TYPICAL SPECIFICATIONS FOR SERIES HSC-S HORIZONTAL SPLIT CASE PUMPS SPECIFICATIONS.01 DOUBLE SUCTION, HORIZONTAL SPLIT CASE PUMPS (BASE MOUNTED) A MANUFACTURER: Contractor shall furnish and install new double suction horizontal split case pumps for chilled water and hot water heating systems as indicated on the drawings. Pumps shall be model HSC-S as manufactured by Bell & Gossett under base bid. Equivalent units may be submitted as deduct alternates. Pumps shall meet types, sizes, capacities, and characteristics as scheduled on the Equipment Schedule drawings. B DOUBLE SUCTION, HORIZONTAL SPLIT CASE PUMP (BASE MOUNTED) : 1. The pumps shall be long coupled, base mounted, single stage, double suction, horizontally split case design, in cast iron bronze fitted construction specifically designed and guaranteed for quiet operation. Suitable standard operations at F (7 C) and 17 psig (1 BAR) working pressure or optional operations at up to F (11 C) and 80 (19 BAR) or 0 psig (7 BAR) working pressures. Working pressures shall not be de-rated at temperatures up to F (11 C). The pump internals shall be capable of being serviced without disturbing piping connections or electrical motor connections.. A bearing housing shall supply support for a pair of heavy-duty regreaseable ball bearings. An inboard single row bearing will absorb thermal expansive forces while an outboard double row bearing will be clamped in place to absorb both radial and thrust loads and keep the rotating element in proper axial alignment. Bearings shall be replaceable without disturbing the system piping and shall be regreaseable without removal of the bearings from the bearing housing.. The impeller shaft shall be a solid 16 stainless steel shaft.. Pump shall be equipped with a pair of externally flushed mechanical seal assemblies in direct contact with the pump shaft. Seal assemblies shall be a Type 1 having a stainless steel housing, Buna bellows and seat gasket, stainless steel spring, and be of a carbon-ceramic design with the carbon face rotating against a stationary ceramic face.. Impeller shall be of the enclosed double suction type made of bronze, both hydraulically and dynamically balanced to ANSI/HI 1.1-1.-199, section 1..6.1..1, figure 1.6, balance grade G6. keyed to the shaft and fixed in the axial position. 6. A center drop-out type coupling, capable of absorbing torsional vibration, shall be employed between the pump and motor. On variable speed applications the coupler sleeve should be constructed of an EPDM material to maximize performance life. 7. The coupling shall be shielded by a dual rated ANSI B1.1, Section 8 and OSHA 19.19 compliant coupling guard and contain viewing windows for inspection of the coupling. 8. Pump volute shall be of a cast iron (rated for 17 psig [1 BAR] Max WP) or ductile iron (rated for 80 [19 BAR] or 0 psig [7 BAR] Max WP) axially-split design with flanges (17 psig [1 BAR] drilled for 1# ANSI companion flanges or optional 80 [19 BAR] and 0 psig [7 BAR] working pressures are drilled # flange drilled) and mounting feet integral cast into the bottom half of the casing. 80 (19 BAR) and 0 psig (7 BAR) 6x8xA s are cast iron. Suction and discharge flanges shall be on a common centerline in both the horizontal and vertical planes, and the volute shall include Bronze Casing Wear Rings, priming port, gauge ports at nozzles, and vent and drain ports. The upper half casing shall be capable of being removed without disturbing piping connections or electrical motor connections. 9. Pump seal flushing lines shall be mounted on the upper half pump casing. Sealing from an external source shall be possible for lubrication and/or cooling.. Motors shall meet scheduled horsepower, speed, voltage, and enclosure design. Pump and motors shall be factory aligned, and shall be realigned after installation by the manufacturer s representative. Motors shall be non-overloading at any point on the pump curve and shall meet NEMA specifications and conform to the standards outlined in EPACT 9. 11. Base plate 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 base plate shall be sufficiently stiff as to limit the susceptibility of vibration. The minimum base plate stiffness shall conform to ANSI/HI 1..-1997 for Horizontal Baseplate Design standards. 1. Base shall be capable of being field grouted. 1. The pump(s) selected shall conform to ANSI/HI 9.6..1 standards for Preferred Operating Region (POR) unless otherwise approved by the engineer. The pump NPSH shall conform to the ANSI/HI 9.6.1-1997 standards for Centrifugal and Vertical Pumps for NPSH Margin. 1. Pump rotation shall be righthand or lefthand as viewed from the pump end. 1. Pump manufacturer shall be ISO-9001 certified. 16. 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. 17. Each pump shall be factory hydrostatically tested per Hydraulic Institute standards and name-plated before shipment.
