Operating Range:Heavy Duty, Hygienic Internal Gear Pumps for COP or CIP
Shown with Optional Wing Nuts on Head
Nominal Flow Rates:
Series DescriptionViking’s Hygienic Series positive displacement pumps are designed to conform to International standards for sanitary processing of foods, beverages, fine chemicals, pharmaceuticals and personal care products where the pump will be subject to frequent cleaning, using either Clean In Place (CIP) or Clean Out of Place (COP)/Strip Clean Methods.
These pumps are available with compliance to major hygienic standards including 3-A and EHEDG Type EL, Class 1. Wetted materials comply with FDA standards to limit leaching of substances.

VIKING HYGIENIC SERIES INTERNAL GEAR PUMPS
Key Features and Benefits:● Splined shaft with one front-removable rotor. Faster
disassembly and reassembly vs. timed pumps with two rotors. (Patent pending)
● One shaft seal. Half the seal replacement cost of timed pumps with two shaft seals.
● Front-loading seals. Eliminates entrapment areas in the stuffing box common to other gear pumps, simplifies maintenance. (Patent pending)
● Mechanical seal with Carbon/Silicon Carbide faces standard. Provides greater seal life than Carbon/Ceramic or Carbon/SS faces standard on most pumps. Many seal options available.
● Sealed bearings with food-grade grease. No oil reservoir to enable water infiltration or condensation, no oil changes.
● Five minute end clearance adjustment by rotating the bearing housing, vs. 2-4 hours shimming on most lobe or CP pumps.
● FDA conforming wetted materials. Ensures product integrity.
● All internal angles machined to a minimum radius of 1/32 inch (0.08mm). Ensures cleanability.
● All internal wetted surfaces polished to minimum Ra of 32µin / 0.8µm. Ensures cleanability.
● Wetted part material traceability available. Ensures the ability to trace the part back to original batch.
● Reversible direction of flow. Enables stripping product from the line to minimize product loss and improve cleaning efficiency.
● Flow proportional to speed regardless of system pressure. Enables more accurate batching or metering than centrifugal pumps which are highly sensitive to system pressure.
● Locating pin on casing. Ensures pump head cannot be reassembled incorrectly.
● Removable idler pin allows replacement of pin only instead of head and pin assembly. (Patent pending)
Standards and Options:
Seals:● Single mechanical seal standard.
Options: double mechanical seal with flush/quench or single or double O-ring seal.
Heating / Cooling:● Non-jacketed pump standard. Jacketing option for
melting chocolate or other room-temperature solids prior to startup.
Porting:● Hygienic clamp ports conforming to ISO 2852 standard.
Other hygienic ports and ANSI compatible flange ports optional.
● Standard and optional port sizes listed in specifications, page 6.
● Opposite ports standard, 90° ports optional. The port with a casing groove (shown as V) needs to be used as the suction port for the pump’s primary rotation which is clockwise from the shaft end in orientations A, B, D, E, G, H, I and L . The purpose of this suckback groove in the casing is to cause liquid to flow from the higher pressure discharge side behind the rotor to the lower pressure suction side to cool and lubricate the shaft seal, and ensure complete flushing during CIP. Due to the casing groove location, orientations C, F, J and K (counterclockwise rotation) will require a special casing.
CIP-able Port Optionsone port oriented downwards for drainability
Additional Options for COP
Idler pin (shown as ) and rotation shown is as viewed from shaft end of pump.

VIKING HYGIENIC SERIES INTERNAL GEAR PUMPS
① Standard ports are sanitary clamp. Sanitary clamp port dimension is O.D. of pipe, not O.D. of ferrule, which is about 1/2” greater diameter. Optional flange ports suitable for use with Class 150 steel or stainless steel companion flanges or flanged fittings.
