Free USPS PRIORITY MAIL Shipping Graf Water Pump The Graf Water Pump contains no remanufactured parts and is produced using an optimized all metal impeller design to assist in cooling under high RPM, and performance demands. Selection of raw materials, reliability of machinery and production processes, stringent controls throughout the production process, from melting to fitting, as well as reliability tests performed using equipment able to determine true performance, go to ensure this product is a real guarantee of safety and long life. The Graf water pump is centrifugal in type and comprises a bladed rotor linked by means of a shaft (which rotates on bearings housed in a support) to the drive gear; the seal between the pump and the motor block is guaranteed by a gasket, while the inside of the pump is guaranteed by a mechanical seal. Component parts: Impeller: supplies the fluid with the necessary energy to cover the entire cooling circuit. Mechanical seal: ensures fluid seal inside the pump. Bearing: transmits movement to the impeller and supports any ventilation parts. Entrainment part: for transmitting movement to the bearing. Pump body: supports the basic pump component parts and conveys the coolant in the motor block.
