nov mud pump liner pressure ratings brands

NOV 12-P-160 Mud Pump is rated at 1600 input horsepower (1193 kw) at 120 strokes per minute, with a 12-inch (304.8 mm) stroke. Multiple liner sizes allow pressures and volumes to handle circulation requirements in deep drilling applications.

Flexibility: Compact engineering provides higher efficiency in less space. The NOV 12-P-160 Triplex Mud Pump light weight and flexible design make it easily adaptable to a variety of rig configurations. This provides flexibility as drilling requirements and conditions change.

Fluid End Modules: NOV offers a choice of fluid end modules and valve covers for every P Series pump model to select the fluid end module that exactly matches drilling requirements. All pump models can be equipped with either the standard or premium forged, two-piece interchangeable fluid modules

Since the NOV A1700-PT Triplex Mud Pump was built approximately 60 years ago, the industry has widely accepted the three cylinder or triplex style pump. Triplex mud pumps are manufactured worldwide, and many companies have emulated the original design and developed an improved form of the triplex pump in the past decade.

NOV A1700-PT Triplex Mud Pumps have many advantages they weight 30% less than a duplex of equal horsepower or kilowatts. The lighter weight parts are easier to handle and therefore easier to maintain. The other advantages include;They cost less to operate

One of the more important advantages of triplex over duplex pumps, is that they can move large volumes of mud at the higher pressure is required for modern deep hole drilling.

NOV A1700-PT Triplex Mud Pump is gradually phasing out duplex units. In a triplex pump, the pistons discharge mud only when they move forward in the liner. Then, when they moved back they draw in mud on the same side of the piston. Because of this, they are also called “single acting.” Single acting triplex pumps, pump mud at a relatively high speeds. NOV A1700-PT Triplex Mud Pump has three pistons each moving in its own liner. It also has three intake valves and three discharge valves. It also has a pulsation dampener in the discharge line.

Drilling consumables such as mud pump systems and their components can drastically increase your uptime while reducing costs and health/safety/environmental (HSE) risks. To support your drilling needs, Forum’s patented P-Quip® mud pump system offers a single-source solution that integrates high-quality fluid end components for maximum longevity and performance.

With more than 20 years of successful operation in severe environments, P-Quip offers a proven track record for the lowest cost of ownership in the industry. As part of our commitment to quality, our mud pump parts use patented Banded Bore™ technology that significantly reduces stress concentrations and leads to longer module life.

Function: Mud Pump Liner also called the cylinder liner. The cylinder liner is the core accessory of the mud pump, which has the functions of storing mud, bearing pressure and completing the suction and discharge of mud. Because the cylinder liner is in direct contact with the mud, it is easy to be worn and corroded by the tiny sand particles, acid and alkali liquid in the mud during work. As a result, the inner diameter of the cylinder liner becomes larger, leakage occurs in the seal between the cylinder liner and the piston, and the pressure is reduced. The cylinder liner is scrapped eventually. Cylinder liner is a one-time wearable part that cannot be reused, and its life span directly affects the normal operation and cost of the drilling operation.

Bimetal Liners are also known as double metal liners. Forged steel pipe 45# (ASTM1045) is used for the outer sleeve, the normalizing hardness: 160BHN (HB180-200); elongation: 17%; tensile strength is not less than 85000PSI; yield strength is not less than 60000 PSI; The inner sleeve material is high chromium wear-resistant cast iron, with chromium content of 26-28%; thickness is 0.25 to 0.35 inches (6.35-8.89 mm), and the standard thickness is 7 mm. Usually, the service life is 800 hours under normal drilling conditions.

The inner liner is made of zirconia or aluminium oxide, and the outer sleeve is made of 45# (ASTM1045) forged steel. It has the advantages of more wear resistance, corrosion resistance, high-pressure resistance, high-temperature resistance, high strength and high hardness than metal cylinder liners. The service life is more than 4000 hours under normal drilling conditions.

The piston assembly is one of the main parts of the hydraulic end system of the mud pump, and it is also one of the vulnerable parts of the drilling work. The discharge pressure of the mud pump is generated by the reciprocating linear movement of the piston assembly in the piston.

NBR rubber is suitable for an ordinary drilling working environment with working pressure below 20Mpa, and the working temperature is not higher than 120℃. Excellent wear resistance, chemical resistance and long service life.

Polyurethane rubber has excellent oil resistance and wear resistance. The working temperature is not higher than 120℃, which is suitable for oil-based mud with working pressure below 35Mpa and working environment with high sand content.

Lake Petro has over 10 years of experience in Liners and Pistons, we export a large amount of mud pump parts to many countries and regions in the world. If you are interested in any of our products, please contact sales@lakepetro.com.

Mud Pump Pulsation Dampener is usually installed on the discharge line to reduce the fluctuation of pressure and displacement of the drilling mud pump.

Mud Pump Pulsation Dampener is a pneumatic device built into the outflow line of each UUD pump to dampen the pressure fluctuations resulting from the action of the pump. Although presented as a surge tank, this device is really a device that can be tuned to greatly diminish the output pulsations transmitted downstream from the mud pump. Unfortunately, the effectiveness of the pulsation dampener is a function of both output pump pressure and frequency of the pump pulsations.
