Installation
placed on the pump.
7
Install pressure gauges in the NPT ports provided in the pump casing to check pump
performance at start up.
8
Check alignment of pipes to pump to avoid strains, which might later cause misalignment.
Unbolt flanges or break union joints. Pipes should not spring away or drop down. After pump
has been in operation for a week or two, completely recheck alignment.
Pump Mounting
It is recommended that the unit be permanently mounted by securing the base plate with
adequately sized anchor bolts to a level concrete floor following recommended industry
standards. A solid foundation will reduce system noise and vibration, and will improve pump
performance. Refer to ANSI/HI standards or a suitable pump handbook for information on
typical pump mounting and foundations. Check coupling alignment after pump and base
assembly is secured to the foundation.

Couple Alignment
The pump must be directly coupled to a gear reducer and /or driver with a flexible coupling.
Both angular and parallel coupling alignment must be maintained between the pump, gear,
motor and so on in accordance with manufacture’s instructions. See
.
1
Parallel alignment: The use of a laser alignment tool or dial indicator is preferred. If a laser
alignment tool or dial indictor is not available, use a straightedge. Turn both shafts by hand,
checking the reading through one complete revolution. Maximum offset should be less than
.005 inch (0.127mm).
2
Angular alignment: Insert a feeler gauge between the coupling halves. Check the spacing at 90
degree increments around the coupling (four check points). Maximum variation should not
exceed 0.005 (0.127mm). Some laser alignment tools will check angular alignment as well.

Replace the coupling guards after setting alignment.
