Features & Benefits
HELICAL IN-LINE STANDARD FEATURES • Shaft material is wear resistant, high carbonsteel that provides stable non-grooving surface for oil seal contact. • AUTOVENT™ breather seals dirt and moisture out while allowing the gear case to breathe during startup and cool down. • UNICASE™ one-piece housing is torsionally sti, machined in one pass, has extreme accuracy, and eliminates the split case leakage path. • Primer paint covers all exterior surfaces of the housing, providing excellent base corrosion protection. NORDBLOC.1® STANDARD FEATURES • NORDBLOC.1® units are ﬁ lled at the factor y with the proper quantity and type of lubrication. Oil ﬁ ll before shipping prevents damage from dry start-ups. • Shaft material is wear resistant, high carbon steel that provides stable non-grooving surface for oil seal contact. • Outside diameter of oil seals is nitrile rubber. Direct connection of seal to housing eliminates bolt-on covers and centers the seal, eliminating the potential for leakage.
General Description
1. Determine the actual horsepower or kW requirements of the application from the pump performance curve, which can be electronically generated with the Viking Pump curve generator, located on www.vikingpump.com, or specifications from other equipment. 2. Based on the horsepower or kW requirement, go to the closest higher HP or kW page. Example: For a 7.1 HP requirement, go to the 7.5 HP catalog page. Then find the reducer which most closely matches your speed requirements. 3. Make sure the service factor for the reducer selected is greater than the service factor from the Service Factor Table on page 6. The Service Factory Table provides different service factors based on the length of service per day, the load classification (uniform, moderate, shock, heavy shock) and the type of drive. A table of driven load classifications is also included on page 616.6 to help determine the service factor to use. 4. Next, determine the part number of the Nord reducer. Part numbers can be created from the catalog pages (examples below). Note: the “-“ is required between each field.
