CR MAG-M API Series
The separation of liquid chamber/atmosphere by means of an isolation shell is the best solution to pump aggressive, explosive and toxic liquids, hydrocarbons, heat transfer liquids and liquids difficult to seal. The hermetic sealless is the perfect answer to the chemical, pharmaceutical, oil & gas and petrochemical industry. A wide range of pumps covers the different performances.
General
M PUMPS CR MAG-M Magnetic drive pumps are sealless pumps.The static rear containment shell forms a closed system with hermetically sealed liquid end.
Applications
M PUMPS CR MAG-M Magnetic drive pumps are designed to improve people and plant safety. Especially when toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all these services rear containment shell replaces double mechanical seals with external fluid reservoires and all the required control devices. CR MAG-M pumps offer therefore exceptional benefi ts to the chemical, petrochemical and allied industries.
Leakproof
CR MAG-M pumps have no glands, no seals no valves. Contrary to sealed centrifugal pumps, the hermetic construction of the CR MAG-M mag drive pump ensures a safe and leak free operation. Even under heavy-duty applications the pumps are extremely reliable. The mag drive pumps have an extended choice of materials as
well as a wide variety in models. With its 100% zero leakage mag drive coupling the M PUMPS mag drives are your problem solvers in fluids and chemicals transfer.
Construction
M PUMPS CR MAG-M are a single stage volute casing pumps with closed impellers, back-pull-out design, with end suction and top discharge flange. Centerline legs are provided as standard for foot mounting on the base plate. Capacity and outer dimensions according to API 685 second edition.
Advantages M PUMPS CR MAG-M mag drive centrifugal pumps
• Zero leakage (100% leak free)
• No mechanical seals or packed glands
• No external fl ushing systems
• Ensure a clean and safe operating environment, highly efficient
• Increased Mean Time Between Maintenance
ATEX
M PUMPS CR MAG-M mag drive pumps can be supplied to meet the requirements of Directive 94/9/EC, with ATEX certifi cation II -/2 G cbk II C Tx for installation in potentially explosive atmospheres.
NPSH-Conditions
As the internal circulation from discharge tosuction, doesn’t rise the temperature in the pumped liquid the handling of boiling liquids is possible without an increase of NPSH-required.
Balanced thrust loads
The thrust loads of the closed impellers are totally balanced by back vanes. Minimum residual forces that act in suction fl ange direction, are beared by strong silicon carbide, spring mounted, thrust bearings.
Epoxy primer and polyacrylic enamel water-based painting for the best quality resistance linked to the environmental respect.
CF8M Pump Casing & Impeller High quality casting components.
Other materials:
– Hastelloy® C276,
– Incoloy® 825,
– Duplex,
– Titanium,
– Others materials available on request.
Field assembling of the product lubricated bearing arrangement does not require special tools.
The bearing materials available are of three different types to provide the best solution for each application: Silicon Carbide (SSIC), Tungsten Carbide (WC) and Special Carbon. The use of elastic rings reduces the sleeve bearing loads and the thrust bearing loads to a minimum, to guarantee many years of maintenance-free operation.
RWP QUICK CARTRIDGE KIT
to guarantee an easy and fast
maintenance.
Closed impeller statically and dynamically balanced. The axial thrusts are balanced by back vanes, for the best axial balancing independently from suction pressure.
Rear shell is made of one single piece, no welding, ellipsoidal profile that has been studied to withstand higher pressures than the traditional one. Hastelloy® C276 is standard isolation shell material – providing a safe and efficient solution – system pressure max 16 bar. Hybrid rear casing technology available for energy saving configuration. Titanium Alloy is an upgrade when higher pressure ratings and increased efficiency are required.
Double rear shell on request.
High power synchronous magnetic coupling designed by
our Technical Office and with rare earth magnetic elements
mechanically locked.
The high performance magnets can operate at liquid temperatures
of up to 662 °F (+350 °C) without external cooling. Transmittable
horsepower exceeds 520 kW / 700 HP.
