Energy Cost Savings
By eliminating the need to increase the pump speed over time, sliding vane pumps save additional energy when compared to gear pumps. Sliding vane pumps are inherent energy savers by virtue of their design. This technology not only reduces energy costs but helps to create an overall more efficient pumping system. It provides solutions for seals, suction, product shear, and volumetric efficiency problems. It also offers unique benefits such as leak-free assurance, line stripping, metering, and non-pulsating flow, all while saving energy.
