Overview of Primary Product

Typical Specification for Series 1510 Base Mounted,
Flexible Coupled, End-Suction Pumps
Furnish and install pumps with performance characteristics
as shown on plans. Pumps shall be base mounted, single
stage, end suction design with a foot mounted volute to
allow removal and service of the entire rotating assembly
without disturbing the pump piping, electrical motor
connections or pump to motor alignment.
A CSA certified condition monitor shall be installed on
the pump power end to continuously measure vibration
and temperature at the outboard bearing. Vibration
modes shall be based on ANSI/HI 9.6.4-2009 and ISO
101816 recommended levels. Vibration alarms shall
be at 100% increase over pump baseline. Minimum
vibration of 0.125 inch/sec is required to avoid nuisance
tripping. A high vibration alarm shall be at 0.50 inch/
sec. Temperature alarm shall be at 195°F (91°C). The
condition monitors’ electronics shall be potted in epoxy
and surrounded by a stainless steel enclosure. Accuracy
shall be +/- 15% within an ambient temperature range of
-40°F to 212°F (-40°C to 100°C).
Pump volute shall be Class 30 cast iron with integrally-
cast pedestal support feet. The impeller shall be cast
bronze enclosed type, balanced to ANSI/HI 9.6.4-2009
balance grade G6.3 and keyed to the shaft and secured
by a locking capscrew.
The liquid cavity shall be sealed off at the pump shaft
by an internally-flushed mechanical seal with ceramic
seal seat and carbon seal ring, suitable for continuous
operation at 225°F (107°C). A replaceable bronze shaft
sleeve shall completely cover the wetted area under
the seal.
Pump shall be rated for minimum of 175 psi (12 bar)
working pressure. Volute shall have gauge tappings at
the suction and discharge nozzles and vent and drain
tappings at the top and bottom.
The pump(s) vibration limits shall conform to Hydraulic
Institute ANSI/HI 9.6.4-2009 for recommend acceptable
unfiltered field vibration limits (as measured per
ANSI/HI 9.6.4-2009 Figure 9.6.4.2.3.1) for pumps with
rolling contact bearings.
Baseplate shall be of structural steel or fabricated steel
channel with fully enclosed sides and ends, and securely
welded cross members. Grouting area shall be fully
open. The combined pump and motor baseplate shall be
sufficiently stiff as to limit the susceptibility of vibration.
The minimum baseplate stiffness shall conform to ANSI/
HI 1.3-2009 for Horizontal Baseplate Design standards.
The seismic capability of the pump shall allow it to
withstand a horizontal load of 0.5g, excluding piping
and/or fasteners used to anchor the pump to mounting
pads or to the floor, without adversely affecting
pump operation.
A flexible type, center drop-out design coupler, capable
of absorbing torsional vibration, shall be employed
between the pump and motor. Pumps for variable speed
application shall be provided with a suitable coupler
sleeve. The coupling shall be shielded by a dual rated
ANSI B15.1 & OSHA 1910.219 compliant coupling
guard and contain viewing windows for inspection
of the coupling.
Motor shall meet NEMA and EISA 2007 (where applicable)
specifications and shall be of the size, voltage and
enclosure called for on the plans. Pump and motor shall be
factory aligned, and shall be realigned by the contractor
per factory recommendations after installation.
The pump(s) selected shall conform to ANSI/HI 9.6.3.1
standards for Preferred Operating Region (POR) unless
otherwise approved by the engineer.
Each pump shall be factory hydrostatically tested per
Hydraulic Institute standards. It shall then be thoroughly
cleaned and painted with at least one coat of high grade
paint prior to shipment.
The pump(s) shall be manufactured, assembled and
tested in an ISO 9001 approved facility.
Pumps shall be Series 1510 as manufactured by Xylem
Bell &Gossett or equal.
