Bearings are Sealed for Life.

2 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 OVER pressure RELIEF VALVE (Standard Equipment)Permits bypassing of liquid from discharge to suction side of pump. Prevents build up of pressure in dis-charge line. GG , HJ and HL size valve mounts on pump head. AS , AK and AL size valve mounts on pump RING GASKETS(Standard Equipment)O-Ring gaskets are used between casing and head plate and between casing and relief valve or valve plates.

3 Flat valve gaskets furnished on GG . HJ and HL size PUMPS . These gaskets provide a positive seal eliminating a chance for leak-age at these s high-speed, HEAVY - duty Series 4193 and 493 steel external PUMPS are available in capacities up to 75 GPM. These PUMPS can be furnished directly connected to a 50HZ or 60 HZ motor. Series 493 is designed for vertical or horizontal flange mount installations where space is at a premium. (See pages ) Series 4193 is designed for foot type horizontal PUMPS are built for continuous or intermittent duty for such applications as filtering, circulating, transferring, or booster service in general industrial, petrochemical and other are furnished as standard with mechanical seal construction to minimize liquid loss and for shaft protec-tion.

4 The thrust control provides micrometer adjustments for accurate rotor and shaft positioning to help you keep operating with new-pump efficiency through years of HEAVY - duty s famous gear-within-a-gear principle has only two moving parts. It is the secret of dependable efficient operation of all positive displacement VIKING rotary PUMPS . Positive displacement of liquid is accomplished by the meshing of rotor and idler gear every revolution of the pump shaft, a definite amount of liquid is drawn into the pump through the suction 4193 Cutaway View 10-20-30 GPM Sizes ( M /Hr) pressure Range250 PSI (17 BAR) for 100 SSU (20 cSt) and above150 PSI (10 BAR) for 38 to 100 SSU (3 cSt to 20 cSt)100 PSI (7 BAR) for below 38 SSU (3 cSt) Temperature Range0 F.

6 They are equipped with steel, internal type, over- pressure relief valve. The steel used meets ASTM designation A216 Grade WCB specifications. All PUMPS are equipped with horizontal 300 lb. ANSI flanged ports and conform to most requirements of API 676. A simple, efficient, unbalanced single mechanical seal with Buna-N gaskets, carbon and Ni-Resist faces is standard. Other seal types and materials available on request.
