M7150 Stirred Fluid Loss Tester


  • Dimensions: 23" Width x 21" Depth x 38" Height
  • Max Pressure: 2,000 psi | Max Temperature: 450 °F (232 °C)

The M7150 Stirred Fluid Loss Tester provides a reliable means to determine the fluid loss properties of muds and slurries under HPHT conditions.

It pre-conditions and tests cement slurry in the same cell vessel, removing the necessity of manually transferring heated slurry to another cell vessel, thus reducing operator contact with and danger to extremely hot slurry. The apparatus is designed to be safe, reliable, economic and easy to use.

The M7150 simulates down-hole conditions where slurry dehydration might occur. Cement slurry is poured into a vessel and heated by a heating jacket. A PID temperature controller controls the applied temperature as the slurry is stirred with a rotating paddle at 150 RPM (custom 200 RPM is also available) according to API Specifications. Back pressure is applied to the back pressure receiver, where the filtrate is collected after it is forced through a filter medium. The fluid-loss rate is determined by the volume of filtrate collected per unit of time.

We offer an optional PC-controlled temperature ramping and filtrate weight recording feature for our M7150 Stirred Fluid Loss Tester.
