Even higher pressures are possible withhigh fluid viscosities at reduced operating speeds (consultfactory). They are also capable of operating under suction liftconditions and operate equally well in either direction.The Universal Product Line has the broadest range ofsealing options of all pumps built by Viking. The stuffing boxon all sizes accepts packing, numerous component singlemechanical seals, or a wide variety of cartridge seals.The Universal Product Line is Viking Pump’s most versatileline of internal gear pumps due to the availability of manydesign and material options.1227A Series , 1327A Series :Viking Pump is the leader in internal gear innovation and thelatest development is the O-Pro Seal technology. The NEWUniversal Seal Product Line comes with the O-Pro GuardSeal factory installed. The Universal Product Line combinesthe tested reliability of the Universal pump & O-rings to createa robust seal and lubrication chamber, all in one.Dimensions – Stuffing Box Seal Chamber.13NPSH Required.14RELATED PRODUCTSStainless Steel, Non-Jacketed Pumps: Catalog Section 1701Cast Iron, Jacketed Pumps: Catalog Section 1402KK1127ASteel Externals, Jacketed Pumps: Catalog Section 1302KK227AOPERATING RANGENOMINAL FLOWMAXIMUM PRESSURETEMPERATURE RANGEVISCOSITY RANGESERIESGPMmhPSIBar F CSSUcSt227A Series 10 - 3202.3 - 7315010 120 to 500 85 to 26028 to 2,000,0000.1 to 440,0001227A Series 6 - 3201.4 - 7315010-15 to 350-25 to 17528 to 75,0000.1 to 17,00034227A Series 10 - 3202.3 - 7315010 120 to 500 85 to 26028 to 2,000,0000.1 to 440,000327A Series 600 - 1,600136 - 36420014 120 to 500 85 to 26028 to 2,000,0000.1 to 440,0001327A Series 475 - 1,280108 - 29020014-15 to 225*-25 to 105*28 to 750*0.1 to 165*4327A Series 600 - 1,600136 - 36420014 120 to 500 85 to 26028 to 2,000,0000.1 to 440,000* Range may increase with end clearance adjustment.

The heat transfer medium flows in a closed loop backto the boiler or heater. Applications include “melting” ambienttemperature solids like asphalt which solidify in the pumpwhen it cools, and maintaining precise temperature control inprocesses like manufacturing polymers and epoxy resins.Standard-Jacketed PumpsStandard-Jacketed pumps include series 227A & 4227A.They feature jacketing on the head and bracket only, and aretypically used for melting ambient temperature solids.Jacketed Bracket Series designed with an enlarged bearing housing.Used in conjunction with a spacer coupling permits easycartridge seal installation and removal in place withoutremoving the head and rotor/shaft. Seal options include packing, O-Pro Guard Seal, singlecomponent seals, cartridge lip seals and cartridge singleand double mechanical seals. Various seal flush plans areavailable. Steel externals for petroleum refineries, petrochemicalplants and similar customers who require highertemperature and higher working pressures than cast ironpumps can provideLS4227AJacketed Pump CutawayViking Universal Product Line pumpscarry a three year limited warranty.See catalog section 000 for details.
