Advantages of NOI Mud Pumps

Nearly Zero Pulsation Output
Compared to traditional three-cylinder pumps, the pressure pulsation is reduced by up to 92%, providing unprecedented clarity for MWD tools and significantly extending the life of downstream high-pressure manifold.

Excellence In Power Density
The pump's overall weight is reduced by 30-40% and its footprint is reduced by 45%, providing unmatched advantages for upgrades on space-constrained offshore platforms and rigs.

Uniquely Flexible Operation
Unlike later fixed cylinder liner models, the Old FE Version retains the capability to replace cylinder liners, enabling operators to flexibly switch between ultra-high pressure and high displacement according to well section requirements.

Applications of NOI Mud Pumps

Deepwater and ultra-deepwater drilling
Its excellent power density and reliability make it an ideal choice for valuable deepwater drilling platforms and drilling ships in space.

High-precision geological steering drilling
The nearly pulsless fluid flow provides extremely clear signals for MWD/LWD tools, which is the key to achieving complex wellbore trajectory and reservoir evaluation maximization.

Onshore drilling for flexible conditions
For operations that require frequent switching between high pressure cementing/fracturing and large displacement hole cleaning, the replaceable sleeve design of the older hydraulic end provides valuable flexibility and reduces non-productive time.

Precautions to Observe During the Operation of NOI Mud Pumps

The mud pump, high-pressure water pump and tailings pump should always check whether the oil level is at the center line of the oil window. If the oil level is too low, please replenish it in time.

During the operation of the mud pump, a special person should always observe the running state of the diesel engine, such as oil temperature, water temperature, oil pressure and whether the fuel oil is normal. If an abnormality is found, it needs to be shut down, and the mud pump will be restarted after the fault is eliminated.

All new diesel engines need to be replaced within 200 hours of operation during the running-in period of the new diesel engine, and the oil filter element, diesel filter element, etc. need to be replaced, and subsequent maintenance needs to be carried out within 250 hours of equipment operation.

The mud pump needs to be buttered once every 20 hours of operation.

The mud pump packing needs to be checked frequently for looseness. Generally, it is advisable to have 60 drops of water dripping out per minute. The sand pump packing needs to use pure cotton yarn oil-containing packing or butter packing.
