Gear pump with the main difference between the oil pump

The main difference between Gear Pump and Roots Oil Pump lies in the following aspects: First, the number of gear pump revolutions is higher than that of Roots Oil Pump. Conventional gear pump turned in 960r / min - 1450r / min, Roots pump revolutions in the 50r / min - 500r / min. Second, the gear pump belongs to the external gear pump, Roots pump belongs to the external rotor pump. Gear pump generally adopts involute helical gear point contact arc gear; Roots pump use 8-shaped rotor or plum-type rotor gear. Third, the transmission viscosity of the gear pump is lower than that of the Roots pump. Gear pump with Roots pump different number of revolutions, gear structure is different. Therefore, under normal circumstances, the viscosity of the medium delivered by Roots can be higher than the gear pump. Fourth, the gear pump is more sensitive to impurities, Roots pump is not sensitive. Because gear pump structure, material and Roots pump is different, Roots pump gear module, gear pump gear modulus is small, so the gear pump is more sensitive to impurities in the medium, and Roots pump is not sensitive, it is recommended In the delivery of impurities in the material suggest that you choose Roots pump.
