Offshore Pumping & Mixing Equipment
From superior sound abatement to vibration and dust control, Halliburton's offshore pumping equipment is the perfect choice for offshore projects. Our skids are equipped with standard features such as density-control and data-recording systems to ensure consistent and predictable slurry performance.
Halliburton offers two choices for high-pressure pumping:
- Halliburton’s HT-400â„¢ High-Pressure Pump
- Halliburton’s HQ-2000â„¢ High-Pressure Pump
The HT-400 pump
- Type certified horizontal 4-in. by 8-in. pump with “L” spacers
- Single-acting plunger type
- Fluid end pressure rating of 15,000 psi with 4-in. plungers
- Worm reductions gear drive ratio of 8.4:1, totally enclosed in an all-steel power case
- Acid-resistant steel plungers capable of pumping acid, water, drilling fluids and other fluids , and of course, cement slurries
- 3-in. style 1502 threaded discharge flange and 3-in by 2-in Chicksan crossover
- Maximum discharge rate of each pump with 4-in. plungers is 8 ½ barrels per minute (bpm) for a total unit discharge rate of 17 bpm
The HQ-2000 pump
- Type certified horizontal 4½ -in. by 8-in. quintiplex pump with “L” spacers
- Single-acting plunger type
- Fluid end pressure rating of 11,200 psi with 4½ -in. plungers
- Single helical gear set with case carburized and ground teeth with a gear reduction ration of 6.313:1; totally enclosed in an all-steel power case
- Acid-resistant steel plungers capable of pumping acid, water, drilling fluids and other fluids , and of course, cement slurries
- Two 3-in. style 1502 threaded discharge flange
- Maximum discharge rate of each pump with 4½ -in. plungers is 23.9 bpm for a total skid unit discharge rate of 32.2 bpm

The Model 410 SCFM Compressor Skid – Halliburton-designed air-compressor skid supplies low-pressure air to the bulk system.
The PLC Control System – Advanced mixing control system designed for hazardous area operations offshore.
Automatic Density Control (ADC® mixing system)
- UNIPRO™ II computer system provides automatic control over the flow rate of incoming dry material and mixing water (automatic operational mode)
- Two back up systems: (1) electrically overrides the UNIPRO II system with a potentiometer in the control stand (manual electric operational mode); (2) manual system that bypasses the hydraulic system and manually moves the water valve and cement throttling valve (manual mechanical emergency operational mode)
- Signals are received from the 3-in. mixing water flow meter and the 3-in. density meter, adjusting the incoming flow to the correct rate and density
- Allows preprogramming of up to three stages of cement blends
- Accommodates rate, density, and stage changes during the job
RCM® IIIr High-Energy Mixing System
The RCM® IIIr mixer mixes pneumatically conveyed bulk dry cement and cement material with the mixing water for a thoroughly mixed and homogenous slurry.
- Provides a linear relationship and a single control point between valve position and dry bulk material rate and water rate
- Dry cement feed rate controlled by cement throttle valve atop mixer
- Fresh water entry feed rate controlled by a rotary-jet valve located in the mixer
- Cement dust is minimized by the wetting of dust particles before they can escape to the atmosphere
- RCM Tank: Pre-mix compartment of the RCM tank receives the cement slurry, mixing it again with mechanical agitators before returning it back to the RCM IIIr mixer via the re-circulating centrifugal pump
- Designed to re-circulate slurry through Density Sensor and back into mixer to provide higher mixing energy
- Allows re-circulated slurry to mix with the incoming water and cement for more effective mixing
- Diffuses the energy of the re-circulated and newly mixed slurries to minimize air entrainment
