Dayco releases high-efficiency aftermarket water pumps

Dayco, a leading engine products and drive systems supplier for the automotive, industrial and aftermarket industries is set to launch its first stand-alone mechanical water pump programme in the UK and Ireland this March. The initial range provides coverage for 90 per cent of the vehicle parc, which equates to approximately 27 million vehicles.

Dayco Water Pump copyDayco is a technical leader in the design and manufacture of essential engine products and low friction power transmission systems, which it supplies to its vehicle manufacturer partners to save fuel and reduce emissions produced by their engines.

As the water pump is now integral to many primary drive systems, the on-going requirement to achieve a low friction return from the primary drive system also influences the design of the water pump, which is why the highly-efficient pumps within the programme fit so comfortably within Dayco’s existing aftermarket product portfolio.

Dayco has a global reputation as a top quality OE (original equipment) manufacturer and supplier, and the new Dayco water pumps are naturally manufactured to the same high standards as the many existing components the company manufactures and distributes globally.

 “With this introduction, we provide our customers with a high-calibre component that carries the same hallmark for quality as the existing Dayco product range, but which also allows them to cater for a different although complementary product group,” said Massimo Falco, Product Management and Engineering Manager for Dayco in Europe.

Each Dayco water pump features the latest technology, including low friction seals, which are arguably the water pump’s most critical component because the seal must not only prevent coolant leakage, but also provide a long service life. As a result, the highest quality materials have been used in the seal manufacturing process.

Additional design features include coolant-resistant, long service life grease for the bearings and pump specific impellers that are optimized for each individual application and designed to ensure efficient coolant flow throughout the engine and prevent cavitation within the coolant. Impeller design is extremely complex and requires both high-tech software and comprehensive real world testing to ensure the performance of the finished product.

Finally, the main water pump bodies are designed to support external loads from the associated components in the drive belt system, as well as engine vibrations and thermal movement, while remaining perfectly watertight in all conditions.
