5.4.6 Position
In principle the ZLND pumps are installed
horizontally.
5.5 Motor
Before assembly check the direction of rotation of
the motor (indicated by an arrow on the pump
casing). If this is not possible the direction of
rotation of the complete unit can only be checked
only if the pump is filled.
In any event, the operating instructions of the
motor manufacturer must be followed, since the
motor is generally incorporated by STERLING
FLUID SYSTEMS into the pump set.
5.6 Alignment of the set
Place shims under the base plate on both sides of
the foundation bolts, 10 mm from the base plate
edge. Use a spirit level to align the set.
If necessary, place shims between the foundation
bolts to prevent the base plate from sagging. Care
should be taken to minimize distortion of the base
plate during installation. The location of the driver
must not be higher than that of the pump. The
max. deviation from the shaft centre line is
±
0.1
mm.
The foundation bolts should be embedded in
concrete using quick-setting grout.
5.7 Coupling
Install the coupling avoiding hard blows, if
necessary in warm condition. Arrange the pump
and motor on a level base. The shaft ends must
be aligned exactly. The distance between each
half of the N-EUPEX B ( FLENDER ) coupling
must be 2 - 3 mm (see fig.).
If other manufacturer’s couplings are used, follow
the manufacturer’s instructions. After installation
on the foundation and connecting the pipework,
the coupling alignment must be checked and re-
aligned, if necessary. Moreover, after reaching the
operating temperature the alignment of the
coupling must be checked again.
The coupling requires a guard that meets DIN
31001 in order to avoid accidental contact during
operation.
In any event, the operating instructions of the
coupling manufacturer must be followed, since the
coupling is a component incorporated by
Sterling
Fluid Systems .

The following is required a = a1 and b = b1
5.8 Checking before installation
Before installing the pump on the plant, the
following points must be checked:
1. is the electrical current to the drive motor
switched off?
2. are suction and discharge lines emptied and
closed by valves?
3. Is it possible to rotate the pump easily by
hand (for this purpose turn the fan of the
motor or the coupling)?
4. Have the latest internal/plant instructions been
observed?.
