frame. The outboard bearing is shouldered and
locked to the shaft and housing to enable it to
carry radial and thrust loads. All fits are
precision machined to industry standards. The
inboard bearing is a single row deep groove
ball bearing. The outboard bearing is a double
row angular contact bearing, except for the LTX
which uses a pair of single row angular contact
ball bearings mounted back-to-back.
Power End - The oil level is viewed through a
sight glass. Optional oil cooling is provided by
a finned tube cooler. A finned tube cooler is
standard with HT 3196. Flood oil lubrication is
standard. The power end is sealed with
non-metallic labyrinth seals. No machining is
requried to convert from oil to grease or oil mist
lubrication. Regresable bearings and oil mist
lubrication are optional.

supplied by contacting your local Goulds sales
representative.
HANDLING
s
!WARNING
Pump and components are heavy. Failure to
properly lift and support equipment could result in
serious physical injury or damage to pumps. Steel
toed shoes must be worn at all times.
Use care when moving pumps. Lifting equipment
must be able to adequately support the entire
assembly. Hoist bare pump using a suitable sling,
under the suction flange and bearing frame. Base-
plate mounted units are moved with slings under the
pump casing and driver. Refer to Figs. 4-7 for
examples of proper lifting techniques.

Equipment that is to be installed in a potentially explosive environment must be done so in
accordance with the following installation instructions.
BASEPLATE INSPECTION
1. Remove all equipment.
2. Completely clean the underside of baseplate. It is
sometimes necessary to coat the underside of the
baseplate with an epoxy primer. This may have
been purchased as an option.
3. Remove the rust preventative solution from the
machined pads with an appropriate solution.
SITE / FOUNDATION
A pump should be located near the supply of liquid
and have adequate space for operation, maintenance,
and inspection.
Baseplate mounted pumps are normally grouted on a
concrete foundation, which has been poured on a
solid footing.
The foundation must be able to absorb any vibration
and to form a permanent, rigid support for the
pumping unit. The location and size of the foundation
bolt holes are shown on the outline assembly
drawing, provided with the pump data package.
ANSIFAM IOM - 12/03 19
33

All equipment being installed must be
properly grounded to prevent unexpected
static electric discharge. This includes
ensuring that the PFA lined pumps (Model
3198) and the non-metallic liquid end pumps
(Model NM3196) are pumping fluids that are
conductive. If not, a static electric
discharge may occur when the pump is
drained and disassembled for maintenance
purposes.
Foundation bolts commonly used are sleeve type
(Fig. 8) and J type (Fig. 9). Both designs permit
movement for final bolt adjustment.
1. Inspect foundation for dust, dirt, oil, chips, water,
etc. and remove any contaminants. Do not use
oil-based cleaners as grout will not bond to it.
2. Prepare the foundation in accordance with the
grout manufacturer’s recommendations.
LEVEL BASEPLATE
CAST IRON/PERMABASE™/FAB. STEEL
1. Place two sets of wedges or shims on the
foundation, one set on each side of every
foundation bolt. The wedges should extend .75 in.
(20mm) to 1.50 in. (40mm) above foundation, to
allow for adequate grouting. This will provide
even support for the baseplate once it is grouted.
2. Remove water and/or debris from anchor bolt
holes/sleeves prior to grouting. If the sleeve type
bolts are being used, fill the sleeves with packing
or rags to prevent grout from entering.
3. Carefully lower baseplate onto foundation bolts.
4. Level baseplate to within .125 in. (3.2mm) over length
of the baseplate and to within .088 in. (1.5mm) over
the width of the base by adjusting wedges.
5. A level should be placed across the pump
mounting pads and the motor mounting pads.
6. Hand tighten the bolts.
