Other Mud Pump Parts

The 2S gear oil pump is the main element for the lubricating system of the power end for mud pump. This lubricating oil pump is usually installed on the pressure lubrication system, offering lubricating oil for crosshead, crosshead bearing, extension rod, etc.

The corrugated bellow is a kind of tubular elastic rubber product which is connected using a corrugated piece for the mud pump from LANSHI and QINGSHI factories. It plays a role in separating and sealing between the fluid end and the power end of a mud pump. Dezhou Rundong Petroleum Machinery Co., Ltd. is capable of producing different models of corrugated pipes. Our company holds an independent rubber accessory factory and the first self-invented rubber injection machine in China. After injection, the raw material can be vulcanized and completed in an integrated mould for only once, which ensures both performance and lifespan of the corrugated bellow.

The plug is an important part for the fluid end of mud pump in oil drilling. Its front part is equipped with cylinder head (valve cover) sealing ring for the sealing and pressure maintaining of a hydraulic cylinder. A top-grade suitable plug is adopted to improve the cylinder head plug loading condition and also increase the bearing capacity and service life. Plugs made by RUNDONG Company cover a full range of pumps from BAOSHI, LANSHI and QINGSHI factories. All of them adopt high quality alloy carbon steel made by domestic steel plants. They are finished by means of high temperature forging, heat treatment and CNC machining so as to achieve guaranteed geometric size, sealing performance, increased durability and wear resistance.

The locking clip is a part of the fluid end of F series mud pump from BAOSHI factory. It has the function of fixing and supporting the guide inside a hydraulic cylinder. The product produced by RUNDONG Company is made from superior quality brass. After being heated, it is bended and completed with specialized equipment for increased wear resistance and extended service life.

The stuffing box is an important component for the power end of mud pump in oil drilling. It plays a crucial part in sealing the lubricating system and the operation inside power end. Its housing produced by RUNDONG Company is precisely cast from ductile cast iron beyond industrial standard for improved mechanical properties and elongation. The adoption of heat treatment and phosphating technology helps eliminate the internal stress generated from the casting process and also improves corrosion resistance. After CNC finish machining, it is tightly assembled with wear-resistant rubber, vulcanized oil seal and sealing ring, as well as the nylon oil seal ring made by the machining center. In this way, the service life of sealing elements inside the stuffing box assembly could be greatly extended. This product is well received by clients.

As its name implies, the cylinder retaining ring is a part of fluid end for fixing the cylinder sleeve.

The cylinder head plug is a vital part for the fluid end of mud pump in petroleum drilling. A high quality suitable plug is adopted for improved loading condition as well as increased bearing capacity and lifespan. The product made by RUNDONG Company covers a full range of BAOSHI, LIANSHI and QINGSHI brand pumps. It is derived from top grade alloy carbon steel made by domestic steel plants. Besides, this product is completed with high temperature forging, heat treatment and CNC machining technology so as to guarantee the geometric size, sealing performance as well as increased durability and abrasion resistance.

The piston rod nut is a kind of anti-loosening nut for the end of piston rod. In common with the material of piston rod, it is made from superior quality alloy steel. The head of the product manufactured by RUNDONG Company is filled with a wear-resistant high strength nylon gasket so as to prevent rod thread from abrasion or being impacted by mud when in use of a piston rod. After heat treatment, this product offers better mechanical property. All models of piston rod nuts in metric and imperial units from BAOSHI, LANSHI, QINGSHI and other factories can be produced to meet the needs of customers.

The discharge filter screen assembly is a main component of the outlet for the fluid end of mud pump in petroleum drilling. It is composed of filter screen assembly, housing assembling as well as sealing ring, end cover and other accessories. The integrated formed filter screen housing made by our company adopts casting technique. The filter screen assembly is manufactured from superior quality alloy steel and assembled after CNC machining. This not only provides excellent corrosion resistance and pressure resistance, but also helps customers increase production efficiency.
