Pulsation Bottle Installation

1. Place primary discharge bottle on its adjustable supports in the lowest position. Ensure both cylinder

and bottle flange sealing surfaces are clean and free of damage prior to installation.

2. Adjust primary discharge bottle supports to raise bottle to within 0.125 inch (3 mm) of cylinder

flange.

3. Lubricate and insert flange bolts to allow feeler gauge access at 0°, 90°, 180° and 270°. Confirm

no bolts are flange-bound and all bolts can be threaded in completely by hand.

4. Tighten flange bolts to 45–50 ft-lbs (61-68 Nm) to achieve metal-to-metal flange contact without

excessive force applied to the nozzles or cylinders.

5. Record preliminary feeler gauge readings at 0°, 90°, 180° and 270° per flange.

6. Place primary suction bottle on cylinders and install bolts as previously described for the discharge

bottle.

7. Verify and record all feeler gauge readings.

8. Minor adjustments to cylinder flange rotation are possible at this time. If this is necessary, crosshead

clearance and piston rod runout must be re-verified.

9. The flange gap measured across the sealing surface must be less than 0.016 inch angular gap

across any bolt circle AND less than 0.020 inch (0.5 mm) gap at any one location on the bolt circle.

10. Loosen bottle-to-cylinder flange bolts and install gaskets. Confirm no bolts are flange-bound and

all bolts can be threaded in completely by hand.

11. Tighten all bolts in the following sequence:

a. Apply 25% of torque in criss-cross sequence. Tighten repeatedly as required for consistent

torque on all bolts.

b. Apply 50% of torque in criss-cross sequence. Tighten repeatedly as required for consistent

torque on all bolts.

c. Apply 75% of torque in criss-cross sequence. Tighten repeatedly as required for consistent

torque on all bolts.

d. Apply final torque to all flange bolts until consistent torque is achieved on all bolts.

12. Loosen primary discharge bottle adjustable supports in preparation for piping fit and startup.
