German we-er pump we-er model we-er price

we-er pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquid or increase its pressure. It consists of two gears, a pump body, and front and rear covers, forming two enclosed spaces. When the gears rotate, the volume on the disengaging side increases from small to large, creating a vacuum that draws in the liquid. The volume on the meshing side decreases from large to small, forcing the liquid into the pipeline. The suction chamber and discharge chamber are separated by the meshing line of the two gears. The pressure at the discharge port of the gear pump depends entirely on the resistance at the pump outlet. we-er pump work
