Flange Connections
The fluid inlet and outlet ports are 1–1/2 in. raised
face, standard 150 lb class pipe flanges. Connect
1–1/2 in. flanged plastic pipe to the pump as follows.
You will need:
D Torque wrench
D Adjustable wrench
D a 5 in. diameter, 1/8 in. thick PTFE gasket, with
four 0.63 in. diameter holes on a 3.88 in. diameter
bolt circle, and a 1.75 in. diameter center
D four 1/2 in. x 3 in. bolts
D four 1/2 in. spring lockwashers
D eight 1/2 in. flat washers
D four 1/2 in. nuts.
1. Place a flat washer (E) on each bolt (C). Refer to
Fig. 3.
2. Align the holes in the gasket (B) and the pipe
flange (A) with the holes in the pump outlet flange
(S).
3. Lubricate the threads of the four bolts. Install the
bolts through the holes and secure with the wash-
ers (E), lockwashers (D), and nuts (F).
4. Hold the nuts with a wrench. Refer to the tighten-
ing sequence in Fig. 3 and torque the bolts to 10 to
15 ft-lb (14 to 20 NSm). Do not over-torque.
