Hepu

HEPU: Germany's Cooling System Authority Since 1958

HEPU is one of Europe's most respected names in automotive cooling and timing system components. Founded in 1958 in Kalletal-Hohenhausen, Germany, the brand's very name traces back to its origins: HEinz Pollmann, Ufffeln — the founder's initials and hometown. What began as a focused water pump manufacturer has grown, across nearly seven decades, into a full cooling system solutions provider trusted by workshops and distributors on every continent.

HEPU Engine Water Pumps remain the heart of the brand. Each pump is built to OE-grade tolerances, featuring high-quality cast aluminium housings, sintered-metal pulleys for optimum power transfer, and advanced SIC mechanical seal technology with carbon and ceramic rings to ensure leak-tightness over the long term. Every water pump undergoes pressure and leakage testing before leaving the facility — a standard that has earned HEPU recognition as the leading German water pump manufacturer in the independent aftermarket.

HEPU's Engine Timing Belt Kits represent the natural evolution of that water pump expertise. Because timing belt service almost always coincides with water pump replacement, HEPU developed comprehensive kits that bundle both components — along with tensioners, idler pulleys, and all necessary seals — into a single, coherent repair solution. With over 600 kit references spanning both belt and chain systems, the lineup covers an exceptionally wide range of vehicles, from popular European marques like Audi, BMW, Volkswagen, and Mercedes-Benz to Asian and American applications.

For technicians who need individual components, Water Pump & Components are available separately, making it straightforward to source exactly what a specific repair demands without compromising on quality. HEPU's manufacturing process operates under a quality management system certified to DIN EN ISO 9001:2015, and production decisions — including quality standards and accountability — remain in Germany.

HEPU's commitment to complete cooling system service extends to fluids. Their Engine Coolant and Antifreeze formulations are engineered to complement their hardware, protecting modern aluminum-intensive engines from corrosion, overheating, and freezing. Rounding out the thermal management portfolio, HVAC Heater Control Valves address another critical node in the engine cooling circuit, helping regulate coolant flow to the cabin heater core — an often-overlooked component whose failure can affect both passenger comfort and engine temperature stability.

Whether you're servicing a high-mileage daily driver or maintaining a European performance vehicle, HEPU delivers the engineering precision and product breadth of a manufacturer that has spent more than 65 years doing one thing exceptionally well: keeping engines cool.
