LQG type three-screw asphalt pump

Features

The salient features of the LQG three-screw asphalt pump are its simple structure, low pressure pulsation, stable flow, reliable work balance, high rotation speed, low noise, high efficiency, long life, and self-priming capability.

Product Usage

The three-screw pump is suitable for the transportation of lubricating oils and lubricious liquids of fuel oils, lubricating oils, hydraulic oils, crude oil, bitumen and other similar oils. Lubricating pumps in the industrial sector, hydraulic pumps in the hydraulic system, conveying and booster pumps in the fuel system, and conveying and refueling pumps in the oil system. The distinctive feature of the LQG three-screw asphalt pump is its simple structure. , Low pressure pulsation, stable flow, reliable working balance, high rotation speed, low noise, high efficiency, long life, self-priming ability.
