5.5 mud pump liner pressure ratings factory

GDEP is the original creator of the drilling pump and continues to set the standard for durable, high-quality drilling pumps that can withstand the world’s toughest drilling environments. Starting with our PZ7 and rounding out with the market"s most popular pump, the PZ1600, our PZ Series of pumps are the perfect choice for today"s high-pressure drilling applications.

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.

Centerline Manufacturing is committed to the highest level of customer service quality.  Every Centerline pump is comprehensively and repeatedly tested at diverse pressure levels to assure that it goes to our customer in perfect operational order. Centerline technicians work to ensure that our customers fully understand the operation of the model being delivered.  If a customer"s pump is down, we understand the importance of timely response and parts availability.  Centerline technicians will assess the problem and make repairs to bring the pump back into new specification. The Centerline mud pump technicians are well versed and qualified to operate and repair any product that is provided to the customer.

Lake Petro provides high quality Mud Pump Parts including Mud Pump Liners, Mud Pump Fluid End Module, piston, Valve and Seat etc. With more than 10 years of experience in the oil and gas industry, we are dedicated to help and support our loyal clients with the most cost-effective and quality Liners and Pistons. We also provide mud pump price and mud pump for sale.

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.

Seal Rings for Liner packing are also important. Liner Seal Rings is designed and made with hard corner which is an integral part of seal rings and soft nitrile element rubber center. We could provide reliable liner Seal Rings for our customers could order them at the same time.

All Lake Petro liner products are interchangeable with O.E.M. products. Meanwhile, we provide customized Liners according to drawings. Our liners, also with our other mud pump spares, are supplied for use in Honghua, F-Series, Bomco, Emsco and National lines of triplex drilling pumps. Let Lake Petro be your one-stop shop for your whole fleet of pumps. Please refer to “Suitable Pump Models” Lable for more details.

The RRP PINNACLE ASSEMBLED PISTON also known as Replaceable Rubber Piston or Supreme Piston is designed for use in the most demanding applications. The replaceable seal element is manufactured from a specially formulated elastomeric compound designed to be resistant to most chemical fluid found in the drilling industry today. These pistons can also be used in conditions where elevated temperatures can be problematic to other types of pistons in the market. The fabric anti-extrusion device on the piston is constructed from proprietary materials utilizing well researched process to reduce the extrusion of the rubber even at the pump’s maximum pressure rating.
