Central Drive Clarifier

Clarifier Mechanisms

Vishuddhi has a tradition of supplying the industry's highest quality and most reliable clarifier mechanisms from basic bridge or pipe supported mechanism to those with the most complex and demanding special requirements. Vishuddhi mechanism are driven by High torque designed drive units that have corrosion resistant and precision ratings superior to any drive on the market, and exceed the industry's highest standards.

Vishuddhi's versatile Clarifiers with central and peripheral drive are specially designed and developed for a vast range of applications. High toque gear drive with overload protection facility provided for minimal maintenance. Vishuddhi offers a wide range of clarifiers / clariflocculators ranging from 5 to 50 meter diameter tanks.

The complete range of driveheads are available as both lift and non-lift designs. Rake height indication and remote indication of rake height and rake torque are available.


Drive mechanism and controls


The new drive mechanism range has been developed to improve torque capacity, reduce costs and rationalize component parts. The main advantages of this range of drive heads can be summarized as follows.


·         Proven design extended to all drive head sizes

·         Substantial slewing ring main bearing used for all sizes of drive heads. This bearing accommodates all tipping moments from rake system without affecting worm wheel alignment, thus further extending worm and wormwheel life.

·         Designs available for both bridge and centre pier mounting. Increased torque capacity.

·         Main spur wheel machined from spheroildal cast iron for maximum wear life and torque capacity. Reliable and adjustable torque sensing

·         Torque sensing by electronic main drive slip sensor with fixed high torque alarm and motor cut off values

·         Adjustable rake raise. This gives great control over the thickener or clarifier operation. Improved design for easier maintenance In-drive system consists of in-line, high efficiency planetary gearbox and main motor.
