STIR-PAK

STIR-PAK is a line of overhead stirrer components and laboratory mixing accessories. The brand covers shafts, impellers, support stands, and related hardware used to assemble and operate overhead stirring systems in laboratory and industrial settings. Products are identified by manufacturer part numbers in the 04552-xx series, which supports consistent reordering and cross-referencing across installations. The catalog includes stainless steel shafts in multiple lengths, radial-blade impellers, and L-shaped support stands with cast steel bases. These components are used for mixing, blending, and agitating liquids, suspensions, and slurries in applications where a top-mounted drive unit is required. The product family is defined by mechanical compatibility: shaft diameter, shaft length, blade diameter, blade shape, and mounting interface. For technical buyers, the relevant specifications are material of construction, dimensions, and compatibility with standard overhead stirrer chucks and couplings. Shafts are available in 3/8 in diameter with lengths of 18 in, 24 in, and 30 in, allowing users to match immersion depth to vessel geometry. Impellers are three-blade radial types with a 3/8 in shaft diameter and blade diameters such as 2 in, constructed from stainless steel for corrosion resistance in aqueous and mildly aggressive media. The support stand has a cast steel base and a 5/8 in diameter rod, 29 in long, with an overall length of 11 3/4 in, providing a stable mounting point for mixer drives and positioning hardware. These are not sealed or IP-rated instruments; they are mechanical components intended for dry or splash-exposed laboratory and industrial environments. 3G Electric supplies the STIR-PAK line as part of its industrial equipment catalog, with logistics support for global delivery. The company serves plant engineers, maintenance managers, and procurement specialists who need to specify replacement shafts, impellers, and stands by part number and dimension. Because the components are standardized by diameter and length, they can be integrated into existing overhead stirrer setups without proprietary adapters in many cases. 3G Electric provides access to multiple SKUs, including 8MWX7, 8MWX6, 8MXN0, 8ANU8, 8YA69, and 8AN87, each with published specifications for material, dimensions, and part number. This allows buyers to verify fit and function before ordering. The STIR-PAK range is suited to routine mixing tasks where a simple, durable mechanical assembly is preferred over complex integrated systems. Typical users include quality control laboratories, pilot plants, and production areas that handle small to medium batches of liquids or slurries. The components are also used in educational and research laboratories where overhead stirring is a standard unit operation. 3G Electric supports the line by stocking multiple variants and providing part-number-level identification, which reduces ambiguity in procurement and maintenance workflows. For specification questions, the relevant data points are shaft diameter, shaft length, blade diameter, blade shape, rod diameter, rod length, and base dimensions. These are published for each SKU in the product list. The brand does not publish IP ratings for these items, and they should not be treated as washdown or submersible equipment. Instead, they are mechanical accessories for overhead stirrers, and their performance depends on the drive unit, vessel, and process conditions. 3G Electric’s role is to make the STIR-PAK catalog accessible to international buyers with clear part numbers and specifications, so that replacement and expansion of existing mixing setups can be handled through standard procurement channels.

Frequently asked questions

Common questions about STIR-PAK from 3G Electric.

What shaft diameters and lengths are available in the STIR-PAK overhead stirrer shaft range?

STIR-PAK overhead stirrer shafts are offered with a 3/8 in shaft diameter. Published lengths include 18 in (MPN 04552-35), 24 in (MPN 04552-00), and 30 in (MPN 04552-05). All are made of stainless steel. The shaft diameter determines compatibility with standard overhead stirrer chucks and couplings, while the length is selected based on the required immersion depth and vessel height. These shafts are intended for laboratory and industrial mixing of liquids, suspensions, and slurries. When replacing a shaft, verify both the diameter and the length against the existing drive unit and vessel geometry.

What are the specifications of the STIR-PAK radial blade impellers?

STIR-PAK radial blade impellers are three-blade propellers made of stainless steel. They have a 3/8 in shaft diameter and are available with blade diameters such as 2 in. The radial blade shape is intended for efficient fluid movement in mixing and agitation tasks. These impellers are used in laboratory and industrial settings for liquids, suspensions, and slurries. The 3/8 in shaft diameter matches the STIR-PAK shaft range, allowing direct mounting. When selecting an impeller, consider the blade diameter relative to the vessel diameter and the desired flow pattern. The stainless steel construction provides corrosion resistance in aqueous and mildly aggressive media.

What is included with the STIR-PAK mixer support stand, and what are its dimensions?

The STIR-PAK mixer support stand (MPN 04552-80) is an L-shaped support stand with a rod included. It has a cast steel base and a 5/8 in diameter rod that is 29 in long. The overall length is 11 3/4 in. This stand is used for mounting and positioning mixers in laboratory or industrial settings. The cast steel base provides stability, and the rod allows the mixer drive to be clamped at the required height. The 5/8 in rod diameter is a common size for laboratory clamps and mounting hardware. Verify that your mixer drive and clamps are compatible with this rod diameter before ordering.

Are STIR-PAK shafts and impellers compatible with each other?

Yes. STIR-PAK overhead stirrer shafts and radial blade impellers share a 3/8 in shaft diameter. This allows the impellers to be mounted directly onto the shafts without adapters. The shafts are available in 18 in, 24 in, and 30 in lengths, and the impellers are available with blade diameters such as 2 in. This dimensional consistency simplifies assembly and replacement. However, always confirm the specific part numbers and dimensions for your application, as other components in the mixing setup, such as the drive unit and chuck, must also be compatible. The published specifications for each SKU provide the necessary data for verification.

What materials are used in STIR-PAK overhead stirrer components?

STIR-PAK overhead stirrer shafts and impellers are constructed from stainless steel. The support stand has a cast steel base and a steel rod. Stainless steel is selected for corrosion resistance in laboratory and industrial environments where mixing involves aqueous solutions, suspensions, or slurries. It is not intended for highly corrosive chemicals or submersible operation unless specifically rated. The material of construction is listed for each SKU in the product specifications. For applications involving aggressive media, verify chemical compatibility with stainless steel before use. These components are mechanical accessories and do not carry IP ratings for washdown or immersion.

How does 3G Electric support the STIR-PAK product line for international buyers?

3G Electric supplies STIR-PAK overhead stirrer components as part of its industrial equipment catalog. The company provides part-number-level identification for SKUs such as 8MWX7, 8MWX6, 8MXN0, 8ANU8, 8YA69, and 8AN87, along with published specifications for material, dimensions, and compatibility. This allows procurement specialists and maintenance managers to verify fit and function before ordering. 3G Electric offers logistics support for global delivery, so buyers outside Singapore can source these components through standard procurement channels. The focus is on making the STIR-PAK range accessible with clear technical data, reducing ambiguity in replacement and expansion of existing mixing setups.
