The water pump is a central component of the cooling system, which is why its failure can have serious consequences, such as expensive repairs and unexpected downtime. This makes it all the more important to ensure high quality when selecting a spare part. DT Spare Parts has the right offer for this.

Water pumps ensure that coolant is circulated in the cooling circuit as required, thus preventing the engine from overheating. They are driven by the crankshaft via a V-belt that runs on a pulley or vibration damper. The service life of water pumps depends to a large extent on the quality of the coolant, the condition and reliability of the neighbouring units, as well as professional installation.

A conventional water pump is driven by a pulley that is rigidly connected to the drive shaft. The water pumps with electromagnetic clutch from DT Spare Parts allow a two-stage separation of the belt pulley and drive shaft, so that demand-orientated circulation of the coolant is possible depending on the operating status. By reducing the delivery rate in the partial load range, the required drive energy is reduced and fuel consumption is lowered accordingly.

The impellers of DT Spare Parts water pumps are optimally designed to enable a high flow rate of the coolant and thus achieve a high degree of efficiency.

The earlier metal impellers have been replaced by plastic impellers (PPS, X-TEL) in modern applications. The lower weight of these impellers prevents the formation of air pockets in liquids (so-called cavitation) and minimises the bearing load.

First-class quality and durability for your vehicles

All products fulfil the highest quality standards thanks to the specially developed Diesel Technic Quality System (DTQS), which is a core value of the company. It guarantees a consistently high level of quality and ensures that the products are continuously optimised (continuous improvement process = CIP).

The DT Spare Parts range ncludes more than 400 items for the water pump product group, including seals, impellers, repair kits and accessories.

To ensure the best quality and safety, the products are tested on our own water pump test bench. Leak and performance tests are carried out, as well as volume flow (l/min.), speed (r/min.) and pressure (bar). DT Spare Parts tests its water pumps under the same conditions as OE.

Customers benefit from a 24-month brand guarantee, 30 application-oriented product catalogues (digital and printed), extensive online services and a special loyalty programme with an exclusive Premium Shop. Workshop professionals also receive support from the Parts Specialists in the form of videos and fitting instructions.

If you have any technical questions about Diesel Technic products and services, the Parts Specialists will be happy to provide the right support via their HelpDesk: helpdesk.parts-specialists.com.
