IMO Pump

What IMO Pump does

IMO Pump, founded in 1931 in Sweden by Carl Montelius and Bengt Ingestrom as Aktiebolaget IMO-Industri, is a U.S.-headquartered manufacturer of rotary positive displacement three-screw pumps, CIG crescent internal gear pumps, and specialty marine centrifugal pumps. The company operates three ISO-certified manufacturing facilities — Monroe, NC (headquarters, R&D, ISO 9001), Columbia, KY (gear and high-volume three-screw pumps, ISO 9002), and Warren, KY (Warren centrifugal pumps) — and is a business unit of CIRCOR International (NYSE: CIR), which acquired the company in 2017. Its three-screw design, invented by founder Montelius in 1923, uses precisely calculated rotor thread profiles that prevent vibration and enable silent, high-speed, high-pressure operation; the company states "millions" of these pumps are in service globally.

The product portfolio spans more than 15 three-screw series (3E, 3D, 6D, 12D, 12L, Tritec, etc.) covering 1–3,300 GPM and pressures to 4,500 PSIG, plus 54 single and over 1,300 double CIG gear pump configurations rated to 5,000 PSIG, and Warren centrifugal pumps for marine seawater, cargo oil, and ballast service. IMO serves hydrocarbon and chemical processing, crude oil transport, Navy and commercial marine, power generation, pulp and paper, hydraulic elevators, and general industrial machinery. Pumps can be supplied to full US Navy shock, vibration, and noise specifications and hold ABS Type Approval (Nos. NN1732416, NN1732419) for marine applications.

Revenue is generated through hardware sales of pumps, aftermarket parts and repair kits (supported by a searchable parts database covering current and obsolete models), and professional services tied to documentation and technical support. The go-to-market is enterprise field sales via U.S./Canadian and Latin American regional representative networks, augmented by the Colfax Fluid Handling Pump Selector Program (cfx-selector.com), the CentralApps portal for parts ordering and order status, and an extensive content library (PumpTips knowledge base, service manuals in English and Spanish, CAD drawings). Pricing is quote-based with no public disclosure. IMO holds no standalone funding; growth is funded through its parent CIRCOR.

Core offering

IMO Pump manufactures rotary positive displacement three-screw pumps and CIG Crescent Internal Gear pumps, plus specialty marine centrifugal pumps. The company supplies engineered pump models and aftermarket parts and repair kits through regional field sales representatives serving industrial, hydrocarbon processing, marine, and military customers across North America and Latin America, supported by ISO 9001/9002 production and ABS/US Navy qualified manufacturing.

Product overview

IMO Pump is a manufacturer of rotary positive displacement pumps, producing three distinct core product lines: 3-Screw Pumps (invented by founder Carl Montelius in 1931 as the world's first multiple screw pump), CIG (Crescent Internal Gear) Pumps, and Navy/Marine Pumps including centrifugal pumps from the Warren facility. The 3-Screw Pumps product line comprises over 15 series variants (3E, 3G, 3D, 6D, 12D, 12L, 4U/4T, 6U/6T, 8L, 413IC, C324, T324, 323F, Emtec, Tritec, 4SFC, 4VKC, USNP/4PIC) serving flow rates from 1 to 3300 GPM and pressures up to 4500 PSIG. The company also provides supporting tools including the Colfax Fluid Handling Pump Selector Program, a searchable parts database, downloadable service manuals, CAD drawings, and technical resources. Manufacturing is conducted under ISO 9001 Quality Management Systems at Monroe, NC (headquarters and R&D) and Columbia, KY facilities. IMO Pump is a business unit of CIRCOR, acquired in 2017.
