6 mud pump liner pressure ratings brands

Tired of changing mud pump pistons? We have your solution. The TD will work in all types of drilling mud including oil based, synthetic and water based. It was specifically designed to work in applications where water based mud is used or in situations where WBM is used on the top side & OBM is used on the bottom end. This eliminates the need for changing the piston midway through the drilling program. The “TD” or “Total Depth” name reflects our commitment to make a single piston that will last from “spud” to “TD”. This piston has been engineered with a unique friction reducing material bonded into the urethane of the sealing lip. Because the TD is built to withstand friction in the liner, wear on your parts is minimized and savings is maximized. The Patriot™ TD is also designed to meet pressures of 7500 psi as well as temperatures up to 220 degrees.

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.

The OEM series PZ mud pump features a pleasing shape, advanced design, reasonable structure, and high efficiency. At power end, pinion shaft and bull gear are both hard teeth, wear-resistant, and transmission stable.

All parts at power end except the lubrication oil pump and all parts of the fluid end are completely exchangeable with OEM pumps from the United States.

The pump frame is gang welding on casting and steel–plate construction. The bearing housings of the crankshaft, the transmission shaft, and guides seats are made of steel castings and are welded to the frame after rough–machined. They are stress–relieved through heat-treated aging after welded.

The cylinder is made of VD refined forged steel. And the three valves on each pump are exchangeable. The direct cylinder (the valve on the valve) design may reduce the volume and may improve the efficiency of it. As the customer required, we may nickel plating the surface, which may prevent the cylinder from erosion.

The taper of the valve seat is 1:6. The bottom of the seat is provided with a shoulder to be suitable for high pressure. The valve seat and the upper step of the valve seat conform to API 7K. The discharge valve and the suction valve are exchangeable.

There are two types of liners: high-grade liner and plain liner. The high – grade liner is made of carbon steel as a base metal, which is cast or inserted with high – chrome alloy – steel to ensure wearability, and the hardness has reached the HRC60-65. The plain liner is made of low – carbon steel which is carburized and quenched inside to enhance the surface hardness.

The liner can be inserted from the liner room in front of the cylinder. After the liner has been fixed, the liner and the liner room should be fixed in three holes in the front plate of the rack and should be connected with the cylinder with bolts.

The piston rod conforms to the spec API-7K. The piston is fixed with the 1-1/2＂locking nuts. Without weariness of the piston and with the piston through the separated water tank, the piston spray pump may spray water or erosion-proof water to lubricate and to cool.

The discharge site of the pump involves a discharge pulsation dampener, relief valve, and discharge screen. The suction port is 12” flange. Three cylinders at the fluid end are of through-way stepwise structure, realize suction and discharge. The fluid end is composed of three fluid modules (cylinders), each of which is a sectional and communicating construction. The suction and discharge are accomplished by suction and discharge pipes. The suction and discharge valves are vertically aligned with each other to minimize the volumetric clearance.

The discharge pulsation dampener is spherical and pre–pressured. It’s Max. The working pressure is 5000PSI, and the volume is 75L (20 gallons). The pulsation dampener is connected to the air filler and to the pressure gauge, using 3/4” – 14NPT and 1/4” – 18NPT respectively.

Spray system includes a spray pump, cooling water box, and spray hose. It function involves cooling and washing cylinder liner and piston, which will extend liner and piston’s service life.

The spray system is a kind of eccentric pump, imported from the United States. The spray pump can be V-belt driven or electric driven. Use water as a cooling lubricant.

Spray hose is installed in the clamp connecting intermediate rod and piston rod, and can reciprocating run along with piston. The spray nozzle is very close to the piston face and can make cooling lubricant wash contact face of piston and liner. A fixed spray hose also can be used. Spray hose is durable.

The power end adopts force lubrication and splash lubrication. The gear oil pump in the reservoir transfers pressure oil to the crosshead, intermediate rod, guide, and each bearing through lubricating lines. The working status of the gear oil pump can be checked through the vacuum gauge aside from the frame.

We offer Liners with Ceramic (Zirconia and Aluminium oxide) and Steel (Metal and Bi-metal) materials for all common brands of the mud pump and triplex mud pump.

Bi-metal liners (double metal liners) are made of forged steel shell and wear-resistant sleeve of high chromium iron. In the production process, the size accuracy should be strictly controlled, which can ensure that they can be easily and stably installed. The inner sleeve with high finish and hardness is wear-resistant, corrosion-resistant and has a long service life. The bi-metal liners are suitable for a lot of bad working conditions. Its service life is more than 800 hours.

Ceramic Liners are made of a ceramic inner sleeve and a forged steel outer shell. The service life of ceramic liners is about 4000 to 10000 hours, the minimum time is at least 2000 hours, which is a lot more than bi-metal liners. Because of the phase transformation toughen technology, the ceramic liners have the features of wear-resistance, erosion-resistance, high-pressure-resistance, high hardness and strength. Zirconia type and Alumina type are common type of ceramic sleeve. Compared with Alumina type, Zirconia type liners have better toughness properties and a much longer service life. Piston wear and water consumption for lubrication can be reduced as well.
