DO NOT attempt any maintenance or disassembly of the pump or pump unit
without first ensuring that :
-
The pump is fully isolated from the power source (electric, hydraulic,
pneumatic).
- The pumping chamber, pneumatic relief valve and any shaft seal
support system are depressurized and purged.
- Any temperature control devices (jackets, heat-tracing, etc) are fully
isolated, that they are depressurized and purged, and components are
allowed to reach a safe handling temperature.
DO
NOT attempt to dismantle a pressure relief valve which has not
had the spring pressure relieved, is still connected to a pressurized
gas/air supply or is mounted on a pump that is operating. Serious
personal injury or death and/or pump damage may occur.
DO NOT loosen or undo the front cover, any connections to the pump, shaft
seal housings, temperature control devices, or other components, until sure
that such action will not allow the unsafe escape of any pressurized media.
Pumps and/or drives can produce sound power levels exceeding 85 dB(A)
under certain operating conditions. When necessary, personal protection
against noise must be taken. Typical noise emission data can be found in
section 5.8.
Avoid any contact with hot parts of pumps and/or drives which may cause
injury. Certain operating conditions, temperature control devices (jackets,
heat-tracing, etc.), bad installation, or poor maintenance can all promote high
temperatures on pumps and/or drives.
When cleaning, either manually or by CIP method, the operator must ensure
that a suitable procedure is used in accordance with the system requirements.
During a CIP cleaning cycle, a pump differential pressure of between 30 and
45 psi is recommended to ensure suitable velocities are reached within the
pump head. The exterior of the pump should be cleaned periodically.
