Ideal for Feeding Dry Materials – in a Wide Range of Industries

  • Municipal Water
  • Wastewater Treatment
  • Industrial Process
  • Chemical Process
  • Food Processing

Rugged Construction – Backed by a Two-Year Warranty

The VMF-28 features a rugged, steel frame protected by a corrosion resistant finish. The critical areas – hopper, augers, loading boxes and piping – are all stainless steel.

Heavy Duty Motor & Direct Drive Mechanism – for Reliable Operation

The VMF-28 basic unit employs a direct drive, variable speed, TENV 90 VDC washdown gear motor with a quick change auger assembly. To meet a range of application requirements, standard motors are available from 1/8 HP to 1/4 HP while optional Washguard® and explosion proof motors are available from 1/3 HP to 1 HP.

Choice of Auger Styles – with Feed Rates up to 50 Cubic Feet/Hour

Multiple Auger Styles

Quick change, concentric helical overwind feed screws are available in rugged 304 or 316 stainless steel as either a 0.75″ to 3.25″ diameter solid auger or a 1.5″ to 3.25″ diameter open helix auger.

Gravimetric Feeding – with Integrated “Loss in Weight” System

VMF feeders are available with an integrated scale that allows measurement of dispensed amounts via “loss in weight” providing operators with constant real time assessment of the total mass of additive being used.

Multiple Control Options – for Accurate Feed Rates

Variable Speed and SCADA Programmable Motor Controllers
