General
Magnetic coupled DICKOW-pumps of the series PRM according to API 685 are heavy duty sealless pumps. The containment shell forms a closed system to separate the pumped liquid from the atmosphere by confined gaskets. The equipment (including auxiliaries) is designed and constructed for a minimum service life of 20 years (excluding normal wear parts) and an uninterrupted operation of at least 3 years.

Applications
Magnetic coupled PRM-pumps improve plant and personnel safety and reduce maintenance costs, because 90% of these costs are caused by lea king seals. The PRM-pumps will handle nearly all kinds of liquids in the chemical and petrochemical industry, in refineries and industrial heating plants. Especially liquids which are toxic, flammable, bad smelling or which react on contact with the atmosphere, that means if no leakage is acceptable. For all these services the containment shell replaces the double acting mechanical seal with its external flushing system and the related control equipment. The performance range of the PRM-pumps is subdivided such that the best efficiency is guaranteed for all service conditions. The capacity goes up to 900 m3/h (4000 USgpm), the differential head up to 150 mLC (500 ft).

General
The DICKOW pump series KM are sealless centrifugal pumps. The static containment shell forms a closed system with hermetically sealed liquid end.  Model AMB pumps match ANSI casing dimensions.

Applications
Magnetic driven KM-pumps are designed to improve plant and personnel safety. Especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. The KM-pumps operate maintenance-free and their containment shells replace double acting mechanical seals, along with external fluid reservoirs and the necessary control equipment.
Maximum capacity appr. 70 m3/h (300 US-gpm), differential head 65 mLC (213 ft). Temperature range -30°C to 200°C (390°F), working pressure 16 bar (232 psi).

General
Magnetic coupled DICKOW-Pumps of series NMB/NML are of sealless design. The containment shell forms a closed system with hermetically sealed liquid end.

Applications
Magnetic driven NM-pumps are designed to improve plant and personnel safety, especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all these services the containment shell replaces double acting mechanical seals, along with external fluid reservoirs and the necessary control equipment. NM-pumps therefore offer exceptional benefits to the chemical, petrochemical and allied industries and fulfill all environment protection regulations.
Maximum operating temperature 240°C (465°F) for the standard NMB/NML-type. The maximum allowable working pressure is 25 bar (364 psi).

General
Magnetic coupled DICKOW-Pumps of series NMR are of sealless design. The containment shell forms a closed system with hermetically sealed liquid end. The NMR are designed for the chemical process industry. A leak-free magnetic drive is used to improve plant and personnel safety in industrial heating plants.

Applications
Magnetic driven NMR-pumps are designed to improve plant and personal safety, especially when handling toxic, explosive or other dangerous liquids which react with the atmoshpere. For all these services the containment shell replaces double acting mechanical seals with external fluid reservoirs and the necessary control equipment. NMR-Pumps therefore offer exceptional benefits to the chemical, petrochemical and allied industries and fulfill all environment protection rules.
