PSG

What PSG does

PSG (Pump Solutions Group) is a global manufacturer of pumps, compressors, flow measurement instruments, and chemical dispensing equipment, operating as a wholly-owned subsidiary of Dover Corporation (NYSE: DOV) within its Pumps & Process Solutions segment. The business is organized around 16+ heritage brands — including Wilden (inventor of air-operated double-diaphragm pump technology), Blackmer, Mouvex, Hydro, Malema, Almatec, Neptune, Griswold, Quattroflow, and others — each addressing specialized fluid-handling niches. PSG's product portfolio spans positive displacement pumps (AODD, gear, peristaltic, eccentric disc, screw, rotary vane, lobe), ANSI centrifugal and cryogenic centrifugal pumps, reciprocating gas compressors, regenerative turbine pumps, single-use biotech pumps, mixers, sensors, and chemical dispensing equipment, supported by patented technologies such as Pro-Flo SHIFT air distribution, Chem-Fuse and Pure-Fuse integral piston diaphragms, Equalizer surge dampeners, and AccuPro pressure regulation. End markets include oil & gas, chemical process, biotech/biopharma, food & beverage, semiconductor, medical, water & wastewater, personal care, paint & coatings, and transport.

PSG makes money primarily by manufacturing and selling industrial hardware (pumps, compressors, flow meters, dispensers) and earning aftermarket parts and service revenue from its installed base, with a smaller recurring stream from the Hydro Connect cloud-based IoT platform that monitors chemical and water usage for dispensing customers. Pricing is quote-based, project-specific, and typically structured as multi-year contracts for enterprise customers, while mid-market buyers access products through authorized distributors and an own e-commerce storefront. The company goes to market through a global channel partner network spanning 100+ countries combined with direct enterprise field sales and applications engineering support for large industrial accounts in oil & gas, chemical process, and biopharma. PSG holds extensive industry certifications (ISO 9001/14001/45001, ATEX, UL, FM, 3A, EHEDG, FDA CFR 21.177, USP Class VI, EC 1935/2004, Hydraulic Institute PTLAP) that are required qualifications for regulated end markets and form a meaningful barrier to entry.

The company is headquartered in Downers Grove, Illinois, with manufacturing and engineering operations in the United States (Grand Terrace, Grand Rapids, Cincinnati, Boca Raton, San Jose, Arden Hills, Roseville, North Hollywood), Europe (Auxerre France, Duisburg and Bersenbrück Germany, Finning Germany), China (Tianjin, Suzhou), India (Chennai manufacturing, Bengaluru sales), and Australia (Cromer). PSG has pursued a steady inorganic growth strategy, completing acquisitions of Dositec Sistemas S.L. in 2021, Malema Engineering Corporation in 2022 (for $225 million plus up to $50 million contingent), Cryogenic Machinery Corp. in January 2025, and ipp Pump Products GmbH in June 2025, while continuing to launch new products such as Hydro's AccuMini dispenser, Malema's M-2300 ultrasonic flow meter for semiconductor applications, and the CRYO-MACH cryogenic centrifugal series integrated under Blackmer.
