Mechanical Compatibility & Heavy-Duty Metallurgy
1:1 Bolt-On Dimensional Compatibility
Identical port-to-port dimensions, center-line height, and baseplate mounting holes. Swap existing Viking pumps without modifying existing piping, valves, or motor couplings.
Crescent Internal Gear Geometry
Precision CNC-machined rotor and idler gears separated by a heavy-duty crescent partition. Delivers smooth, non-pulsating positive displacement for resins, chocolate, bitumen, and polymers.
Full Envelope Heating Jackets
Integral steam or thermal oil heating jackets on casing and front cover prevent crystallization and maintain high fluid temperatures during cold startup.
Interchangeable Wear Parts & Rebuild Kits
Complete rebuild kits available: idler gears, bronze/carbon bushings, nitrided shafts, crescent heads, and mechanical seals engineered to fit original Viking pumps.

Viking Pump® Replacement Engineering FAQs
Q: Can I replace an existing Viking H or K series pump without modifying piping?
A: Yes. Orbi Pump NYP series pumps feature identical flange face-to-face dimensions, suction/discharge centerline heights, and baseplate mounting hole locations as the corresponding Viking H, HL, K, KK, L, LQ, and Q models. Pipework, valves, and motor alignments can remain completely undisturbed.
Q: Can Orbi Pump supply individual replacement parts to repair an existing Viking pump?
A: Yes. We supply drop-in replacement rotors, idler gears with pressed-in bushings, idler pins, crescent heads, shaft sleeves, and mechanical seal cartridges designed to fit original Viking pumps.
Q: What materials are available for corrosive or abrasive fluids?
A: Standard housings are HT250 gray cast iron or QT500 ductile iron. For corrosive fluids, we cast 304, 316, and 316L stainless steel. For abrasive or pigment-loaded media, we provide carburized 40Cr/42CrMo gears, tungsten carbide shaft sleeves, and SiC/SiC mechanical seals.
Q: How can I cross-reference my Viking nameplate to the correct Orbi Pump model?
A: Simply send a photograph of the Viking pump metal nameplate or provide the model code (e.g., HL4124A, KK124A) along with your pumping medium, temperature, and required operating pressure. Our engineering team returns a 1:1 cross-reference quotation within 2 hours.
