The stainless steel gear pump is a positive displacement SS gear oil pump. Its structure is composed of a pair of gears and pump casings that mesh with each other. The discharge volume of the stainless steel gear pump is the same for each revolution. With the uninterrupted rotation of the drive shaft, the SUS gear pump continuously discharges fluid. The flow rate of a stainless steel gear pump is directly related to the speed of the pump. To obtain a large flow rate, the speed of the stainless steel gear pump must be increased. The speed of the stainless steel gear pump is limited, which mainly depends on the process fluid. If it is transporting oil, the stainless steel gear pump can rotate at a very high speed. But when the fluid is a high-viscosity polymer medium, the speed of the stainless steel gear pump will decrease.
