Pumps Sliding Vane Magnetic Drive Pumps
Blackmer has announced the availability of its new Magnes Series Sliding Vane Magnetic Drive Pumps. The 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.
The latest advancement in seal-less magnetic drive technology, the new Series pumps incorporate innovative design features that result in the world’s first pumps that produce a combination of flexibility, functionality and reliability to solve 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.
The 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, states the firm. 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 % to 90 % pump efficiencies, and full-curve operational flexibility, adds the company.
Available in a 3-inch model (a 4-inch model will be available in January 2021) in both ductile iron and stainless-steel construction, the Series pumps feature a 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. According to the firm, unlike alternate pump options that must be tuned to a single BEP, the Series magnetic drive pumps have the robustness and flexibility to handle multiple changing fluid and system conditions. The pumps are available with an optional close-coupled drive design that enables quick and easy system setup, eliminating time-consuming alignment processes.
