4 Installation
4.1 Installation
4.1.1 Foundation
The foundation should be sufficiently substantial to absorb any vibration, and to form a permanent rigid
support for the pump. A concrete foundation, with foundation bolts of the proper size grouted in place to
drawing dimensions, is recommended.
4.1.2 Mount the pump
1. On the foundation surface, position the baseplates under the frame at the foundation bolts.
The baseplates support the pump.
2. Set the baseplates in a puddle of grout, and level them in all directions and in relation to each other.
This ensures a minimum amount of shimming necessary in order to completely level the pump.
3. Tighten the foundation bolts evenly.
4. Check that the pump is level.
5. Tighten the foundation bolts evenly and recheck pump levelness.
4.1.3 Piping
NOTICE:
The piping should not be connected to pump until unit has been set per instructions and grout-
ed in.
1. Support piping close to, but independently of pump.
2. Keep piping as straight as possible, with few or no bends and fittings.
3. Remove burrs, sharp edges, ream pipe cuts, and make joints air tight.
4. Do not "spring" pipes to make connection. Strain must not be transmitted to pump.
4.1.4 Suction pipe
1. The suction pipe should be as short as possible, containing a minimum number of fittings. It
should be so arranged that one section may be readily removed to allow the dismantling of the
suction half casing. Victaulic or similar type couplings are recommended for this section of the
pipe to facilitate dismantling. The suction pipe should slope upwards to the pump nozzle.
2. Suction line inlet in the sump must be flooded at all times, even if it necessary to install the
pumps so that a suction lift is involved. The pump must never be throttled by the use of a valve
on the suction side of the pump. It is advisable to have a shut-off valve in the suction line so that
the pump can be isolated while repairs are being made, but this valve should never be used to
control the capacity of the pump by throttling.
4.1.5 Discharge pipe
On long horizontal runs, it is desirable to maintain as even a grade as feasible. Avoid high spots, such as
loops, which will collect air and throttle the system or lead to erratic pumping or surging.

5 Commissioning, Startup, Operation, and
Shutdown
5.1 Preparation for startup
WARNING:
•Risk of serious physical injury or death. Exceeding any of the pump operating limits (e.g. -
pressure, temperature, power, etc.) could result in equipment failure, such as explosion,
seizure, or breach of containment. Assure that the system operating conditions are within
the capabilities of the pump.
• Risk of death or serious injury. Leaking fluid can cause fire and/or burns. Ensure all open-
ings are sealed prior to filling the pump.
• Breach of containment can cause fire, burns, and other serious injury. Failure to follow
these precautions before starting the unit may lead to dangerous operating conditions,
equipment failure, and breach of containment.
• Risk of explosion and serious physical injury. Do not operate pump with blocked system
piping or with suction or discharge valves closed. This can result in rapid heating and va-
porization of pumpage.
• Risk of breach of containment and equipment damage. Ensure the pump operates only
between minimum and maximum rated flows. Operation outside of these limits can cause
high vibration, mechanical seal and/or shaft failure, and/or loss of prime.
WARNING:
•Risk of death, serious personal injury, and property damage. Heat and pressure buildup
can cause explosion, rupture, and discharge of pumpage. Never operate the pump with
suction and/or discharge valves closed.
• Running a pump without safety devices exposes operators to risk of serious personal in-
jury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed.
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
Precautions
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified.
5 Commissioning, Startup, Operation, and Shutdown
Model SRL, SRL-C, and SRL-XT Installation, Operation, and Maintenance Manual 15

CAUTION:
When a cartridge mechanical seal is used, ensure that the set screws in the seal locking ring
are tightened and that the centering clips have been removed prior to startup. This prevents
seal or shaft sleeve damage by ensuring that the seal is properly installed and centered on the
sleeve.
NOTICE:
• Verify the driver settings before you start any pump. Refer to the applicable drive equip-
ment IOMs and operating procedures.
NOTICE:
You must follow these precautions before you start the pump:
• Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order
to prevent premature failure at initial startup.
5.2 Check the rotation
WARNING:
•Starting the pump in reverse rotation can result in the contact of metal parts, heat genera-
tion, and breach of containment. Ensure correct driver settings prior to starting any pump.
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
1. Disconnect the coupling from the driver or the belts from the drive. Make sure no parts are loose.
2. Lock out power to the driver.
3. Reinstall the coupling or the belts.
4. Reinstall the coupling or belt drive guard.
5.3 Lubricate the bearings
CAUTION:
Risk of bearings overheating and failing.
• Do not over oil the bearings.
• The maximum operating temperature for ball bearings is 82°C | 180°F.
• If the temperature of the bearing frame exceeds 82°C | 180°F (measured by thermome-
ter), shut down the pump to determine the cause.
• Do not mix oils from different suppliers.
5.2 Check the rotation
16 Model SRL, SRL-C, and SRL-XT Installation, Operation, and Maintenance Manual

All horizontal SRL, SRL-C, and SRL-XT pumps have anti-friction bearings that must be lubricated with oil
before you start the pump.
1. Flush the cylinder or frame liner with oil in order to remove any grit or dirt that might have entered
the bearing housing during shipment or installation.
2. Refill with the proper lubricating oil until it reaches the line on the oil sight glass.
For more information, refer to Lubricating oil requirements and Oil volumes sections.
3. On the bearing cover, use the grease fitting in order to fill the cavity with grease.
This seals the cover and prevents foreign matter from entering the bearing housing. For information
about the correct grease to use for the seal, see Grease seal requirements.
5.3.1 Lubricating oil requirements
It is the responsibility of the oil vendor to supply a suitable lubricant. Make sure that the oil has these
qualities:
• Well-refined, premium to heavy duty type (API)
• Filtered mineral oil with non-foaming characteristics
• Free from water, sediment, resin, soaps, acid, and fillers of any kind
• Contains a protective agent against rust and wear
An SAE-20 to 30 grade with these characteristics is recommended:
