MATERIALS HANDLING
vane pumps have the robustness and fl exibility to handle multiple changing fl uid and system conditions. In other words, vane technology provides the fl exibility to operate across the full system range of chemical- transfer systems. T ey also boast zero leakage. T e containment shell is the foundation of a pump’s leak- free capabilities. T is magnetic-drive sliding vane pump’s shell is unlike any currently available, as it off ers dry run, unmatched pressure containment, maximum coupling rating and leak-free operation. T e metallic shells in competitive technologies have thin walls that maximise coupling strength; however, these competing metallic shells produce eddy-currents that generate heat and limit pump reliability. Some competing non- metallic shells do avoid eddy-current heat
issues; however, these competing non-metallic shells use unreinforced polymers or
short carbon-
fi bre enforcement. As such, these competing shells
The Blackmer Magnes series magnetic-drive sliding vane pump
produces a combination of fl exibility, functionality and reliability that solves legacy operating pain points
require greater wall thickness that reduces coupling strength. In contrast, this magnetic- drive sliding vane pump’s containment shells use a proprietary
design and production process. T e shell is constructed of long carbon fi bres embedded in polyether ether ketone (PEEK). T is gives the containment shell the coupling strength of a thin-wall shell and the reliability of being eddy-current-free. T e optional close-coupled drive design enables quick and easy system set-up, eliminating time-consuming alignment processes And with suction-lift capability exceeding 25ft, sliding vane pumps off er

new functionality, reduce additional system operating costs and enhance safety for all operators by eliminating the need to pre- prime the system.
CONCLUSION T e evolution of the seal-less leak-free sliding vane pump has reached its next level with the development of the Magnes series. T is advanced pump technology eliminates the pervasive pain points of legacy centrifugal and gear pumps in chemical-transfer applications. Namely, it has indefi nite dry-run capability, solids handling, operates well with cavitation and vapour mixtures, and off ers full curve and system performance. Combine these features with a new, seal-less magnetic- drive design and today’s chemical manufacturers have an innovative new option when searching for the best pump to deploy in their critical and severe-duty operations.
