4.3.16 Flushed Product Seal
Auxiliary Services.
Every Duralobe
®
pump is provided with four seal flushing connections, two on
each side of the rotorcase, which are tapped 1/8" BSP.
There are two flushing connections for each seal, one for flush 'in', the other
for flush 'out', see fig 33 and the piping for the flush should be arranged to
provide an independent flush to each seal.
Pumps are supplied with blanking plugs in each flushing connection. If the
pump has been converted to a flushed product seal, these plugs can be
removed and the flush connections used to provide the appropriate flush.
