What PG Group (dba PG Flow Solutions) does

PG Flow Solutions is a Norwegian engineering and manufacturing company founded in 1982 by Per Gjerdrum that designs, builds, assembles and tests custom-engineered pump and flow solutions for marine, energy, aquaculture and industrial customers. The portfolio centres on propeller pumps (PG-600, up to 5,000 m³/h), high-torque agitators (PG-Submix, 40+ years and 5,000+ installations), Hermetic canned motor pumps for cryogenic-to-high-temperature hazardous service, VSEP vibratory membrane filtration (up to 99.9% nitrogen removal), Fournier Rotary Press dewatering, PG-Hydroflow non-mechanical live-fish transfer, ballast water treatment (PG-Hyde, USCG approved), and fully engineered Fire Suppression Systems (gas, dry powder, water mist, foam). The in-house facility in Sande i Vestfold includes steel fabrication, assembly, automation, and two test pits rated for 10,000 m³/h flow and 2,000 bar pressure, supporting bespoke skid-mounted systems for offshore, energy, aquaculture and industrial applications.

The business model is direct B2B sales of quote-priced, project-specific engineered systems, supplemented by aftermarket Lifecycle Services (spare parts, repairs, on-site overhaul, commissioning, troubleshooting, testing, service agreements) and dedicated fire suppression contracts. Go-to-market mixes direct enterprise sales organised by business unit (Energy & Marine, Landbased Aquaculture, Lifecycle Services, Fire Suppression Systems), a two-person PG Sweden team, and an international agent network covering the Middle East, Brazil, China, Japan and Turkey. Customer evidence spans Aker BP (Hod field), Equinor (K-Lab), Kvaerner (Verdal), VARD and YARA (Yara Birkeland autonomous container vessel), Sølvtrans and Aas Mekaniske Verksted (wellboats), Nova Sea and Sterner (smolt facilities), and VEAS (Slemmestad wastewater treatment), indicating multi-vertical enterprise demand.

The company is headquartered in Sande i Vestfold, Norway, with wholly-owned subsidiaries Calder Ltd (Worcester, UK), Cflow Fish Handling AS (Ålesund, Norway) and PG Cleanwater Solutions, plus a substantial minority stake in Norwegian dewatering specialist Lange Lyche Teknisk AS (LLT). Since July 2022, PG Flow Solutions has been 100% owned by the founding Gjerdrum family. The group maintains ISO 9001:2015, ISO 14001:2015, ISO 3834-2, DNV-GL manufacturing survey approval, DNV type approval for fire suppression, Achilles JQS pre-qualification for the energy sector, and a US Coast Guard certificate for the PG-Hyde ballast water treatment system. Headcount stood at approximately 110 employees as of October 2025.
