The HPHT Consistometer Paddle Assembly is a key stirring component used in high-pressure high-temperature consistometers for oil well cement slurry conditioning and thickening-time testing.
During a consistometer test, the paddle assembly rotates inside the slurry cup to maintain controlled slurry movement and reproduce the shear conditions required by the testing procedure. Stable and consistent paddle rotation is essential for obtaining reliable cement slurry thickening-time and consistency data.
NITHONS supplies paddle assemblies for HPHT/HTHP consistometers as replacement and spare parts for cementing laboratories, oilfield service companies, research institutes and equipment maintenance teams.
The assembly can be supplied as a complete set including the central shaft, paddle and elastic pin, with different shaft configurations available according to the consistometer model.
An HPHT consistometer paddle assembly is the rotating stirring assembly installed inside the slurry cup of a high-temperature high-pressure consistometer.
Its main functions are to:
Maintain uniform movement of the cement slurry
Provide controlled and repeatable slurry shearing
Keep the cement slurry properly conditioned during testing
Support reliable thickening-time measurements
Simulate the controlled shear environment used during cement placement
Because the paddle assembly is continuously exposed to cement slurry, temperature, pressure and mechanical rotation, it is considered a wear and replacement component of an HPHT consistometer.
For laboratories performing cement thickening-time tests regularly, keeping a spare paddle assembly in stock can help reduce equipment downtime.
A complete HPHT consistometer paddle assembly generally consists of three main components:
The central shaft connects the paddle assembly to the consistometer drive mechanism and transfers rotational movement to the paddle.
Different shaft lengths can be supplied according to the equipment configuration.
The paddle is the primary slurry-contacting component. Its geometry is designed to provide controlled mixing and shearing of the cement slurry during the consistometer test.
Proper paddle geometry is important for maintaining repeatable testing conditions.
The elastic pin secures the paddle to the central shaft and helps maintain a stable mechanical connection during rotation.
Designed for use in HPHT/HTHP consistometer applications where cement slurry is conditioned under elevated temperature and pressure.
The paddle assembly is designed for stable rotation, helping minimize unnecessary vibration and maintain consistent slurry shearing during testing.
Materials are selected for demanding cement laboratory environments involving high temperature, cement slurry and repeated mechanical operation.
The shaft, paddle and elastic pin can be supplied as a complete assembly for convenient replacement and maintenance.
Different shaft configurations are available according to the consistometer model and installation requirements.
The paddle assembly can be used as a replacement or spare component to help laboratories maintain their consistometer in working condition.

The HPHT consistometer paddle assembly is commonly used for:
Oil well cement thickening-time testing
HPHT cement slurry conditioning
Cement slurry consistency testing
Cement laboratory maintenance
Consistometer replacement parts
Oilfield service company laboratories
Cement research and development laboratories
Replacement of worn or damaged stirring components
The paddle assembly is a working component that is exposed to continuous rotation and direct contact with cement slurry.
Over time, the paddle, shaft or connecting pin may require inspection or replacement due to:
Mechanical wear
Cement buildup
Corrosion
Deformation
Damage during cleaning
Long-term laboratory use
Replacing the complete paddle assembly can be a practical solution when the original assembly is worn or damaged.
NITHONS can supply complete assemblies as well as model-specific configurations according to customer requirements.
NITHONS paddle assemblies are designed for API-compatible cement testing applications and can be supplied for selected consistometer models from different manufacturers.
Compatibility should always be confirmed according to the exact equipment model, shaft dimensions and paddle configuration before ordering.
If you are replacing an existing paddle assembly, please send us the consistometer model number or a photo of your existing paddle assembly. We can check the configuration for you.
The paddle assembly directly affects the movement and shearing of the cement slurry during a consistometer test.
An improperly matched, worn or damaged paddle may affect:
Slurry movement
Shear conditions
Consistency measurements
Test repeatability
Mechanical stability of the consistometer
Using a properly matched replacement paddle assembly helps maintain stable test conditions and supports reliable laboratory results.
