Centrifuges are used to process unweighted and weighted oil-based drilling fluids(muds). The LW355 series centrifuge uses high G-forces to separate fine solids from liquid .Four models are available :
LW355x1257 FS
LW355x1257 VFD
LW355x1422FS
LW355x1422 VFD
The 355 series centrifuge has a high capacity 355mm diameter and 1257mm long stainless steel bowl and conveyor assembly. The available power for the main drive (30KW) and back drive (7.5KW),When speed up to 2800RPM to 3200RPM generating centrifugal forces up to 2035G’S
Features & Benefits :
  1. Patent cooperate and design with many well-known universities for customer’s higher request ;
  2. Bowl Cylindrical , spiral and main spare parts made from duplex Stainless Steel or anti-corrosion resistant stainless steel owned high speed and big G-force;
  3. High  configured models can reach stepless adjustable with bowl and spiral;
  4. The surface of spiral propeller coated with alloy or inlayed hard alloy;
  5. Patent design flow distribution port for easy adjustable and suiting for different operating condition;
  6. Pressurized EX Proof VFD control cabinet with PLC controlled;
  7. Genuine SKF / NSK  bearing for longer and reliable operation;
  8. Cycloidal gear , planetary gear and hydraulic differential for three different option ,which owned full range differential regulation suiting for different torque of solids transmission;
  9. Muti-safety protection : motor overload protection, bearing temperature monitoring ,torque protection of screw pushing.
