2 Section 633 Page VIKING UNIVERSL XPD 676 PUMPS - FULL COMPLINCE with PI 676 STNDRDS SERIES 4223X & 4323X Features Required by PI 676 that are standard in XPD 676 series few of the key features that are required for full compliance include: PI 682 Seal. Viking s seal chamber will accept almost any customer-specified brands and types of PI 682-compliant Category 1, 2 or 3 cartridge mechanical seals, and can provide PI seal plans to meet application requirements. Standard seal is a category 2 single mechanical seal. Carbon vs. silicon carbide with PI Plan 13. 3mm corrosion allowance above Maximum llowable Working Pressure (MWP). The XPD 676 has an additional 3mm corrosion allowance built into all pressure containing components over and above our standard steel Universal Seal series pumps. 25,000 hour L-10 life on tapered roller bearings. Standard on all sizes at maximum speed and pressure. Steel castings to be normalized and tempered. Standard. High Strength Bolting. XPD 676 features high strength fasteners stamped with manufacturer s symbol and material codes, studs on some sizes. Threaded holes are drilled and tapped to minimum 1.5X stud diameter with minimum metal around the bottom of threaded holes at least 0.5X stud diameter plus 3mm corrosion allowance, per the specification. Casing drain and seal chamber vent. XPD 676 has cast-in casing drain with NSI Class 300 RF flange and seal chamber vent to completely drain the casing before maintenance. Mounting surfaces flat and parallel. The mounting feet of XPD 676 pumps are machined to 6.3µm Ra, with flatness tolerance of 25µm. The upper surface is machined parallel to the foot, and where the pump has both bracket and casing feet (N & R sizes), the feet are machined flat and parallel, in the same plane within 150 µm/m (0.002 in./ft) of distance between the mounting surfaces after the pump is assembled. Rectangular keyways. Viking cuts rectangular keyways with required fillets and includes the key with each pump. Tapered shaft extension on shafts larger than 2.5. Viking tapers the shaft extension on the R size for easy removal of the coupling half. Non-Destructive Evaluation of castings and post-weld evaluation of any necessary weld repairs using mag particle (MT) testing Certified hydrostatic testing to 1.5X MCP Certified performance testing in accordance with Section 3.6 of the Hydraulic Institute pump standards, at the specified viscosity (from 28 to 25,000 SSU), with data including speed, discharge pressure, suction pressure, power, and capacity. Packaging for long term storage, including corrosion inhibitor applied to exposed metal parts and metal port covers to protect internals from corrosion and contaminants Documentation to include, at a minimum: Certified dimensional outline drawing llowable flange loadings Cross-sectional drawing and bill of material Mechanical seal drawing and bill of material Performance curve Certified hydrostatic test data Material certifications (traceability) Weld procedure specification (WPS) Weld maps There are many more requirements of the PI 676 specification, and Viking has designed this pump to comply with all of them, as standard. dditional Features & Benefits Besides the features required by the PI 676 standard, Viking offers many additional features and benefits that our customers commonly request, including: Jacketing to melt ambient-temperature solids like bitumen before startup. The XPD 676 features jacketed bracket and casing as standard, with option for jacketed head. Opposite ports with reversible direction of flow are standard, for easy in-line piping and the ability to transfer product in either direction or strip a line of product. O-Ring seals on head and casing joints instead of gaskets for maximum sealing effectiveness. Optional labyrinth seals on bearing housing for longest bearing life by minimizing contamination (lip seals standard). Grease lubrication standard, enabling re-greasing of pump during operation, without the need for shutdown. End clearance is easily adjusted to compensate for wear over time or for higher temperatures or viscosities, by simply rotating the threaded bearing housing. 5 Non-destructive testing procedures Performance test procedures Performance test data Data sheets applicable to proposals, purchase and as-built Installation manual Operation and Maintenance manual Spare parts recommendations and price list List of drawings and submittals Shipping list Viking XPD 676 pumps carry a five year limited warranty.

Performance Curve Notes Performance curves can be electronically generated with the Viking Pump Selector Program. This program can be located on for the general public. For authorized distributors, this program can be found listed under the Products tab at Security passwords are required to access IDEXconnect. INLET CONDITIONS: The performance curves show Based on 10 (or 15) In.-Hg., which is the standard test condition. This is not the maximum vacuum capability of the pump. NPSH (Net Positive Suction Head): The NPSH R (Net Positive Suction Head Required by the pump) is given in the table below and applies for viscosities through 750 SSU. NPSH (Net Positive Suction Head vailable in the system) must be greater than the NPSH R. For a complete explanation of NPSH, see pplication Data Sheet D-19. FOR VISCOSITIES UP TO 750 SSU See NPSH R table below. FOR VISCOSITIES GRETER THN 750 SSU (NPSH R data not available): The performance curves are based on 10 or 15 In.-Hg. While vacuums up to 20 In.-Hg. will not generally result in any loss of capacity, it is recommended that the suction line size and possibly the pump port size be increased to hold the expected vacuum to 15 In-Hg. or less. Vacuum above 20 In.-Hg. should be avoided. Refer to General Catalog, Engineering Section 510 for information on determining line size. THIN LIQUIDS: pump capacity when handling 28 SSU liquids (solvents, etc.) is shown on the 38 SSU performance curve as a broken line. Pressure shown on broken line is maximum recommended for 28 SSU liquid. Horsepower for 28 SSU is same as 38 SSU at any given pressure. Carbon graphite bushings must be used handling 28 SSU liquids. MECHNICL EFFICIENCY: The Mechanical Efficiency (expressed in percent) can be calculated using the following formula: Mechanical Efficiency = (Differential Pressure, PSI) (Capacity, GPM) (100) (Horsepower, BHP) (1715) NPSH R FEET OF LIQUID (Specific Gravity 1.0), Viscosities up to 750 SSU Steel Externals Series 4223X and 4323X PUMP PUMPS SPEED, RPM SIZE HL KK LS Q, QS N R METRIC CONVERSION: The following table has been compiled for conversion to metric values.
