4-Web Valve Assembly for Mud Pump
The key feature of the 4-web, center-guided valve is the preloaded urethane insert secured with a threaded retainer plate with knock-off lugs for easy disassembly. This design enables drillers to change valve inserts quickly and minimizes downtime. The valve is best suited for low- to medium-pressure drilling operations because of the two-piece assembly of the valve body. The center-guided design enables the valve flange to be supported under pressure loads by the top of the center-support webs in addition to the seating taper on the inside of the valve seat. This allows for a large bearing area for the valve that minimizes stress and promotes a long service life. Our standard valve is offered with urethane inserts rated for 170° to 180°F drilling-mud temperatures. We also offer a special high-temperature urethane compound as an option for high-temperature drilling conditions to 200°F and higher.

Ceramic Zirconia Liners for Mud Pump
OFD Zirconia-ceramic liner is our premium liner product offering. It offers unmatched durability and promotes the longest piston life in the most demanding drilling conditions. Effectively impervious to heat, pressure, and corrosion, it is the ultimate in liner technology that is available today. While initial costs are higher than traditional chrome-iron liners, the durability of the liner and the longer run times it promotes on pistons translates into lower overall ownership costs and reduced risk of exposure for the driller. OFD Zirconia-ceramic liner is produced from a unique zirconium based ceramic compound that is extremely pure and has been stabilized by the addition of magnesia (Mg) to the matrix. This process promotes a tough, fine-grain structure that is free of the voids and impurities that affect lesser products. No other ceramic-liner material has better fraction toughness, which enables Best to offer a ceramic liner that is hard and long lasting, tough, crack resistant, and not susceptible to thermal shock.

Rod System complete for 12-P-160 5000 PSI New Style – Pt.No.33000000
OFD realizes Complete Rod System Pt.No.33000000 for National Mud Pump 12-P-160 5000 PSI New Style. The construction of all the details of the Rod Systems begins with the acquisition of raw materials, from which are then derived all finished components by means of tooling machines. These components are then assembled at our assembly department to get the Rod System finished. We are also be able to supply all the components separately Rod System that we realize, even as Spare Parts. Each single detail that makes up the Rod System, undergoes a heat treatment to improve the wear resistance and to increase durability in time. To ensure the ultimate suitability of each product, after each processing stage we carry out strict dimensional inspections.
