  • Belt drive → Provides practical power transmission with accessible drive components
  • High-efficiency impeller geometry → Converts drive power into useful liquid circulation
  • External drive and seal access → Helps maintenance teams inspect and service key components
  • Positive tank shut-off concept where configured → Supports seal service without routine tank draining
  • Application-specific material options → Supports selection for the process liquid and environment
  • Industrial tank mixing platform → Supports blending, homogeneity and temperature-uniformity duties
  • AxFlow product-selection support → Helps match mixer configuration to tank geometry and duty
  • Service and spare-parts support from AxFlow → Helps plan maintenance and lifecycle requirements

Product Description

Plenty STM Swivel Angle with Belt Drive is used in industrial tanks where liquid movement has a direct effect on product uniformity, temperature distribution, sediment control or storage stability. It is suited to storage and process tanks where operators need to redirect flow across the tank floor for sludge suspension, BS&W control or tank-cleaning duties. Typical selection factors include tank geometry, liquid properties, operating level, required circulation pattern and the consequences of poor mixing for product quality or maintenance.

The STM configuration combines side-entry installation with an adjustable swivel angle, allowing the impeller discharge to be redirected rather than fixed in one position. This is particularly useful where settled solids or bottom water must be mobilised across different areas of the tank. The drive and sealing components remain outside the vessel, supporting access for inspection and planned maintenance.

The STM combines a heavy-duty belt drive with a swivel mechanism that can change the mixer entry angle by up to 30°. A one-piece helical-pitch impeller and positive tank shut-off arrangement support efficient circulation and maintainability. Exact motor, seal, material and mounting configuration should be matched to the tank, liquid and operating environment during selection.

From a lifecycle perspective, the side-entry arrangement can reduce the need for intrusive tank access while keeping major service components accessible from outside the vessel. Correct sizing and positioning help maintain process continuity, reduce the risk of stratification or sediment-related problems and support predictable maintenance planning. AxFlow can help confirm the correct Plenty configuration, materials and availability for the application.

Oil and Gas

Plenty STM Swivel Angle with Belt Drive is used for industrial tank mixing and liquid circulation where product uniformity, temperature distribution or sediment behaviour must be controlled. The exact duty depends on tank geometry, liquid properties and the required flow pattern. AxFlow can help assess whether the configuration fits the application.
The STM is differentiated by its swivel-angle arrangement and belt drive concept. These construction choices influence flow direction, maintenance access and how the mixer is matched to the tank. Selection should therefore be based on the actual tank duty rather than series name alone.
Check tank dimensions, liquid level, density, viscosity, solids behaviour, required mixing objective, mounting position and operating environment. Motor power, seal arrangement, wetted materials and certification requirements must also match the duty. AxFlow can support the final configuration and availability check.
Key drive, bearing and sealing components are located outside the vessel, which supports external inspection and maintenance. Plenty side-entry platforms can also be configured with a positive tank shut-off arrangement for seal and bearing service under full-tank conditions. The exact service procedure depends on the selected configuration and site safety requirements.
AxFlow supplies Plenty mixing equipment and supports product selection for industrial tank applications. AxFlow can help identify the appropriate configuration, materials and service requirements for the duty. Contact AxFlow for availability, spare-parts support and a quotation.
