On display for the first time at Achema 2009, last month, SLC-Series eccentric disc pumps (pohto) offer lower ongoing operations and maintenance costs in the transfer of various chemicals due to superior volumetric efficiencies. Unlike gear and lobe pumps that lose efficiency as they wear, SLC-Series pumps are designed to self-compensate for mechanical wear and maintain consistent flow over time. With sealless construction, the self-priming characteristics also boast the ability to run dry for up to five minutes. Other benefits include low shear and agitation of the pumped product, capability of handling solids and abrasives and clean-in-place capability. The line is available in stainless steel and ductile iron models capable of handling up to 10,000-cst (46,000-SSU) liquids and working pressures up to 130 psi (9 bar), depending on the model. — Mouvex-Blackmer, an operating company within Dover Corp.’s Pump Solutions Group, Auxerre, France
