VIKING® HEAVY DUTY PUMPS Section Page SERIES 4195 STANDARD CONSTRUCTION SERIES 4195 Pumps Cutaway View “AS”, “AK”, “AL” SERIES 4195 Pumps Cutaway View “G”, “GG”, “H”, “HJ”, “HL” GPM up to 75 (M³/Hr up to 17) ② (Nominal Rating) BALL BEARINGS (Standard Equipment) Pumps are equipped with inner cas­ ing ball bearing installed outside of mechanical seal and a radial thrust ball bearing permitting heavy-duty service up to 250 PSI (17 BAR). Bearings are “Sealed for Life”. PRESSURE LUBRICATION (Standard Equipment) (“AS”, “AK”, “AL” Sizes) A patented pressure lubrication system automatically lubricates the idler bushing. This system provides a constant film of liquid between the idler bushing and idler pin at a pressure equal to the pump discharge pressure regardless of pump rotation. DUCTILE IRON PARTS (Standard Equipment) (“AS”, “AK”, “AL” Sizes) Internal pumping gears (rotor and idler) are constructed of ductile iron for added strength in handling all types of liquids up to 15,000 SSU (3,300 cSt). “HL” size rotor also furnished in ductile iron. O-RING GASKETS (Standard Equipment) O-Ring gaskets are used between casing and head plate and between casing and relief valve or valve plates. Flat valve gaskets furnished on “G”, “GG”, “H”, “HJ” and “HL” size pumps. These gaskets provide a positive seal eliminating a chance for leakage at these points. Viking’s high-speed, heavy-duty Series 4195 pumps are available in capacities up to 75 GPM. These pumps can be furnished directly connected to a 50 Hz or 60 Hz motor. (See Series 4195D units shown on page 144.3.) All eight sizes of Viking Series 4195 pumps are furnished with single mechanical seals. This seal is a simple selfadjusting, non-leak method of shaft sealing located ahead of the casing ball bearing. The Series 4195 pumps are built for con­inuous or intermittent duty for t such applications as filtering, circulating, transferring, or booster service in general industrial, petroleum and marine uses. NOTE: “UL” listed pumps for handling LPGas require special construction. Externals are high strength cast iron. (Ductile Iron Casing on “AS”, “AK” and “AL” sizes). See Catalog Section 440 for details and pricing information. Model numbers for these pumps must be designated by a suffix -G, eg. GG4195-G or when used with a “D” drive, GG4195D-G. “UL” listed models must be equipped with a return-to-tank pressure relief valve. Maximum discharge pressure for “UL” listed models is 125 PSIG. ① Values shown represent minimums or maximums. Some special construc­ion or t consideration may be required before a cataloged pump can be ap­ lied to an p application involving maximum pressure or minimum or max­mum temperature i and/or viscosity. Certain models have restrictions in pressures and/or viscosities. See specifications, page 144.2, and perform­ nce curves, which can be a electronically generated with the Viking Pump Selector Program, located on www.vikingpump.com/pumpselector. ② Nominal capacities based on handling thin liquids. Metric conversions are based on US measurements and rounded to the nearest whole number. VIKING PUMP • A Unit of IDEX Corporation • Cedar Falls, IA
