6. Maintenance
6.1 Safety informaon
WARNING:
Allow the pump to cool (so that it is at a safe temperature for skin contact) before
starng maintenance work. Make sure the pump is switched o in case the thermal
overload device restarts the pump.
WARNING:
Obey the safety instrucons given below and take note of appropriate precauons.
Failure to do so can cause injury to people and damage to equipment.
▪
If the pump is PFPE-prepared, refer to
PFPE-prepared RV pumps on page 56 before
maintaining the pump.
▪ A suitably trained and supervised technician must maintain the pump. Obey local
and naonal safety requirements.
▪
Ensure that the maintenance technician is familiar with the safety procedures
which relate to the pump-oil and the products processed by the pumping system.
▪ Check that all the required parts are available and of the correct type before
starng work.
▪
Isolate the pump and other components from the electrical supply so that they
cannot be operated accidentally.
▪ Do not reuse O-rings and seals if they are damaged.
▪ Aer maintenance is completed, recheck the direcon of pump rotaon if the
electrical supply has been disconnected.
▪
The pump and the pump-oil will be contaminated with the process chemicals that
have been pumped during operaon. Ensure that the pump is decontaminated
before maintenance and that adequate precauons are taken to protect people
from the eects of dangerous substances if contaminaon has occurred.
▪
Do not touch or inhale the thermal breakdown products of uorinated materials
which may be present if the pump has been heated to 310 °C and above.
Fluorinated materials are safe in normal use but can decompose into very
dangerous substances (which may include hydrouoric acid) if they are heated to
310 °C and above. The pump may have overheated if it was misused, if it
malfunconed, or if it was in a re. Material Safety Data Sheets for uorinated
materials used in the pump are available on request: contact us or the supplier.
▪
If necessary, maintain the motor as specied in the manufacturer's informaon
supplied with the motor.
