Leak-Free, Magnetic Drive Pump Featuring Positive Displacement Sliding Vane Technology
________________________________________________________________________________________________________________________
Blackmer® MAGNES Series Magnetic Drive Pumps bring world-first set of functionality, reliability, and flexibility to critical processes in numerous markets. As the newest addition to Magnetic Drive Pump Line of sliding vane pumps, MAGNES Series Magnetic Drive 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.
MAGNES Series Magnetic Drive Pumps solve legacy pain points with technically superior functionality that’s designed for chemical and severe duty applications. Key attributes include:
- Indefinite Dry Run
- Solids Handling
- Cavitation & Vapor Mixtures Handling, Low to Zero NPSHr
- Full Curve & System Performance

With 3- and 4-in models available in both ductile iron (MI3, MI4) and stainless-steel (MS3, MS4) construction, MAGNES Magnetic Drive 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
