HDD VSM 300 Shale Shaker

The BRANDT™ VSM 300 shale shaker delivers a dramatic increase in capacity through unique vibratory motion and screen deck layouts


As the world's first balanced, elliptical-motion, low-profile cascade shaker, VSM 300’s use of integral secondary drying technology demonstrates our commitment to delivering cost-effective, environmentally responsible solutions for all industrial, construction and microtunneling projects. The VSM 300 is an extremely simple machine to operate, maintenance is minimal, and screen changing is carried out in 2 to 3 minutes by a single technician

Supplied in modular form, the VSM 300 can be assembled on-site to produce multiple units, thereby reducing installation time and costs. The proven shallow header tank system provides equal flow distribution across the shakers, even when multiple units are installed.


  • Balanced elliptical motion
  • Available with CONSTANT-G CONTROLTM (CGC), a patented technology that maintains an optimal G-force rating during variable liquid/solids loading conditions
  • CGC improves flow capacity, provides constant solids conveyance and finer screening capacity
  • Integrated scalping deck (three screens)
  • Reduces the need for (and subsequent costs and weight of) upstream scalping shakers
  • 20.5 ft2 (1.9 m2) of screening area 
  • Primary deck angled at 7° incline (four screens)
  • Excellent solids conveyance and liquid/solids separation, even when troublesome drilling conditions arise
  • Keeps the fluid pool volume small, which helps to increase screen life
  • 26.3 ft2 (2.4 m2) of screening area
  • Integrated drying deck (two screens)
  • Reduced mud losses by creating a dry solids discharge
  • 3 ft2 (0.3m2) of screening area
  • Pneumoseal clamping system
  • Screens are properly secured to the basket for quick and easy screen changes
  • Variable frequency drive (VFD) control
  • Soft-starting fingertip adjustments of motor speed and matching of G-force to operating conditions
