4.5.4 Auxiliary piping
4.5.4.1 Pumps fitted with a sole plate packed gland
Ensure lubrication is supplied to the
gland packing.
4.5.4.2 Pumps fitted with mechanical seals
Seal housings/covers having an auxiliary quench
connection require connection to a suitable source of
liquid flow, low pressure steam or static pressure from
a header tank. Recommended pressure is 0.35 bar
(5 psi) or less.
Double seals require a barrier liquid between the
seals, compatible with the pumped liquid.
With back-to-back double seals, the barrier liquid should
be at a minimum pressure of 1 bar (15 psi) above the
maximum pressure on the pump side of the inner seal.
The barrier liquid pressure must not exceed limitations
of the seal on the atmospheric side.
For toxic service the barrier liquid supply and
discharge must be handled safely and in line with
local legislation.
Special seals may require modification to auxiliary
piping described above. Seal on pumps in potentially
explosive atmospheres shall comply with section
1.6.4.3.
Consult Flowserve if unsure of correct
method or arrangement.
4.5.4.3 Pumps fitted with heating jacket
As the pump is constructed as a heated jacketed unit,
steam must be connected to the steam inlet flange and
removed via the steam outlet flange. These flanges
are located on the upper side of the sole plate. A
flanged steam valve should be provided at the steam
inlet and outlet for control of the steam supply.
4.5.5 Final checks
Check the tightness of all bolts in the suction and
discharge pipework. Check also the tightness of all
foundation bolts.
After connecting piping to the pump, rotate the shaft
several times by hand to ensure there is no binding
and all parts are free.
Recheck the flexible element coupling is aligned with
the permitted limits.
Where there is the option of an additional
rigid coupling below the thrust bearing, above the
mechanical seal: this has full metal-to-metal joints
which do not permit its adjustment.
For couplings with narrow flanges use a dial indicator
as shown. The alignment values are maximums for
continuous service.
