该泵是在循环水多用真空泵的基础上，根据实验室面积较小这一特点，参照日本台式泵，一次性成型外壳，缩小体积改进而成，具有体积小，重量轻，外型美观等特点，分双表双抽头,四表四抽头等多种形式，双面相同的多用真空泵，即便于教师直观演示，学生亦可在任意一面开机、关机。
(1)本机采用双抽头，装有两个真空表,可单独或并联使用。
(2)新改进防腐四抽头，装有四个真◣空表,可单独或并联使用。
(3)主机采用不锈钢机芯或¤防腐材质机芯。
(4)耐腐蚀、无污染、噪音低、移动方便，还可根据用户需要加装真空调节阀。
（5）可同时有四名学生进行化学实验，缩小实验空间。

The pump is made on the basis of circulating water multi purpose vacuum pump, and in view of the small space of the lab, and with reference to the Japan -made bench-type pump, made with reduced size and improvement, and adopting one-shot forming, it has the feature of small size, light weight and beautiful appearance and so on, it has double-size-double- tap air extracting, 4-size-4-tap , identical dual size multi purpose vacuum pump. While the teacher is demonstrating, students can also turning on or off the machine on any size of it.
1. It adopts dual taps, can be used independently or in parallel combination, with 2 vacuum meters.
2. Newly improved anticorrosion four taps can be used independently or in parallel combination, with 4 vacuum meters.
3. The host machine has two models; one is made with stainless steel module and the other with anticorrosion materials.
4. It is corrosion resistant, pollution free and with low noise, and easy to move, also, vacuum-adjusting valve can be added according to the needs of customers.
5. Four students can conduct chemical experiments simultaneously, reducing experiment space.
