Water Pump WBK 12863021

Description

The WBK 12863021 water pump is a high-quality component of the internal combustion engine cooling system. Its main function is to ensure continuous circulation of coolant, which absorbs heat from the engine and directs it to the radiator. This allows the engine to maintain optimal operating temperature and prevents overheating, extending service life and reliability. Made of durable, corrosion-resistant materials, the pump offers quiet operation, high efficiency, and long-lasting durability even under heavy-duty conditions.

Technical Data

  • Type: water pump
  • Part number: 12863021
  • Material: cast iron/metal resistant to corrosion
  • Average flow rate: approx. 80–120 l/min
  • Operating temperature range: -40°C to +120°C
  • System working pressure: up to 2 bar
  • Mounting: factory-fitted for engine block housing
  • Seal: high-temperature, multi-layer
  • Bearings: reinforced ball bearings, pre-lubricated for lifetime use

Application

The WBK 12863021 water pump is designed for use in combustion engines of construction, agricultural and industrial machinery. It can be used in excavators, loaders, bulldozers and heavy transport equipment. Its role is to stabilize engine temperature even under heavy loads, making it a key element of the cooling system.

Properties

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
