SKF LINCOLN P653S Installation And Maintenance Manual page 7

General Description
The P653S pump is designed for single line
(S) parallel Centro–Matic type lubrication
systems . The pumps integrated design
includes all necessary components to
support Centro–Matic lubrication systems:
• controller to program and monitor lubri-
cation cycle .
• internal pressure transducer .
• internal vent valve .
• three pumping elements connected
together .
• external pressure relief valve .
• reservoir low–level control .
• contacts for remote monitoring .
• 120/230 V AC power supply .Pump can
supply adequate lubricant to bearings us-
ing oil injectors SL–32, SL–33 SL–41,
SL–42, SL–43 and SL–44 . Number of in-
jectors should be based on output of the
pump being 1 .8 in /min . (30 ml/min.)
3
Pump for 120/230 V AC power supply can be
installed in any stationary industrial type of
applications requiring lubrication for the
same number of medium size bearings .
!
Notice
Installations using SL–32 and
SL–33 Lincoln injectors can lubricate
more than 35 bearings .
Typical Centro–Matic system schematic
is shown on page 31.
!
Notice
Use only supply line hose and
fittings that are appropriate for the
programmed/set system pressure .
