GN Solids Control is a leading manufacturer of decanter centrifuges. And our supplier from Switzerland is the leading brand in centrifugal hydraulic driving systems. GN and our Swiss supplier have been working together to develop the full hydraulic drive centrifuge for international customers to meet the highest standards.
The hydraulic bowl and displacement drive system drive both the conveyor and the bowl of a decanter centrifuge from the hydraulic pump unit via two hydraulic oil circuits.
The advantage of the fully hydraulic drive centrifuge is its use in high-temperature environments for heavy sludge with a flexible bowl and differential speed. The compact single skid design makes mounting easy.

PRINCIPLE OF HYDRAULIC DRIVE SYSTEM- FHD PRINCIPLE
The fully hydraulic system consists of A the hydraulic pump unit, B the bowl drive hydraulic motor and C the travel drive.
Hydraulic pump unit A feeds hydraulic oil to scroll drive C and bowl drive B by two separate and individually independent operating circuits
An electric motor A1 drives the combined pumps A2 and A3. Each operating circuit is equipped with its own hydraulic pump and controls. The pump unit contains all adjustment devices and safety valves as well as pressure gauges.
With this system, the rotation speed of the bowl, as well as the differential speed of the scroll, can be manually adjusted independently of each other, continuously and infinitely variable during the operation of the centrifuge.
