Agitation Resource, Inc. Product Description

ARIP Group - Portable Mixers

The ARIP group of portable agitators represents an extensive selection of heavy duty, yet light in weight, custom designed agitators. The units are engineered to provide excellent mixing results in smaller vessels regardless of shape. Agitators in this group all use standard commercially available components, which have been selected with great care, to meet our demanding design criteria. The extensive available options allow for the creation of a precise solution for every agitation application. ARIP group agitators are provided in either clamp or cup mounted versions. Optimum performance and cost containment is provided by offering both direct drive or gear reduced versions.


ARIP portables employ a heavy duty, in-line, and helical gear reducer. The gear reducers are all energy efficient with power transmission efficiency of 95-98% depending on the number of gears required. The high efficiency translates into electrical power savings as well as lower frictional heating which helps to lengthen the service life of the unit.

Gears and case

  • Gears are manufactured to the ANSI/AGMA 2000-888
  • Gears are CNC machined and carburized to 58 – 62Rc
  • Cases are manufactured from SAE Class 30 cast iron; heat treated and stress relieved
  • Gears and bearings are splash lubricated
  • Output shafts provided with double lip seals. A true dry-well option is available
  • Lubrication options include mineral or synthetic oils as well as FDA approved lubricants
  • Output speeds can range from 10 rpm to 420 rpm
  • Minimum AGNA rated service factor of 2.0
  • Bearings have a rated L-10 life of 100,000 hrs


Electric motors used to drive the ARIP agitators range from Fractional hp to 3 hp. Units driven by pneumatic motors range from 1.5-4 horsepower. Electric motors are available in all of the voltage and frequency configurations necessary to satisfy the diverse sources of power. Motors satisfy NEMA /IEC standards. Mounting for motors may be integral or C-face. C-face motors are connected to the reducer with an adapter and flexible coupling. Integral motors are supplied with a pinion gear for direct gear engagement. Depending on service conditions, motors may be tefc, explosion proof, wash down duty, chemical duty, severe duty or inverter duty. All NEMA standards for insulation and service factors are satisfied Class B insulation is standard; however, motors with class F and H insulation are also available. Bearings are sealed with grease, which is adequate for the life of the motor.


Shafts employed in the ARIP group range from .750” to 1.250” in diameter. ARIP shafts are designed to withstand all of the torsion and bending forces created by the agitator. In addition, the agitator housing is provided with an out-board sealed bearing for additional support. In front of the bearing a lip seal is provided for enhanced corrosion protection for the bearing and compression coupling. The material of construction is determined by the process requirements. A majority of applications are resolved with the use of 304 or 316 stainless steel or their low carbon analogues. However; shafts constructed of Titanium. High Nickel alloys or Carbon Steel with or without a protective coating are also available. The shaft is secured to the driving element by the use of a precision compression coupling. An ample slotted opening in the side of the housing allows for access to the coupling.


The housing and clamp assembly, employed with the ARIP portables, is constructed of high strength cast Aluminum. The housing is precision machined to ensure the precise alignment of the output shaft of the motor or gear reducer with the centerline of the out-board bearing. This configuration allows for smooth, vibration free operation. The clamp assembly is extra strong and is provided with a stainless steel lock down rod, to which is attached a toggle pad and a tightening handle. A lock nut is also provided to ensure that the clamping elements will always remain tight to the vessel sidewall.
