FEATURES

The TM and STM Series Side Entry Mixers represent a culmination of over 60 years of engineering innovation, setting the global benchmark in side-entry tank mixing technology. Designed for efficiency, durability, and ease of maintenance, these mixers are ideal for applications where precise fluid motion and robust performance are critical.

Key Features:

  • High-efficiency Impellers: One-piece helical pitch impellers ensure cavitation-free suction, high thrust, and optimized energy usage.
  • Durable Belt Drive System: Fire-resistant anti-static (FRAS) torque belts transmit power with precision and reliability.
  • Swivel Angle Flexibility (STM Series): Adjustable angles (up to 30°) enable comprehensive tank coverage, ensuring even mixing and sediment suspension.
  • Compact and Accessible Design: Facilitates easy installation, maintenance, and operational longevity.

The mixers’ advanced design ensures they perform in a wide range of demanding industrial applications, offering superior energy efficiency compared to jet mixing systems.

Key Applications

The TM and STM Series mixers are widely used across industries:

  • Oil & Gas: Crude oil storage, BS&W control, sludge suspension.
  • Biofuels and Renewable Oils: Ensuring homogeneity and blending.
  • Wastewater Treatment: Effective mixing of wastewater and treatment chemicals.
  • Chemical Processing: Uniform blending of components and temperature regulation.
  • Edible Oils: Maintaining product integrity during storage and transfer.

OPTIONS & PERFORMANCE

The TM and STM Series mixers offer several customizable options to meet unique operational requirements:

Plenty Mixers Shaft Seal

Automatic Swivel Actuators (STM Series):

  • Timer-controlled electric motor swivels for precision mixing.
  • Shaft-driven actuators for continuous operation without additional field wiring.

Tank Shut-off Device: The tank shut-off device ensures seal and bearing replacement can be performed without draining the tank, reducing downtime.

  • Metal-to-metal tapered faces for secure sealing.
  • Corrosion-resistant materials for durability.
  • Safety check valve verifies shut-off effectiveness.
  • Eliminates reliance on O-rings or gaskets that may degrade over time.

Durable Bearings: Long-life pre-lubricated bearings designed for heavy-duty usage.

Mechanical Seal: Designed to handle a wide range of fluids, from asphalt to xylene, ensuring minimal leakage and maximum reliability.

Seal Features:

  • Fully enclosed within a housing to protect against wear and contamination.
  • Close-clearance throttle bush reduces leakage risks during seal failure.
  • Safety check valve ensures the seal chamber is filled with liquid before operation.

Available Seal Options:

  • Double Mechanical Seal
  • Cartridge Seal
  • High-Temperature Sealing Units
  • API/682-compliant Seals
