4 INSTALLATION
Equipment operated in hazardous locations shall
comply with the relevant explosion protection
regulations. See section 1.6.4,
Products used in
potentially explosive atmospheres.
4.1 Location
The pump should be located to allow room for access,
ventilation, maintenance and inspection with ample
headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped.
Refer to the general arrangement drawing for the
pump set.
4.2 Part assemblies
It is the responsibility of the installer to ensure that the
seal system is properly installed to the pump.
4.3 Foundation
There are many methods of installing
pump units to their foundations. The correct method
depends on the size of the pump unit, its location and
noise vibration limitations. Non-compliance with the
provision of correct foundation and installation may
lead to failure of the pump and, as such, would be
outside the terms of the warranty. Ensure the following
requirements are met.
The base plate should be mounted onto a firm
foundation, either an appropriate thickness of quality
concrete or sturdy steel framework. (It should NOT be
distorted or pulled down onto the surface of the
foundation, but should be supported to maintain the
original alignment.) Concrete is the most suitable
material for the base.
The base should contain recesses for the grouting of
the foundation bolts. Figure 3 shows a number of
variations on the design of the foundation bolts.
Make these recesses in the base in accordance
with the above figure, referring to the dimensional
drawing of the pump unit.
If a concrete base is used, observe the following
points:
do not place the pump unit on the base until it
is
completely
set;
fill the recesses with water at least 24 hours
before grouting the foundation bolts. Wetting
the recesses will strengthen the bond between
the mortar of the foundation bolts and the base;
remove the water from the recesses when the
foundation bolts are being grouted;
4.3.1 Positioning the foundation bolts
Lift the pump unit above the base in
accordance with the lifting instructions
described in § 3.1.
Place the foundation bolts with nuts and
washers in the foundation frame.
Take the following points into account when
positioning the pump unit:
The foundation bolts should be suspended
freely in the recesses of the base.
The level of the center line of the suction and
discharge nozzles should correspond with the
center line of the pipes to be connected.
The position of the suction and discharge
nozzles in the y and z directions (see Figure 2)
and
The vertical distance between the base and the
foundation frame (40 mm) before filling with
mortar.
Lay steel filler blocks 25 mm thick on the base
on either side of the foundation bolts.
Place the pump unit on the filler blocks.
Lay thin filler plates under the adjusting bolts.
Adjust the pump unit so that it is roughly level
and at the required height by turning the
adjusting bolts in the welded-on adjusting
bosses of the foundation frame so that the
suction and discharge flange can be mounted
on the pipe flanges without stress. There
should be a parallelism of 0.1 mm between the
flanges to be connected.
