I. Brief Introduction for RGF-Mud Pumps
RGF-mud pumps that RG Petro-machinery (Group) Co., Ltd has produced are the key equipment for the drilling/workover rig, which can be used for mud circulation.
RGF800¡¢RGF1000¡¢RGF1300 mud pumps are products designed and developed by RG Petro-machinery (Group) Co., Ltd itself by absorption of the advanced technologies from home and abroad. The parts of the RGF-mud pumps that are designed are in conformity with API SPEC 7K, which have been widely used in Chinese oilfields and already exported to U.S.A. European Nations, Middle East and Southeast Asian Countries.
II. Characteristics of the RGF -Mud Pumps
RGF- mud pumps have the following characteristics: an advanced and compact structure, miniature volume, good and reliable performance, which can meet the drilling requirements, such as high pumping pressure and big discharges.
RGF -mud pumps with a longer stroke can be used under the condition of low strokes to improve water supplying function of the mud pump and to prolong the working life for the easily-worn parts of the hydraulic end. The damper on the pump has a novel designed structure and a reliable performance, which cam make pump realize a best suction function.
The key parts, such as: hydraulic cylinder, crank. A-type grooved gear, etc are made of a special alloy steel and pump chassis and body is made of welded steel, which has a high intensity ,a good rigidity and light weight.
A good replacement performance can make the maintenance and the service of the RGF-mud pumps easy and convenient, especially, all of easily-worn parts on the hydraulic end can be freely substituted with the parts that can be in conformity with API Specs.
