Specially-designed Agitator

Specially-designed Agitator

Agitation is a process that involves complex operating conditions, such as the purpose of agitation, solution properties, temperature, and pressure. Most of these challenges cannot be handled with off-the-shelf, standard models. Techmix excels at designing and manufacturing special agitators that are not possible with standard models.

Agitator driven by a V-belt

Agitator using a V-belt for driving the agitation shaft.

【 Features 】
  • No noise is generated because no gear is used for slowdown (or speeding up).
  • The agitator can be reduced in height as the electric motor is placed horizontally.
  • Enables low reduction ratios which are not possible with gears.
  • Rotational frequency can be changed even after installation by replacing pulleys.
  • The shaft seal part works with all types, including gland packing, dry mechanical seal, and normal mechanical seal.

【 Applications 】

  • A standard type of agitator applicable to almost all agitator operations.
  • Since the applicable rotational frequency is relatively high, the agitator is used very often for dispersion at high rotational frequency.
  • Since the rotational frequency can be easily changed after installation, the agitator is often employed for applications that handle high-viscosity liquids (non-Newtonian fluids in particular) and the load power is hard to predict.

Horizontal agitator for side mounting

Horizontal agitator for mounting on the side wall of a tank

【 Features 】
  • Liquid leakage is minimized by using a single or double mechanical seal and the gland packing design.
  • Low-noise, compact design thanks to V-belt driving.
  • The agitating blade uses marine type propeller blades that offer high discharging performance.
  • The ability to replace a mechanical seal or gland packing at full level condition is available as an optional feature.

【 Applications 】

  • Low power is preferred for agitation in large-capacity tanks, such as storage or waste liquid tanks.
  • For high tanks, a vertical agitator would be costly and its axis be unjustifiably long.
  • Ideal for relatively mild agitation in liquid-liquid and liquid-solid conditions.

Agitator linked directly with a speed reducer containing an orthogonal shaft (hollow shaft)

Input from an electric motor is applied to the side face and is linked directly to a speed reducer placed in orthogonal position.

【 Features 】
  • The agitator can be reduced in height as the electric motor is placed horizontally.
  • Depending on working conditions, the bearing of the agitator can be omitted to provide an even lower, more compact agitator.
  • The shaft seal part works with all types, including gland packing, dry mechanical seal, and normal mechanical seal.
  • A wide selection of various agitating blades to suit different purposes.

【 Applications 】

  • In cases where the ceiling of the building is too low to install or service an agitator.
  • Space for replacement work is not available for renewing existing equipment.
  • An agitator of smaller weight is desirable in view of the limited strength of the target agitation tank.

Agitator mounted with a portable clamp

This agitator is mounted on a tank via a clamp, rather than flanges, for operation where a shaft seal part is required.

【 Features 】
  • The small, lightweight agitator does not place a heavy burden on the agitation tank.
  • Easy to install and maintain.
  • The simple structure means lower price.
  • The gland packing is made of non-asbestos Teflon, making it usable for food uses.

【 Applications 】

  • The agitation tank is too small to be fixed with flanges.
  • Space for installing an agitator is not available as there are many nozzles and manholes on the top lid of the agitation tank.

Multi-shaft agitator

An agitator having two or more agitation shafts per tank.

【 Features 】
  • Different agitation functions are simultaneously applied to the fluid in the tank to enable more intense agitation in a shorter time.
  • Sharing of different agitation functions reduces power consumption and cost.
  • A mechanical seal of special structure can be used.

【 Applications 】

  • To agitate a highly viscous or less-fluid liquid by applying strong shear force (e.g., for dispersing high-concentration slurry such as paint or magnetic substances).
  • To accomplish more intense agitation in a shorter time by avoiding entrapment of air bubbles.
