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.

Product Features:
  • All the component parts fitted are pre-tested to evaluate durability, performance and reliability.
  • The bearings undergo a durability test equivalent to nominal lifespan and are then inspected to assess integrity.
  • The mechanical seals are tested in extreme coolant temperature conditions according to predefined cycles.
  • The shape of the impellers is optimized thanks to the use of prototypes on which flow and performance tests are performed.
  • On both the entrainment parts and the bodies, the choice of materials and/or technologies different to original ones is made on the basis of structural and mechanical tests.
  • After assembly all the pumps undergo seal tests on units that reject those with leaks above set limits.

from

$135.99
The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Sensor reports system pressures to the on-board computer, in turn allowing the computer to properly and efficiently control the compressor, fans and system levels. An improperly functioning A/C Pressure Sensor will provide erratic or inaccurate readings to on-board computers severely affecting system performance and function. Without reliable and accurate data from a properly functioning A/C Pressure Sensor, on-board computers are unable to protect the safety of critical components and the system as a whole which can lead to excessive wear and tear on critical components and costly system damage.

Product Features:
  • Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to exceed OE performance and to meet the uncompromising demands of service professionals.
  • Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your A/C Pressure Sensor.
  • All units are helium leak tested on fully automated mass spectrometer equipment before end-of-line testing.
  • All units are tested using automated end-of-line testing equipment that pressurizes the A/C Pressure Sensor and checks full-spectrum functionality and electrical output to ensure each A/C Pressure Sensor meets manufacturing specifications before packaging
