POSITIVE HYDRAULIC DISPLACEMENT PUMP WITH MAGNETIC DRIVE

摘要

The present invention relates to a device that converts mechanical energy provided by a generator of external movement into hydraulic energy. This energy is used to displace a fluid through a pipe connected to flanges of the pump. The pump can be used in different areas in industry, such as the pharmaceutical, food, biomedical, agriculture, mechanical, construction, transport and mining industries, etc.This is because of its versatility for transferring mechanical energy to fluids of different viscosities, with dosing proportional to the angular displacement of the drive shaft. The movement of the movement generator is transferred inside the device by means of a rotor shaft with a single arrangement of magnetic elements provided with magnetic shields. The pump solves the technical problems involved in the use of mechanical seals, such as: contamination of working fluid; mechanical seal failure because of shaft misalignment, causing leaks; and mechanical seal failure because of contact face breakage, causing the fluid to leak to the exterior.
