What Hydro-Pac does

Hydro-Pac, Inc. is a privately held U.S. manufacturer of high-pressure gas compressors, liquid pumps and pressure vessels, founded in 1972 and operating from a 28,000 sq ft facility in Fairview, Pennsylvania. The company's product portfolio centers on five core equipment lines — LX-SERIES and FLEXI-POWER gas compressors, Li'l CRITTER compressors and pumps, and FC-SERIES liquid pumps — supplemented by custom pressure vessels and packaged turn-key systems. Underlying every product is a hydraulically driven, force-balanced intensifier architecture with a patented free piston design that allows seal maintenance without hydraulic-section removal and supports discharge pressures up to 175,000 psig for gas and 200,000 psig for liquid.

Hydro-Pac sells predominantly to enterprise customers across at least seven verticals: alternative fuels (LX-SERIES hydrogen fueling), automotive airbag inflator filling, hot and cold isostatic pressing (H.I.P./C.I.P.), gas-assist injection molding, cylinder filling, pressure testing, and research/special applications including subsea, diamond manufacturing and hydrogen test carts. Pricing is quote-based with no list pricing disclosed; revenue streams include one-time custom equipment sales, turn-key packaged systems, and aftermarket service and parts. The company holds ASME Section VIII Divisions 1, 2 and 3 certification and can ship to PED (Europe), KHK (Japan), CSA (Canada) and SELO (China) markets, and operates EAR/ITAR-compliant export controls. Distribution is direct from Pennsylvania globally, with a sister company — Nihon Hydro-Pac in Tokyo and Gifu — handling Japan sales, distribution and service. The firm employs 11–50 people, has no disclosed external funding and is described as founder/management-controlled.

Core offering

Hydro-Pac designs and manufactures high-pressure gas compressors (up to 175,000 psig) and high-pressure liquid pumps (up to 200,000 psig), as well as custom pressure vessels, based on a patented hydraulically driven intensifier architecture. The company sells standalone equipment, custom turnkey packaged systems with PLC controls, valves, piping, and gas storage, plus aftermarket service and replacement parts, to industrial, energy, research, and safety customers worldwide.

Product overview

Hydro-Pac is an industrial equipment manufacturer offering a complete line of high-pressure gas compressors, liquid pumps, and pressure vessels. The product portfolio centers on three main compressor lines (LX-SERIES for low-pressure hydrogen applications, FLEXI-POWER for high-pressure industrial use, and Li'l CRITTER for small-scale lab applications) and two liquid pump lines (FC-SERIES for production-scale 10,000-200,000 psi applications and Li'l CRITTER for research applications). These core products are complemented by pressure vessels and turnkey packaged systems (compressor systems and pump systems) that bundle equipment with PLC controls, valves, piping, and storage. Hydro-Pac also designs custom equipment for special applications including subsea, diamond manufacturing, and hydrogen testing. The company operates from a 28,000 sq ft facility in Fairview, PA and has a sister company (Nihon Hydro-Pac) in Japan.

Broad incumbents

• Sundyne (Honeywell): Sundyne manufactures high-pressure API 674 reciprocating pumps and centrifugal compressors for oil & gas, petrochemical, and industrial process applications — overlapping Hydro-Pac's high-pressure pump/compressor capability but at much broader scale and with a wider process-industry focus.
• Atlas Copco: Atlas Copco is a global industrial compressor and vacuum OEM with extensive high-pressure product lines, service network, and digital offerings — a broad incumbent alternative to Hydro-Pac's specialty compressor portfolio for customers prioritizing scale and global aftermarket coverage.
• Chart Industries: Chart Industries is a large cryogenic and industrial gas equipment manufacturer with a broad hydrogen value chain (including PDC Machines), competing with Hydro-Pac in hydrogen compression and high-pressure gas handling via standardized and engineered-to-order solutions.
• Flowserve Corporation: Flowserve is a major manufacturer of industrial pumps, valves, seals, and related flow-control equipment serving oil & gas, power, and chemical markets — overlapping Hydro-Pac's high-pressure liquid pumping capability as part of a much broader engineered-product portfolio.

Direct peers

• Haskel International: Haskel manufactures high-pressure liquid pumps, gas boosters, and air-driven amplifiers used in gas compression, pressure testing, and gas assist injection molding — directly overlapping Hydro-Pac's FC-SERIES pumps and intensifier-based compressor applications across industrial and aerospace customers.
• Bauer Compressors: Bauer designs and produces high-pressure gas compressors (breathing air, industrial gas, and specialty applications) up to and beyond 6,000 psi with custom configurations — competing head-to-head with Hydro-Pac in industrial, research, and alternative-fuel compression use cases.
• Maximator (Schmidt + Clemens Group): Maximator manufactures high-pressure pumps, gas compressors, valves, and hydraulic intensifiers for hydrogen, gas assist injection molding, pressure testing, and oil & gas — directly comparable to Hydro-Pac's intensifier-based portfolio with similar pressure ranges and application breadth.
• Hammelmann: Hammelmann produces very high-pressure plunger pumps (up to 300,000 psi) for industrial cleaning, hydrostatic testing, and process applications — directly comparable to Hydro-Pac's FC-SERIES liquid pumps in pressure class and use cases like pressure testing and isostatic pressing.
• Advanced Compression Technologies (ACT): ACT designs and manufactures oil-free, non-lubricated reciprocating compressors for hydrogen, helium, and specialty gases, mirroring Hydro-Pac's contamination-sensitive value proposition in fueling, semiconductor, and industrial gas applications.
• PDC Machines (Chart Industries subsidiary): PDC Machines designs and manufactures diaphragm compressors for high-pressure hydrogen, helium, and specialty gas applications — directly competing with Hydro-Pac's LX-SERIES and FLEXI-POWER compressor lines in fueling, R&D, and industrial gas markets. Now part of Chart Industries, giving it greater scale and a broader cryogenic/hydrogen portfolio.
