Specifications

Product overview
CDLF series vertical multistage centrifugal pump (hereinafter referred to as the pump) is learned at home and abroad advanced technology and the design and manufacture of non vertical multi-stage centrifugal pump, using the standard vertical motor and quick assembling type mechanical seal, the replacement is very convenient. Pump parts are made of stainless steel (304\316) material, can be applied to mildly corrosive media. The product can replace the foreign CR, CRN and other similar products. Products on the market, with its high efficiency and energy saving, reliable quality, the use of a wide range of features, well received by the user's favorite. GDL type multistage centrifugal pump is a new type pump, with obvious energy saving, small occupation area, convenient installation, stable performance characteristics. Coat with 1Cr18Ni9Ti high-quality stainless steel seal with wear resistant mechanical seal, no leakage, long service life. To solve the hydraulic axial force balance, so the pump running smoothly, low noise, installation conditions better than the DL type pump, can be easily installed in any section of the level of the middle line. Can meet the high-rise buildings, deep mining, water supply and drainage and fire facilities, is the vast number of hot and cold water delivery industry general media, physical and chemical properties similar to water the optimal pump type liquid.
Product characteristics
GDL type multistage centrifugal pump is my units in the domestic and foreign excellent pump on the basis of the use of user requirements and fire related standards, and in accordance with the JB/TQ6435-92 standards of design and manufacture of a new generation of products.
This type pump adopts a vertical segment and stainless steel shell structure, the import and export of pumps are positioned on the same horizontal line and the same caliber, can be the same as the valve installed in the pipeline, it also focused on the high pressure multistage pump, vertical pump pipeline pump covers small area and convenient installation, due to the use of excellent hydraulic model, so it is with high efficiency and energy saving, stable operation and the like, and seal with wear resistant mechanical seal, no leakage, long service life.
In order to better meet the requirements of users, the unit also developed a water outlet located in the upper portion of the GDLS type, its import and export to different relative positions (0 °, 90 °, 180 °) installation, use the very convenient.
In order to enable users to more secure, reliable use of this type of pump unit, the special developed a detachable structure, it has all the advantages of GDL, GDLS, more for you to replace the mechanical seal wearing parts with a more convenient, fast, saving way, make this type of pump is more worry-free operation and maintenance
.
Working conditions
The 1 type pump can transport water or similar to the physical chemical properties of liquid water;
The 2 liquid temperature: -15 ℃ ~ +120 ℃;
Working pressure: 3 maximum working pressure of < 2.5MPa, namely the system pressure = entrance pressure + closed valve working pressure < 2.5MPa;
4 ambient temperature should be lower than 40 ℃, relative humidity of not more than 95%;
The 5 conveying corrosive medium and a hot liquid, please order when put forward, so that the use of special materials to meet the use requirements.
