Magnetic drive pump

Eermanent magnets for both the internal and external rotors, there is ss heat to the pumped fluid than with canned-motor pumps. Some canned-motor pumps have fully pressure-rated outer shells, which enclose the canned motor others don t. With magnetic-drive pumps, containment of leakage through the can to the outer shell can be a... [Pg.2309]

The Dow Chemical Company recommends canned-motor pumps or magnetic-drive pumps for phosgene service. Phosgene is an example of an extremely hazardous material. These pumps should have a secondary containment such that failure of the can does not create a phosgene release. The secondary containment should meet pipe specifications for pressure or relieve to the scrubber system in the plant. These pumps must have automated block valves on the suction and discharge. Operation of these valves should be managed such that the thermal expansion does not damage the pump. [Pg.2065]

Mixed flow pumps Incorporate the features of both axial flow pumps and radial flow pumps. Axial flow pumps operate on a vertical plane and radial flow pumps operate on a horizontal plane to the flow direction of water. Mud pumps Built to transfer heavy sludge or mud. Some larger versions are used to pressure. Th are sometimes used on oil rigs to pressurize and circulate fluid. Petrochemical pumps Made to transfer petroleum products that are often very viscous and corrosive. They can be magnetic drive pumps, diaphragm pumps, piston pumps, and others. [Pg.85]

Seal-less Fumps The most common maintenance problem with centrifugal pumps is with the seals. Seals can be essentially eliminated with seal-less pumps. Seal-less pumps are manufactured in two basic types canned motor and magnetic drive. Magnetic drive pumps have thicker cans, which hold in the process fluid and the clearances between the internal rotor and can are greater compared to canned motor pumps. Seal-less pumps are becoming very popular and are widely used in the chemical industry. Mechanical seal problems account for most of the pump repairs in a chemical plant, with bearing... [Pg.129]
