NOTE: Remove and reverse the manifold(s) to
change the orientation of inlet or outlet port(s).
Follow Torque Instructions on page 16.
Aluminum (
VA25A
)
The fluid inlet and outlet manifolds each have
four 1 in. npt(f) or bspt threaded ports (F
IG
. 3,
M, N). Close off the unused ports, using the
supplied plugs.
Plastic (
VA25P, VA25C,
and
VA25F
)
The fluid inlet and outlet manifolds each have a
1 in. raised face ANSI/DIN flange (F
IG
. 4, M, N)
in either a center or end location. Connect 1 in.
standard flanged plastic pipe to the pump.
See F
IG
. 5.
Standard pipe flange kits are available in poly-
propylene (819.6885), stainless steel
(819.6886), and PVDF (819.6887). These kits
include:
•
the pipe flange
•
a PTFE gasket
•
four 1/2 in. bolts, spring lock washers,
flat washers and nuts.
Be sure to lubricate the threads of the bolts
and torque to 10-15 ft-lb (14-20 N•m). Follow
the bolt tightening sequence and do not
over-torque.
Stainless Steel (
VA25S
)
The fluid inlet and outlet manifolds each have
one 1 in. npt (f) or bspt threaded port.
