DOLPHIN LT 0130–0220 A

Overview

The DOLPHIN LT 0130–0220 A are liquid ring vacuum pumps with proven two-stage construction and a corrosion-free stainless steel impeller. They feature a direct flange-mounted motor, an integrated flow channel and require no base frame. Housing materials are available in cast iron (EN-GJL-200) or 316 grade stainless steel and an ATEX-certified version is available (Cat 1G (i) 2G (o) IIC T4). The pumps are described as having extremely high vapor and particle tolerance, optimized gas flow, and the ability to use operating fluids other than water.
