PUMP DESCRIPTION
The Model TSMP is a high pressure, multi-stage, between
the bearings, horizontal centrifugal pump designed to meet
the rigorous demands of the petroleum and petrochemical
market place. It is in full compliance with API 610 10th
Edition (ISO 13709).
Casing -The casing is mounted with side suction and side
discharge nozzles. ANSI class 900+ (Higher flange options
available) pound raised face serrated flanges with a
125-250 rims finish are standard. 600 and 1500 pound and
ring type joint (RTJ) flanges are available options.
Impeller -The impeller is a fully closed design and is
keyed.
Seal Chamber -The Model TSMP has a seal chamber
designed in accordance with API 682 2nd Edition criteria.
Customer selected cartridge mechanical seals are standard.
Bearing Housings -Ductile iron bearing housings are
standard on non-API services and carbon steel on API
services. Oil level is viewed through a sight glass. Constant
level oilers and labyrinth seals are standard. No machining
is required to convert the standard ring oil lube to either
purge or pure mist, although pure mist applications require
minor bearing housing modifications. Pressure lubrication is
required with hydrodynamic thrust bearings.
Shaft -The heavy duty shaft is designed for cartridge
mechanical seals, minimal shaft deflection at the seal faces
(.002) when run in the worst case condition (typically
minimum flow), and a critical speed at least 20% above
design operating speed. Fully compliant with API 10th
Edition (ISO 13709).
Bearings -Radial loads are carried by a single row, deep
groove ball bearing (standard) or sleeve bearings
(optional). The axial thrust load is handled by a pair of
single row angular contact ball bearings mounted back to
back (standard), or a hydrodynamic thrust bearing (used
with sleeve type journal bearings). When ball bearings are
used (standard), the outboard bearing (thrust bearing) is
shouldered and locked into place, thus enabling it to carry
both radial and axial thrust loads. All fits are precision
machined to both the shaft and bearing housing to industry
standards. Size 6x8-13 pumps come standard with
sleeve/ball bearing arrangement.
Baseplate -The fabricated steel baseplate is designed to
support the pump, driver and accessories in accordance
with API 10th Edition (ISO 13709) requirements.
Direction of Rotation -Counterclockwise (left hand) as
viewed from the driver, looking at the pump shaft. (Check
with the factory for clockwise rotation.)

GENERAL INFORMATION
Procedures for installation described in this section are
general. More detailed procedures are described in various
publications including API Recommended Practice
686/PIP (Process Industry Practices) REIE 686,
"Recommended Practices for Machinery Installation and
Installation Design." A pump should be located near the
liquid supply and have adequate space for operation,
maintenance, and inspection. Be sure to allow for crane or
hoist service.
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.
All equipment being installed must be properly
g
rounded to prevent unexpected static electric
discharge.
The location and size of foundation bolts are shown on the
outline assembly drawing provided with the pump data
package.
Foundation bolts commonly used are sleeve type (Fig. 7)
and J type. If using the sleeve type, the inside diameter of
the sleeve should be 2 1/2 -3 times the bolt diameter. A
washer should be placed between the bolt and the sleeve.
Both foundation bolt types permit movement for final bolt
adjustment.

BASEPLATE INSTALLATION PROCEDURE
Industry standard procedures, such as API RP 686/ PIP
REIE 686, and/or the following procedure should be
followed prior to grouting the baseplate. The procedure
assumes the installer has a basic knowledge of baseplate
and foundation design and installation methods.
BASEPLATE PREPARATION
1-Inspect all surfaces of baseplate that will contact grout for
contamination (e.g. -rust, oil, grime, etc.).
1- Thoroughly clean all surfaces of the baseplate that will
contact grout with a cleaner that will not leave any residue.

Remove water and/or debris from foundation bolt
holes/sleeves. If the sleeve type bolts are being
used, fill the sleeves with nonbinding moldable
material and seal to prevent grout from entering.
Coat exposed portion of anchor bolts with a
non-bonding compound (such as paste wax) to
prevent grout from adhering to anchor bolts.
2-Inspect all machined surfaces for burrs, rust, paint or
any other type of contamination. If necessary, use a
honing stone to remove burrs.
Chip top of foundation a minimum of 25 mm) to
remove porous or low strength concrete. If using a
pneumatic hammer, assure that it is not contaminating
the surface with oil, moisture, etc

If recommended by grout manufacturer,
coat foundation surface with a
compatible primer.
3-Coat portions of leveling screws that will contact grout
with a non-bonding (anti-seize) compound (such as paste
wax) to facilitate their removal after grouting.
4-Thread nuts on foundation bolts and hand tighten.
FOUNDATION PREPARATION
SETTING AND LEVELING BASEPLATE

Lower base onto foundation bolts. Base will rest
on top of foundation on jackscrews provided on
base (Figs. 9 & 10).
Adjust leveling jack screws, located adjacent to
the foundation bolt holes, until the baseplate rests
1-2 in. (25 -50 mm) above foundation to allow for
adequate grouting. This will provide even support
for the base once it is grouted.
Level base to within .002 in./ft. (0.20 mm/m) of
length or width of the base, respectively, by
adjusting leveling screws. Maximum total
variation from one end or side of the base to the
other is .015 in. (0.38 mm).
�CAUTION
Do not use heavy tools such as jackhammers, as they
could damage the structural integrity of the
foundation.
