The requirements for pumping hydrocarbons in petrochemical plants and refineries are very high in terms of performance, efficiency, and emission limits. An increasing number of process pumps with magnetic couplings as per API 685 are being used here. For several years EagleBurgmann and KSB have been cooperating to design a magnetic coupling pump. The new zero-leakage RPHmdp refinery pump stands for the experiences of the KSB design engineers, EagleBurgmann's coordinated magnetic coupling program, and the combination of an existing pump hydraulic with the matching magnetic couplings.
The universal MAK modular concept for pumps – for initial installation or retrofitting – is based on two proven magnet variants, depending on the requirement: samarium-cobalt for operating temperatures up to 300 °C, and neodymium ferrum boron up to max. 120 °C. As a result, the coupling size can be optimally adapted to the required operating conditions and capacities.
Different containment shell materials with the least electrical conductivity for minimum eddy current losses are offered as well. A carbon fiber reinforced PEEK containment shell is used for applications up to 120 °C which eliminates completely eddy currents and seals with a maximum degree of efficiency. Due to the occurring loads, a metallic high-performance containment shell with a laminated structure, which reduces eddy current losses to a minimum, is used for more demanding applications up to 300 °C with higher speeds and pressures.
The magnetic couplings are supplied with high-precision sliding bearings to securely bear the pump shaft. The bearing absorbs the axial and radial forces of the impeller; an effective product circulation in the interior of the magnetic coupling ensures lubrication and heat dissipation and guarantees high operational safety – even for low-viscosity media. Bearings that can be cooled or heated are also optionally available. The gas from problematic gas-containing media is removed from the containment shell chamber by a hollow shaft which consequently prevents the risk of the sliding bearings from running dry.
