The Sardik’s top entry gear drive mixer provides a more cost effective alternative to parallel helical geared units. The reducers utilize non-proprietary worm gearing, specifically designed for reliability and versatility in high production environments.The compact design of the worm reducer provides a low profile for installation into space-restricted environments. As with all Sardik’s top entry equipment, the N-series utilizes process matched wet ends for optimum agitation solutions.

• A new twist is added in the arrangement of gears. Interchangeability of components is further advanced.
• The number of speed and motor output combinations is substantially increased to 17.
• An impeller having a simple three-bladed axial flow design in one stage has been developed, featuring a high discharge coefficient and a low drag coefficient.
                                                              

Nord^®s reducers are engineered and manufactured specifically to withstand the demanding loads imposed on the drive by most mixing applications. The large bending moment created by the cantilevered mixing shaft and impeller is largely isolated from the gearing by the unique output bearing arrangement. All helical gearing with exceptional load carrying capacity ensures highly efficient and dependable transfer of energy into the process fluid.

• Rugged cast-iron housing-accepts mixing stresses while maintaining accurate gear alignment and resisting corrosion. 
• Convenient C-face motor adapter-this fully registered adapter ensures fast, positive motor alignment, eliminates hassles with V-belts, sheaves and guards, and simplifies installation with a flexible coupling. 
• High-strength helical gearing - all-helical gearing is designed for high efficiency and maximum load carrying capacity with reserve strength rating. All gears are AGMA Quality 10.
  No-leak drywell construction-oil sump is isolated from output shaft to prevent gear lubricants from leaking and contaminating the product being mixed.
• Unique low speed bearing arrangement-High-capacity, spherical-roller,mixer shaft bearing isolates impeller loads from gearing and provides high moment capacity. Tapered roller bearings accept high thrust loads in either direction.
• Re-greasable low speed bearings-upper tapered roller bearing and bottom spherical roller bearing are grease lubricated and field re-greasable for easy maintenance. Lower tapered roller bearing is oil-lubricated
• Simple, positive lubrication-sealed, grease-lubricated upper high-speed and intermediate bearings and oil-lubricated lower bearings reduce oil levels, churning and foaming for cooler operation. Large oil capacity also helps keep the unit cooler for maximum life. A magnetic oil drain plug is provided. 
• Easy maintenance - easily accessible oil fill opening and oil drain plugs let you perform required maintenance without removing any covers or guards. Standard, automotive-type, quick-check dipstick allows fast, easy oil checks.
• Typical mounting options -open tank, stuffing box, double or single mechanical seal.
