3QGB保温沥青泵是一种容积式泵，显著的优点是结构简单、体积小、允许高转速工作平稳可靠、压力脉动小、流量稳定、噪音低、效率高。正是利用螺杆啮合原理，依靠旋转的螺杆在泵套内相互啮合，把被输送的介质封闭在啮合腔内，沿螺杆轴向连续匀速地推至排出口，为系统提供稳定的压力。
3QGB保温沥青泵用于输送各种无腐蚀性油类及类似油的液体，输送液体的粘度范围一般为3.0-760mm2/s(1.2-100oE)。高粘度介质可通过加温降粘后输送，其温度一般不超过350℃。3QGB保温沥青泵采用铸钢制成，有保温和不带保温两种，建议高粘度介质采用保温结构的螺杆泵。
3QGB保温沥青泵具有以下特点：
定子与转子接触的螺旋封线将收入腔与排出腔完全分开，使泵具有阀门的隔断作用。
可实现液、气、固体的多相混输。
泵内流体流动时容积不发生变化，没有瑞流搅动和脉。
弹性定子形成的容积腔能有效地降低输送含固体颗粒介质时的磨耗。
输入介地粘度可达50000Mpa?s含固量可达50%。
流量与转速正比，借助调速器可实现量的自动调节。
3QGB保温沥青泵用途：
在供热设备中用做燃油喷油，燃油供应和输送泵。
在机械工业中用做液压，润滑和遥控马达泵。
在化学石油化工和食品工业中用做装载，输送和供液泵。
在船舶上用做输送、增压、燃油喷射和润滑油泵以及船用液压装置泵。
