Smooth Operation with Less Pressure Fluctuation
Our oilwell triplex pumps come from Hebei Zhongxin. Our factory started making mechanical parts in 1986. In 1996, we entered the drilling industry. Our factory covers more than 20 acres. We have over 30 years of experience. A triplex pump is smoother than a duplex pump. It has less pressure fluctuation. This pump is the F500 model. It is a horizontal three-cylinder single-acting piston pump. Its input power is 373 kW (500 HP). The rated stroke rate is 130 times per minute. The stroke length is 180 mm. The suction pipe diameter is 200 mm. The discharge pipe diameter is 83 mm. The total weight is 10680 kg. These oilwell triplex pumps are very good for oil extraction.


Complete Data Table for All Liner Sizes
You can use this pump for oil wells. It also works for natural gas wells and geothermal wells. We use it for high-pressure water and grout injection. Our products have gone to the Middle East, Africa, Russia, and South America. Customers say our triplex pumps work well and have a stable flow rate. Below is a table for liner diameter, flow rate, and pressure. Mechanical efficiency is 90%. Volumetric efficiency is 100%. Real data may have small differences.
