Oil & Gas
You can rely on 60 years of experience in the construction of pumps, packages, skids, and systems for onshore and offshore oil and gas production. Take a look at the information now!
LEWA high-pressure plunger pumps are primarily used in the oil, gas, petrochemicals and refineries industries. They work against high pressures that occur when pumping and conditioning crude oil and natural gas.
Our high-pressure pumps are robust, quiet, efficient, cost-saving and, thanks to their double-helical gear unit, practically free of axial load. Their space and weight-saving design makes them ideally suited for offshore applications, such as on drilling platforms.
We analyze the requirements for each application and configure the pumps according to all of our customers' specifications. We provide a flexible selection of materials, special offshore designs and painting according to customer specifications. In addition, we supply accessories designed for the specific application, e.g. pulsation dampers or safety valves in accordance with ASME and API standards.
LEWA high-pressure plunger pumps are plunger pumps with an integrated gear unit in a monoblock design that offer numerous advantages in relation to comparable pumps.
The integrated gear unit with double-helical gearing enables very compact construction and maximum efficiency. This results in a small footprint accompanied by low energy consumption. A special plunger and cross head alignment contribute to the space-saving design.
The gear unit is monitored by temperature and pressure switch/transmitter. This protects the pumps from a low oil level and overloading.
Double-helical gearing keeps the crankshaft and the pinion shaft free of any axial loads. This results in a longer service life and means less noise is generated in the plunger pump thanks to the even transmission of force.
Crosshead pins and connecting rod bearings are supplied by an integrated pressurized oil lubrication system depening on design scale. No additional lubrication systems with additional monitoring and wiring is necessary. The lubricating oil does not have to be drained for maintenance.
LEWA plunger pumps fulfill the internationally valid quality standard of the American Petroleum Institute API 674. This standard defines all requirements for a displacement pump in industrial settings with respect to design, construction and performance. We would be happy to provide you with any additional certifications.
