Pumps Catalogue

Product catalog summary

Operating Principle
The document outlines the operating principle of linear-motor-driven free piston pumps, which use an electro-magnet to move the piston, compressing a return spring and drawing air into the cylinder. When the magnet is de-energized, the spring pushes the piston back, expelling compressed air. This mechanism is applicable to both AC and DC models, with AC models using a silicon diode and DC models employing an inverter for current conversion.

Linear-motor-driven Free Piston Mechanism
This mechanism integrates the functions of a pump and motor into a single unit, driven by an electro-magnet and return spring, suitable for advanced industrial applications as air sources or vacuum units.

Key Design Features
The pumps include an overpressure control mechanism to prevent motor failure, a self-cooling design to manage internal temperature, and a compact integrated design combining motor and compressor functions.

Series Selection
The catalog lists various models for different applications, including AC and DC linear free piston compressors, vacuum pumps, diaphragm pumps, and blowers, with specifications such as rated pressure, maximum pressure, and free air displacement.
