Blackmer introduces MAGNES series sliding vane magnetic drive pumps

Technology

Blackmer, a Dover company and a global leader in speciality pumps and reciprocating compressor technologies, has introduced its new MAGNES Series Sliding Vane Magnetic Drive Pumps

Blackmer MAGNES Series pumps are the latest advances in seal-less magnetic drive technology and incorporate innovative design features that result in pumps that combine flexibility, functionality and reliability to resolve legacy operating pain points – including unexpected dry run, pumping fluids with solids, handling of fluids with entrained vapours and poor inlet conditions, and inflexible pump operating range – while also delivering technically superior handling of hazardous chemicals in severe-duty applications.

Blackmer MAGNES Series pumps are positive displacement rotary vane pumps that use a magnetic drive without dynamic seals, providing a leak-free pumping solution for difficult-to-seal, expensive, valuable, dangerous and hazardous liquids. With this rotary vane magnetic drive pump design, these pumps combine the leak-free benefits of a magnetic drive pump with the numerous advantages of sliding vane technology – including self-priming, line-stripping, product recovery, indefinite dry-run capability, solids handling, thin/thick viscosity flexibility, easy maintenance, low to zero NPSHr, 70 per cent to 90 per cent pump efficiencies, and full-curve operational flexibility.

MAGNES Series pumps are available in a 3-inch model (a 4-inch model will be available in January 2021) in ductile iron and stainless steel construction and feature a non-metallic, proprietary composite containment shell that provides the coupling strength of a thin metallic wall shell and the reliability of an eddy-current-free design.

MAGNES Series magnetic drive pumps have the robustness and flexibility to handle multiple changing fluid and system conditions, unlike alternative pump options that must be tuned to a single BEP. MAGNES pumps are available with an optional close-coupled drive design that allows fast and easy system setup, eliminating time-consuming processes of alignment.
