gd管道泵，立式单级单吸泵，离心式管道增压泵，清水循环泵，直联式增压泵
管道离心泵直接安装在管线上,对所输送的介质进行加压,也可以如普通离心泵一样用于抽吸液体。本厂生产的管道离心泵体积小、重量轻、结构紧凑。可单台或多台串联，可卧式或立式安装使用。法兰尺寸符合国标标准（iso2084-1974）。
gd为普通型管道泵，供输送80℃以下的清水或物理化学性质类似清水的介质。主要用于制冷、空调、消防和一般供水系统。
gf为耐腐蚀型管道泵，根据所输送介质对泵的腐蚀情况，针对性选择触液体部件的耐腐蚀合金。适用于石油、化工、医药、食品等行业中，输送有腐蚀性、粘度类似水的介质或卫生介质。
gr为热水型管道泵，供输送120℃以下的热水，用于采暖和热力系统热水循环，或余热利用系统热水的输送。
型号说明：
in-line centrifugal pump is installed on the pipeline, exerting pressure on the liquid to be conveyed, as well as normal centrifugal pump to lift water. the in-line centrifugal pump manufactured in our factory has a small body, light weight and compact structure. thus it can be utilized singly or jointly, and be installed in horizontal or vertical manner. flange sizes comply with iso 2084-1974.
in-line centrifugal pump model gd is used to convey pure water under 80℃ or other liquids with similar physical and chemical characteristics, maily for refrigeration, air-conditioning, fire-fighting and the normal water supply system.
model gf is corrosion-resisting. a variety of corrosion-resisting alloies could be selected from according to the corrosion of liquids to the pump. it is utilizable for the conveyance of corrosive liquids which adhesion as water, or sanitation liquids in petro-chemical, pharmaceutical and food-processing industry.
model gr is for the conveyance of hot water under 120℃, for heating or heating power system hot water circulation, or the conveyance of hot water of remaining heat utility system.
gd、gr model executive standard: gb/t5657-1995；
gf model executive standard: gb/t5656-1994。
