Take away these eight standard features and you ll have a pump like everyone else s. True Back Pullout A B&G standard in design and construction.

Internally Self-Flushing Mechanical Seal This design is way ahead of its time. This unique seal design is proven in many years of service.

This standard feature ensures maximum seal face lubrication, heat dissipation and debris removal without vulnerable, external flush tubing.

Computer Controlled Impeller Balancing 1 impellers are balanced to ANSI/HI 9.6.-2009, balance grade G6.3 standards.

Diameters are computer selected at the factory to furnish assurance that your capacity requirements will be met.

This integrally cast foot ensures that the alignment between the volute and motor assembly is maintained.

This feature is equally important on hot water applications.

3 Take away these eight standard features and you ll have a pump like everyone else s. True Back Pullout A B&G standard in design and construction.ease in service is assured, while piping and motor remain undisturbed. Extended delays for repairs are virtually eliminated. Internally Self-Flushing Mechanical Seal This design is way ahead of its time. This unique seal design is proven in many years of service. It requires no special external flushing provisions, since the design provides for constant efficient flushing action internally. This standard feature ensures maximum seal face lubrication, heat dissipation and debris removal without vulnerable, external flush tubing. The internal flushing action passes two and a half to three times the flow over the seal faces compared to a few GPM for conventional, stuffing-box designed pumps. Computer Controlled Impeller Balancing 1 impellers are balanced to ANSI/HI , balance grade G6.3 standards. This method of computer balancing Impellers provides for quiet, efficient, vibration free performance. Diameters are computer selected at the factory to furnish assurance that your capacity requirements will be met. Solid-Foot Mounted Volute All Series 1 pumps are provided as standard with an integrally cast volute foot located directly beneath the pump volute. This integrally cast foot ensures that the alignment between the volute and motor assembly is maintained. Without solid support beneath the volute, the piping weight alone will cause distortion which can lead to premature failure of the bearings, shaft and mechanical seal. This feature is equally important on hot water applications. The Series 1 volute foot provides a solid foundation and eliminates the deflections which would otherwise exist within an unsupported overhung volute during the normal thermal expansion of the system piping against the volute. Center Drop-Out Spacer Coupling Unlike conventional jaw type or rigid style couplings, a center drop-out spacer coupling allows removal of the bearing frame and rotating element without disturbing the pump end pipe alignment or motor electrical connections. ANSI/OSHA-Compliant Coupling Guard The coupler guard complies with ANSI B1.1 and OSHA The guard offers increased protection against potential injuries and is standard on all 1 pumps. The guards include slotted viewing windows for easy inspection. Heavy Duty, Rugged Baseplate The Bell & Gossett fabricated heavy duty baseplate is supplied as standard on every Series 1 pump. Unlike rolled steel and C channel baseplates, the Series 1 baseplate provides a heavy duty saddle assembly, full seam welds, closed baseplate ends and an open top to provide ease of access for proper equipment grouting. Patented i-alert TM Condition Monitor Continuously measures vibration and temperature at the outboard bearing and automatically indicates when pre-set levels of vibration and temperature have been exceeded, so that changes can be made before failure occurs. A visual indication of pump health makes walk-around inspections more efficient and accurate. This onboard pump intelligence helps minimize life-cycle costs while maximizing performance. 3

4 Technical Data BALANCE STANDARDS Impellers are balanced to Hydraulic Institute Standards ANSI/HI The allowable residual unbalance in the impeller rotating assembly conforms to ANSI grade G6.3 (Ref. ISO 190). ANSI Balance Quality Grades of G2. and G1 for the rotating assembly are also available. Consult your local Bell & Gossett Representative for additional details. VIBRATION LIMITS Series 1 pumps conform to Hydraulic Institute ANSI/HI for recommended acceptable unfiltered field vibration limits (as measured at the pump bearings per ANSI/HI , Figure ) for pumps with rolling contact bearings. OVERALL DISPLACEMENT (Unfiltered) PUMP SPEED RPM Peak to Peak-Mils (.001 ) SEISMIC CAPABILITIES Series 1 pumps are capable of withstanding a horizontal load of 0.g* without adversely affecting pump operation. *Piping and/or fasteners used to anchor the pump to the mounting pads on the floor are excluded.

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 and ISO 18 recommended levels. Vibration alarms shall be at 0% increase over pump baseline. Minimum vibration of 0.12 inch/sec is required to avoid nuisance tripping. A high vibration alarm shall be at 0.0 inch/ sec. Temperature alarm shall be at 19 F (91 C). The condition monitors electronics shall be potted in epoxy and surrounded by a stainless steel enclosure. Accuracy shall be +/- 1% within an ambient temperature range of -0 F to 212 F (-0 C to 0 C). Pump volute shall be Class 30 cast iron with integrallycast pedestal support feet. The impeller shall be cast bronze enclosed type, balanced to ANSI/HI 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 22 F (7 C). A replaceable bronze shaft sleeve shall completely cover the wetted area under the seal. Pump shall be rated for minimum of 17 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 for recommend acceptable unfiltered field vibration limits (as measured per ANSI/HI Figure ) 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 for Horizontal Baseplate Design standards. The seismic capability of the pump shall allow it to withstand a horizontal load of 0.g, 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 B1.1 & OSHA 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 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 1 as manufactured by Xylem Bell &Gossett or equal. 11
