On June 24, 2024, Wuxi Petrel successfully completed the installation and commissioning of its newly developed 5ZW120 high-pressure plunger pump at BAOSTEEL Group’s CSP line. The pump is now operating successfully and has demonstrated stable pressure output, reliable performance and strong operating efficiency. Its performance fully meets BAOSTEEL’s demanding technical and production requirements for high-pressure steel descaling.
The 5ZW120 is a heavy-duty quintuplex high-pressure plunger pump specifically developed for hydraulic descaling systems used in CSP steel plants, hot rolling mills and other steel production facilities.
Pump Model: 5ZW120
Pump Type: Quintuplex High-Pressure Plunger Pump
Pressure Range: 168–482 bar / 2,395–6,859 psi
Flow Rate Range: 432.04–2,086.93 L/min / 114.15–551.37 US gpm
Maximum Effective Power: 680 kW / approximately 912 hp
Application: High-Pressure Steel Descaling
Installation: BAOSTEEL CSP Production Line
Pumped Medium: Water
The 5ZW120 is the first domestically manufactured high-pressure plunger pump in China successfully applied to a CSP production-line descaling system. This achievement represents an important breakthrough in the localization of large-scale high-pressure descaling equipment for the Chinese steel industry. Our domestically manufactured descaling pump is able to provide reduced equipment procurement costs, shorter spare-parts delivery times and faster local technical support.

Company Profile
Petrel's foreign trade share takes around 50%. To meet standards and requirement of different foreign clients, Petrel continuously improve its production management.
Petrel improves product management system by ensuring the trackability of raw material sourcing, heat treatment process, and machining accuracy. The codes on key parts allow Petrel to track which steel mill supplies the material, which factory conducts the heat treatment, inspection records of fine machining, etc.
To sustain products' high quality, Petrel heavily invests its calibration lab by importing various inspection equipment, such as spectrometers, Brinell hardness gauges, coordinate measuring machine, etc.
To promote and sustain a high level of productivity and safety, Petrel also pays attention to employee training, which includes 6s lean methodology, instructions of equipment, standards, requirement of production process, etc.
