Blackmer® MAGNES Series pumps bring world-first set of functionality, reliability, and flexibility to critical processes in numerous markets. As the newest addition to Magnetic Drive Line of sliding vane pumps, MAGNES Series Pumps are positive displacement rotary vane pumps that use a magnetic drive without dynamic seals. This self-priming magnetic drive pump provides a leak-free pumping solution for difficult to seal liquids and any liquids that are too expensive, valuable, dangerous or hazardous to leak.
With 3- and 4-in models available in both ductile iron (MI3, MI4) and stainless-steel (MS3, MS4) construction, MAGNES Rotary Vane Pumps boast performance up to 520 gpm at 200 psi (1,968 L/min at 13.8 bar). MAGNES Sliding Vane Pumps provide magnetic drive pump capabilities, with the innate advantages of sliding vane technology. As a true self-priming pump, it will not need to be pre-flooded prior to start-up and is well suited for continuous duty operation, since the pump has no cumulative dry run limit. With this rotary vane magnetic drive pump design, the Blackmer MAGNES Series has combined the leak-free benefits of a magnetic drive pump, with the numerous advantages of sliding vane technology - such as self-priming, line-stripping, product recovery, dry-run capability, solids handling, thin/thick viscosity flexibility, easy maintenance and 70% to 90% pump efficiencies.
Features and Benefits
Magnetic drive pump design is inherently leak-free
Non-metallic, proprietary composite containment shell that provides the coupling strength of a thin wall metallic shell and the reliability of an eddy-current-free design
Low speed operation – pumps operate at 10%-20% speed range of comparable options, while achieving the same flow and pressure outputs as other pumping technologies
Solids handling ability – with large flow path design, and low internal flow velocity, particulates up to 1/8 inch (3 mm) can pass through without issue
Designed for entrained vapor handling, low to zero NPSH required
True self-priming pump, does not require filling before start-up
Features suction lift capabilities that meet or exceed 25 ft (7.6 m) wet vacuum and 16 ft (4.9 m) dry vacuum
Full curve performance across the entire system range, without sensitivity to a BEP curve
Entire pump assemblies available with motor, gearbox, and baseplate
Advantages of sliding vane technology:
Self-adjusts for wear to sustain flow capacity throughout pump life
Excellent at self-priming, eliminates expensive priming systems
Extended dry-run capability, eliminates nuisance current monitoring systems
Sliding vane design provides sustained performance and trouble-free operation
Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
High suction lift and line-stripping capabilities
Low maintenance and low life-cycle costs, pumps are renewable and repairable
Solids handling, provided by large displacement and slow internal velocities
Thin to thick fluid viscosity flexibility, eliminates expensive heating systems
