These corrosion-resistant process pumps with explosion-proof a.c. motors (photo) offer safe solutions for gas and liquid handling in potentially hazardous locations. These pumps are compliant with Class 1, Division 1, Groups C & D and ATEX hazardous locations. They offer high performance and long service life during continuous, heavy-duty operation, according to the manufacturer. Explosion-proof process pumps are typically specified to evacuate, transfer, compress or recirculate air, gases or vapors in demanding applications. In a series of several units. these compact pumps in can achieve flowrates up to 220 L/min and vacuums up to 29.86 in. Hg, depending on the model. All are designed to minimize power requirements and reduce costs; perform oil-free to eliminate media contamination and lubrication-related maintenance; run without wear-prone sliding seals; and incorporate quality precision ball bearings for optimized reliability. — KNF Neuberger, Inc., Trenton, N.J.
