Wetted materials comply with FDA standards to limit leaching of PUMP A Unit of IDEX Corporation Cedar Falls, IA 157B / 4157B / 257B / 4257 BVIKING HYGIENIC SERIES INTERNAL gear PUMPSKey Features and Benefits: Splined shaft with one front-removable rotor.

2 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 ( ). Ensures cleanability. All INTERNAL wetted surfaces polished to minimum Ra of 32 in / m. Ensures cleanability.

3 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 / Cooling: Non-jacketed pump standard. Jacketing option for melting chocolate or other room-temperature solids prior to : HYGIENIC clamp ports conforming to ISO 2852 standard. Other HYGIENIC ports and ANSI compatible flange ports optional.

4 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 Port Optionsone port oriented downwards for drainabilityAdditional Options for COPI dler pin (shown as ) and rotation shown is as viewed from shaft end of PUMP A Unit of IDEX Corporation Cedar Falls, IA 157B / 4157B / 257B / 4257 BVIKING HYGIENIC SERIES INTERNAL gear PUMPSSEALED BEARINGS WITH FOOD-GRADE GREASEM eans no oil reservoir, no oil ANGLESM achined to a minimum radius of 1/32 in ( mm).
