Abstract
Intermediate drives may provide containment for fluid handling devices, such as pumps. Such intermediate drivees may one or more utilize magnetic drives to provide static barriers for mechanical devices. A fluid handling assembly may include a fluid handling device comprising a housing, a housing cavity, a fluid inlet, and a fluid outlet. An intermediate drive may be positioned and configured to transmit energy from a motor to the fluid handling device while providing a secondary containment area that is separate from the primary containment area provided by the fluid handling device.
Claims20
A pump assembly comprising:
- a pump comprising a pump housing, a housing cavity, a fluid inlet, and a fluid outlet, the pump defining a primary containment area;
- an intermediate drive positioned and configured to transmit energy from a motor to the pump, the intermediate drive defining a secondary containment area separate from the primary containment area;
- a non-metallic first static barrier providing a static seal between the housing cavity of the pump and the secondary containment area;
- a non-metallic second static barrier providing a static seal between the secondary containment area and a surrounding environment;
- a first magnetic drive for providing a magnetic coupling across the first static barrier;
- and
- a second magnetic drive for providing a magnetic coupling across the second static barrier.
