Watson-Marlow SPS - Manual (Page 9)

MasoSine SPS sinusoidal pumps User Manual 9
The pump contains a rotating rotor,
which can crush or sever fingers and
hands. The pump must be guarded so
that it is not possible for people to hold the
pump by its inlet or delivery ports with the
rotor running. When the rotor is stationary,
the drive must be secured against uninten-
tional start-up. Increased danger exists if
pipes are dismantled or the pump is open.
7.13 Constructional changes to the
machine
Make no changes, attachments or conversions to the machine without the manu-
facturer’s approval. All conversion measures require the written confirmation of
Watson-Marlow MasoSine.
Replace machine parts which are not in perfect condition immediately. Use only orig-
inal spare and wearing parts. Parts not obtained from MasoSine are not guaranteed
to be designed and manufactured in compliance with load and safety requirements.
The warranty is invalid if genuine spare parts from MasoSine are not used.
7.14 Noise
The continuous sound pressure level proceeding from the machine should not
exceed 70 dB(A). Higher sound pressure levels that can cause deafness can arise,
depending upon local conditions. If this occurs, protect the operating personnel with
appropriate protective equipment / protective measures.
7.11 Dangers due to hydraulic energy
Only personnel with special knowledge and experience in hydraulics may work on
hydraulic devices.
Relieve the pressure in the system sections and pressure lines to be opened before
starting repair work.
Replace hydraulic hose lines at appropriate intervals, even if no safety-relevant
defects are detectable.
