A new line of rotary-lobe pumps for the CPI
The recently launched EP series of positive-displacement rotary-lobe pumps (photo) was designed around the typical requirements of industrial pumping applications. The EP series handles extreme conditions and constant high pressures. A heavy-duty gearbox allows for a uniform pressure output of up to 260 psi (18 bars). These pumps consist of a one-piece housing that can reliably pump abrasive, chemically aggressive and explosive flow media at temperatures of up to 392°F (200°C). Helical gears in the gearbox ensure smooth performance and reduce noise emissions. Pulsation-free conveying reduces wear on the adjacent pipeline while providing a low-shear pumping action. The EP series is equipped with an AirGap for high operational reliability. The AirGap atmospherically separates the gearbox and pump chamber, ensuring that in the event of a leak, the liquid will drain off to the outside rather than leaking into the gearbox. The AirGap also protects the gearbox when pumping high-temperature media.— Vogelsang USA, Ravenna, Ohio
