SAFETY WARNINGS

Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.

WARNING

A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode, rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, property damage, and/or damage to the environment. All necessary measures must be taken to ensure over pressurization does not occur.

WARNING

Operation of any pumping system with a blocked suction and discharge must be avoided in all cases. Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is avoided.

WARNING

The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.

WARNING

Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly expand and result in a violent explosion and injury.

ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the current IOM available at www.gouldspumps.com/literature.

DESCRIPTION

Leakage of process liquid may result in creating an explosive atmosphere. Ensure the materials of the pump casing, impeller, shaft, sleeves, gaskets and seals are compatible with the process liquid.

Casing - The casing is horizontally split. The upper and lower halves are held together with capscrews plus studs on each side of each stuffing box to aid in disassembly/ reassembly. Flanged suction and discharge connections are located in the lower half of the casing and conform to ANSI 16.1/16.5 class 125/150. The casing is supported by integrally cast feet. Separate bearing housings are attached directly to machined fits in each end of the casing with capscrews. Fourteen of the 27 casings are double volute as tabulated on the next page.

*Casing uses a partial splitter.

125# flat face flanges are standard with 250# flat face available as an option. The casings are standard with two jack screws (except S group), two lifting lugs, two tapered dowel pins for alignment, and a 0.030 inch (.0762 cm) parting gasket.

The upper half casing is provided with a vent connection, a priming connection, and two stuffing box seal ring connections. The lower half is provided with two drain connections.

Impeller - The impeller is an enclosed, double suction design providing axial hydraulic balance. The impeller is dynamically balanced as standard when the diameter to width ratio is less than six. The impeller is key driven.

Wear Rings - Casing wear rings are supplied as standard to maintain proper running clearance and to minimize leakage between the suction and discharge chambers in the casing.

Each casing ring is held in place by a single anti-rotation pin, located in a milled slot at the horizontal parting surface. Optional impeller wear rings are available on all pump sizes. The impeller wear rings are held in position by axial set screws. Field installation of impeller rings requires a remachining of the impeller hubs. The casing rings remain the same for both the less-impeller ring and with-impeller ring designs.

Shaft - The shaft is a heavy duty design that minimizes deflection and vibration. The shaft deflection is a maximum of .002 in (.005 mm) at the stuffing box face under the worst operating conditions. The shaft on the M, L and XL group pump is completely dry with gasket seals between the impeller hubs and shaft sleeves. The S group does not have a completely dry shaft. The S group is standard with a 420 stainless steel shaft. The M, L, and XL sizes have an ANSI 4140 steel shaft standard, with an option for 316 stainless steel.

Shaft Sleeves -T he M, L and XL group pumps have standard Shaft Sleeves. They are keyed to the shaft at the

impeller and held axially in place using threaded sleeve nuts. The S group pumps are standard without shaft sleeves, but sleeves are available.

Stuffing Box - Non-asbestos stuffing box packing is standard. The stuffing box contains split lantern rings and renewable stuffing box throat bushings. Tapped openings are provided for water sealing from either the pump casing or an outside source. Bypass piping is optional. Two-piece investment cast 316SS non-quench glands are standard on all 3410 pumps.

Mechanical Seals - Mechanical seals are available as an option on the Model 3410. Oversize stuffing box bores are standard on pumps provided with factory installed mechanical seals, providing greater flexibility and an improved operating environment.

Pumps which are originally supplied with standard packed boxes can be converted to mechanical seals in the field. This conversion requires either a remachine of the stuffing boxes or a gland remachine to adapt to the existing stuffing boxes. Remachining of the stuffing box bores allows use of all standard Model 3410 mechanical seals and the standard I.D. pilot glands. Conversion to stepped sleeves would be required for balanced seals. Most unbalanced mechanical seals will fit in the standard packed box bores, but this requires remachining the I.D. pilot off the glands. In this case, the glands must be centered on the shaft or sleeve utilizing a feeler gauge.

Pumps supplied with mechanical seals can also be converted to packed boxes in the field. A cartridge conversion kit is available and includes a box of fittings, plus sleeves to convert to oversize bores to standard packed box bores.

Bearings - The Model 3410 is standard with double row ball thrust bearings and a single row deep groove ball bearing at the coupling end. There are only two sizes of bearing housings and bearings utilized on the complete Model 3410 product line. The S and M groups utilize identical bearings, as do the L and XL groups. The thrust bearing is held in position with a tapered snap ring and is locked in the thrust bearing housing to take any unbalanced axial thrust load. The radial bearing is free to float axially in the bearing housing taking radial loads only.

Grease lubrication is standard. Oil lubrication is optional and utilizes the same shaft, bearings, and bearing housings. Bearing cooling is available with oil lubrication only, and is required for temperatures over 250 degrees F (121 degrees C). The bearing housings are completely sealed by Inpro VBS bearing isolators.

Bedplates - Cast iron bedplates are furnished as standard. They include a drip collection chamber with a tapped drain connection and an opening suitable for grouting. Fabricated steel bedplates are available as an option.
