Product Description:

ALDG multistage pipeline centrifugal pumps are newly developed products designed and manufactured to the standard of JB/TQ6435-92, destined to meet the users’ requirements and relative fire control standard on the basis of the advanced pump models at home.
This pump model takes a vertical segmental structure with stainless casing outside, and the inlet and outlet of pump are located on the same horizontal line and are of the same diameters, so that it can be mounted, just like a valve, in pipeline. Combined with the advantage of high pressure of multistage pump, the small occupation space of vertical pump, the easy installation of pipeline pump, and the use of advanced hydraulic model to feature high efficiency, energy conservation, smooth operation etc., as well as wear-resistant mechanical seal to feature leak-tightness and long service life.
To better meet users’ requirements, we have developed the model of ALDGS of which the outlet is located at the upper part, and the outlet and inlet can be easily mounted to the angles of 0℃, 90℃ and 180℃.
For make operation safer and more dependable, we have developed detachable structure. Besides all the advantages of ALDG and ALDGS, it makes the replacement of mechanical seal and other wearing parts much easier, faster and labor-saving, making the operation and maintenance more reliable.

Conditions:

1、 This type of pumps is used to deliver clean water or liquids similar to clean water in physical and chemical properties;
　　2、 Liquid temperature:-15℃～+120℃;
　　3、 Working pressure: Maximum working pressure<2.5MPa, i.e. system pressure = inlet pressure + the working pressure under valve closed <2.5MPa;
　　4、 Ambient temperature shall be lower than 40℃, and relative humidity lower than 95％;
　　5、 To deliver corrosive medium and hot liquid, please specify when placing an order for our convenience to use special material.

Application:

This type of pumps is suitable for the circulation and pressurization of cold and hot clean water in high-pressure operation system, water supply under parallel operation of several pumps in high-rise constructions, water supply for fire control and boilers, cooling water system, and the delivery of various washing liquors.
