PARKER齿轮泵现货公司总销售齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力*取决于泵出口处阻力的大小。
PARKER齿轮泵现货公司总销售齿轮泵工作时，主动轮随电动机一起旋转并带动从动轮跟着旋转。当吸入室一侧的啮合齿逐渐分开时，吸入室容积增大，压力降低，便将吸人管中的液体吸入泵内；吸入液体分两路在齿槽内被齿轮推送到排出室。液体进入排出室后，由于两个齿轮的轮齿不断啮合，使液体受挤压而从排出室进入排出管中。主动齿轮和从动齿轮不停地旋转，泵就能连续不断地吸入和排出液体。
齿轮泵除具有自吸能力、流量与排出压力无关等特点外，泵壳上无吸入阀和排出阀，具有结构简单，流量均匀、工作可靠等特性，但效率低、噪音和振动大、易磨损，主要用来输送无腐蚀性、无固体颗粒并且具有润滑能力的各种油类，温度一般不超过70 ℃，例如润滑油、食用植物油等。一般流量范围为0.045～30ms/h，压力范围为0.7—20MPa，工作转速为1200—4000r/min。
