During years of development, GNLW series decanter centrifuges now has put into market the 5th generation centrifuge models, GNLW454ET is one of them. Recently, GN has provided to a wastewater treatment project 2 sets of GNLW454ET-VFD decanter centrifuges to an oversea company.

Here are more information about the centrifuges:

1, the material to be treated: the client plans to use the big bowl centrifuge GNLW454ET-VFD for the municipal sewage treatment. The sewage’s solid content is 2-3% and the requested treating capacity is 30 to 40 cubic meters per hour.

2. GNLW454ET-VFD is equipped with 2 motors, a main motor and an auxiliary motor. The main is 45KW, and the auxiliary motor is 15kw.

3. Same as other GN decanter centrifuge models, GNLW454ET-VFD is made of quite high quality material, for example, the centrifuge bowl is made of s2205, and the scroll is made of SS2205, too. Its collection box is made of SS304 while the base is made of carbon steel.

4. The centrifuge is equipped by wear protection methods, for example, there are sleeves at the material distribution ports of the scroll. And at the fluids discharge port, there are sleeves made of hard alloy, too. There are also protections for the ribs inside the centrifuge bowl and scrapers outside. The scroll blades are protected with tungsten carbide tiles.

5. In order to monitor the operation, there are vibration sensors and temperature sensors used on centrifuge.

GNLW centrifuges are applied to many industries besides the waste water treatment, such as oil and gas solids control, drilling waste management, oily sludge separation, food and beverage industry and etc. And GN makes decanter centrifuges with different sizes from 9 inch diameter bowl to 30 inch huge bowl ones.
