CDL-multi-stage pipeline centrifugal pump is a unit based on excellent pump at home and abroad with the user's requirements and fire-related standards, and in accordance with the JB / TQ6435-92 standard design and manufacture of a new generation of products.

This type of pump uses the vertical segment plus stainless steel shell structure, making the import and export of pumps in the same horizontal line and the same caliber, the same as the valve can be installed in the pipeline, it also focused on the multi-stage pump high pressure, legislation Because of the excellent hydraulic model, it also has the advantages of high efficiency and energy saving, stable operation, etc., and the shaft seal adopts the wear-resistant mechanical seal, no leakage and long service life .

In order to better meet the requirements of users, our company has also developed the GDLS with the water outlet located in the upper part. The import and export of the GDLS can be installed in different relative positions (0 °, 90 °, 180 °) and is extremely convenient to use.

In order to make users more safe and reliable use of the pump, the unit has specially developed a removable structure, it has all the advantages of GDL, GDLS, but also for you to replace the mechanical seals and other wearing parts to provide a more convenient , Fast, labor-saving way to make this pump more worry-free operation and maintenance.

Application range

This type of pump is mainly suitable for circulation and pressurization of hot and cold water in high-pressure operation system, parallel supply of multiple pumps in high-rise buildings, fire fighting, boiler feedwater and cooling water system and various flushing fluid delivery.

Working conditions

1. This pump can transport clean water or physical and chemical properties similar to the liquid water;

2. Liquid temperature: -15 ℃ ~ +120 ℃;

3. Working pressure: The maximum working pressure <2.5MPa, the system pressure = inlet pressure + pressure when closing the valve

<2.5MPa; 4. Ambient temperature should be below 40 ℃, relative humidity not exceeding 95%;

5. Conveyor containing corrosive media and hot liquids, please put forward when ordering, so that the use of special materials to meet the requirements.

Application

It applies to delivering non-corrosive lubricating-oil or equivalent liquid without solid particles and fibres at temperature below 300℃ and with the viscosity of 5×10^-6-1.5×10^-3 m²/s(5-1500cst).Reducing the speed,the pump can delivery the liquid that the viscosity can be up to 5×10⁴cst.

Application scope

It can give performance as transfer pump or booster pump in oil delivery system. It can be also applied as fuel pump for delivery system,pressurization and injection in fuel supply system and in all industry fields as lubricating pump.
