WARNING!!!
The importance of correct alignment cannot be overemphasized. The following procedure should be used for
initial installation.
1. Mount pump assembly on steel base, concrete pad or floor and tighten bolts evenly, but not too tight..
2. At this point check alignment of the coupling. This should not be more than that recommended by the
coupling manufacturer.
3. If misalignment is evident, determine which direction the coupling needs to be moved.
4. Loosen all nuts and add the shims underneath the driver to obtain final alignment.
Alignment should be checked and corrected as required after:
- Mounting
- Piping is connected
-
Pump or driver is moved for any reason
3-4 Wiring and Controls:
The electric motor power supply connections must conform to national and local codes. The motor ratings
stamped on the motor nameplate must match the line voltage and wire capacity
.
DO NOT USE ANY OTHER
VOLTAGE.
SECTION IV
OPERATION
CAUTION:
Do not exceed the rated working pressure of the pump.
The sum of the suction pressure and the maximum pump operating head (converted to units of
pressure) must be less than the pump working pressure, at all times.
CAUTION:
Do not exceed the pressure capabilities of the mechanical seals.
The pressure on the mechanical seals for this pump type is equal to the suction pressure.
The suction pressure must not exceed the rated working pressure of the mechanical seals.
4-1 Starting:

Turn the pump shaft by hand to insure that the parts do not bind

Open the valve in the pump suction line, if fitted

Close discharge valve
