CTD型深井筒袋磁力泵是我公司针对安装空间受限和低汽蚀余量工况研制开发的一种立式悬吊式双层壳体磁力驱动泵，是一种深井灌装式化工工艺用泵，该型泵参照美国石油学会API685标准设计，具有全密封、无泄漏、无污染、效率高、安全可靠、使用寿命长等特点，适用于输送各种易燃易爆的、污染的、易气化的、高温、低温、腐蚀性的液体，主要用于炼厂、石油化工、低温工程、管线调压或海上平台、能源工业冷凝液抽取等。

CTD型泵通过内外磁转子进行耦合传动，外磁转子与电机直联，隔离套将内磁转子密封在泵腔内，运用磁力驱动技术实现全密封，从根本上解决了易燃易爆、有毒有害物料的输送难题。

CTD vertical multistage cylinder-bag magnetic pump is a vertical suspended 2-layer housing magnetic drive pump developed by our company for limited installation space and low net positive suction head operating conditions. It is a type of deep well grouted installation chemical engineering process pump, designed by referencing API685 standards. It features full sealing, no leakage, no pollution, high efficiency, high safety and reliability, and long service life, etc. It is suitable for the transfer of various types of inflammable, explosive, contaminating, easily gasifying, high temperature, low temperature, and corrosive liquids. It is mainly applied in refinery, petrochemical engineering, low temperature engineering, pipeline pressure regulation, and suction of condensate for offshore platform and energy industry.

CTD pump applies inner and outer magnetic rotors to provide coupled drive. The outer magnetic rotor is directly connected to the motor, the isolation sleeve seals the inner magnetic rotor inside the pump cavity, and the magnetic drive technology is used to realize full sealing, which essentially resolves the challenging situation with pumping the feed containing inflammable, explosive, toxic, and harmful substances.

1.CTD型泵为立式筒袋泵，多级径向剖分式结构。

2.轴向力由平衡盘、平衡鼓平衡，或由推力轴承及磁悬浮机构承受。

3.外壳承受入口压力，外壳的长度及泵的深度取决于泵的扬程和装置汽蚀余量的要求。

4.该泵也可以作为多级液下泵和槽罐泵以及多级管道泵使用。泵可以直接安装在介质池中或容器上。

5.内置滑动轴承为流体动力轴承，运行平稳、易维护更换。

6.泵的吸入口和排出口的位置在安装底座的上部，吸入口和排出口一般互成180°布置。

7.泵上设有方便维修的外壳排液置换管和气相平衡接口。

8.泵芯采用可分段、便拆式结构，使泵芯从外壳内拔出时，可从上端分段拆下，也可分段完成装配至外壳体内，不会因为一般的厂房高度影响到泵的拆卸和维修。

9.驱动机可以采用与泵直联或通过联轴器联接的形式。
