burst!
To avoid this, it is advisable to install a ProMinent
multifunction valve which limits the maximum pressure
which can be reached!
WARNING:
The maximum operating pressure for PTFE lines N 1/8"
plug-in system on pipe nipple for gamma/4b SK pumps is
6 bar!
WARNING:
Applicable national and international regulations (ExVo,
VbF, DIN VDE 0165) must be observed when metering
combustible media!
ATTENTION
Only set the stroke length when the pump is running when the
setting bolt of the metering stroke is briefly relieved!
PLEASE NOTE:
Only use the gripper rings and hose nozzles specified for the
respective hose diameter as well as original hoses with specified
hose dimensions and wall thickness as otherwise the stability
of the connection is not guaranteed!
Avoid reducing the hose sizes!
For long lines and highly viscous media the next highest line
diameter or a pulsation dampener should be used!
