LMP screw pumps for delivery pressures up to 120 bar

Primary areas of use

• Machine tools
• Machining centers
• Central and decentralized coolant and preparation systems
• Booster stations
• Lubricant and hydraulic units
• Among other things

Due to its wear-resistant design, the LMP series is especially suitable for:

• Demanding applications involved in processing difficult to mill materials such as aluminium and stainless steel
• Various precision applications such as in the aerospace industry
• Grinding applications

LMP screw pumps with frequency converters

An LMP pump with integrated frequency converter enables optimum usage depending on the application. It adjusts the electrical output to the application's requirements and thus saves energy. Adjustment can be made to various operating points in the characteristics field to configure the pump ideally for the area of application. This adjustment can be made either smoothly or with defined increments as required. If needed, a single pump with a frequency converter can be used to accomplish the tasks of several pumps (without speed adjustment). Full separation of the motor from the pump allows integration of the speed adjustable operation for retrofitters as well.

Advantages

• Huge output range
• Optimum adjustment to the respective machining process
• Universal adjustability of the pump speed through all pressure ranges
• Frequency converters work almost no loss and are entirely maintenance-free
• Regardless of voltage fluctuation in the power supply
• Speed adjustment ensures effective delivery rate and usage
• Economically convincing, energy efficient alternative to standard solutions
• High dependability
• Long service life
• Quick and simple commissioning
• Convenient integration in machine control
• Compact design
