What Hammelmann does

Hammelmann GmbH is a German manufacturer of industrial high-pressure pumps and water jet technology systems, founded in 1949 by Paul Hammelmann and headquartered in Oelde, Germany. The company operates as a wholly-owned subsidiary of the publicly listed Italian industrial conglomerate Interpump Group. Its core technology spans operating pressures from 20 to 4,000 bar, with volume flows up to 3,000 liters and drive power up to 1,100 kW, supported by proprietary drive systems, configurable water hydraulics (valves, rotary connections, safety modules), and an in-house Technology Center that performs 200+ application tests per year using CFD simulation.

The product portfolio is organized around four lines: (1) high-pressure pumps and units, including the HDP 680 ten-cylinder pump and 3,600 bar capability; (2) water jet technology systems (AQUABLAST surface cleaners, AQUAMAT/AQUAREX tank cleaning devices, DOCKMASTER/DOCKBOY/DOCKMATE ship cleaning systems, JETMASTER high-pressure robots, SPIDERJET cleaning vehicles, TURBOJET turbo nozzles, MASTERJET rotor jets, PIPEMASTER rotating devices); (3) water hydraulics accessories; and (4) Hammelmann Process Technology pumps for chemical injection, LDPE dosing, fatty alcohol processing, descaling, and fiber meshing. The company also offers rental units, demonstration services, training, and same-day spare parts dispatch, supported by the free Water Jetting Calculator app available in 26 languages.

Hammelmann serves industrial manufacturing, industrial cleaning services, chemical/process, metal fabrication, maritime/offshore, food processing, and construction/municipal customers across seven wholly-owned subsidiaries (USA, China, Australia, Spain, France, Switzerland, Türkiye) and 40+ agency representatives, with 10,000+ pumps in operation globally. The company holds ISO 9001, 14001, 45001, and 50001 certifications alongside ASME and SIR pressure-equipment accreditations, and has been recognized with the German Environmental Award (DOCKMASTER) and German Safety At Work Prize (ERGOBLAST gun). Revenue is generated through direct enterprise field sales, hardware, spare parts, rental, professional services, and training, with quotation-based pricing across a multi-decade installed base.

• Jetstream Systems: Jetstream Systems supplies high-pressure water pumps, nozzles, tools, and automated equipment for tube cleaning and industrial surface preparation. Its solutions overlap Hammelmann's pressure levels, applications, and B2B sales motion.
• Flow Waterjet: Flow Waterjet provides ultra-high-pressure intensifier pumps and complete water-jet systems for cutting, cleaning, and surface preparation. Its intensifier technology and turnkey system offering make it a close product and engineering peer.
• URACA: URACA manufactures high-pressure plunger pumps and systems for industrial cleaning, hydrojetting, and process applications. Its product scope, engineering intensity, and direct industrial customer base closely overlap Hammelmann's core business.
• KAMAT: KAMAT develops high-pressure plunger pumps and engineered systems for industrial cleaning, desalination, oil and gas, and other demanding applications. Its pressure range, customization model, and target customers are closely comparable to Hammelmann.
• NLB Corporation: NLB manufactures ultra-high-pressure water-jetting pumps, tools, and automated systems for industrial cleaning, surface preparation, and pipe and tube cleaning. It is highly comparable to Hammelmann's cleaning and water-jet technology business.
• Speck Pumpen: Speck Pumpen manufactures high-pressure plunger pumps and systems for water-jet, industrial process, cleaning, and original-equipment applications. Its pump-centric portfolio and customized equipment model compare directly with Hammelmann.

Emerging players

• OMAX: OMAX manufactures integrated abrasive water-jet cutting systems for industrial fabrication. It overlaps Hammelmann in high-pressure water-jet technology and industrial customers, although OMAX is more focused on complete cutting machinery than standalone pumps.

Broad incumbents

• Sulzer: Sulzer manufactures engineered industrial pumps and process-fluid equipment, with substantial aftermarket and service operations. It is comparable to Hammelmann's process-pump and fluid-handling activities, though Sulzer serves a much broader set of pump categories and industries.
• Kärcher: Kärcher is a global cleaning-equipment incumbent with industrial pressure-washers, water-jet systems, and related service capabilities. Its broader portfolio overlaps Hammelmann's industrial cleaning equipment and global customer access, but it is not focused exclusively on ultra-high-pressure systems.
