With no magnets, no mechanical seals, and no packing— new SLP Seal-less Sliding Vane Pumps are introduced.
SLP25i, the initial model, offers a 110-gpm/25-m3/h maximum flow rate, up to 174-psi/12-bar differential pressure. It handles up to 278,000-ssu/60,000-cst viscosities and operates at up to 212°F./100°C.
SLP’s shaft is sealed by a double stainless steel bellows to eliminate the need for magnets, mechanical seals, and packing. The bellows covers an eccentric shaft that drives the bellows in a circular motion during pump operation. This motion rotates the pump shaft and rotor via integrated crank system. These design features are said to “make the pump 100% seal-less and leak-free.” SLP also offers up to 30% reduced energy consumption.
