Sanitary Metering and Transfer Pumps

Designed for low-shear sanitary pumping duties up to 35gpm (33l/min) and pressures up to 3.5 bar in the biotechnology, pharmaceutical and food industries, 800 series pumps feature a true CIP (clean-in-place) and SIP (steam-in-place) facility. The twin stainless steel rollers disengage to lift off the tube, allowing a straight-through path for cleaning. There are no "dead spots" or crevices. Mounted on a 304 stainless steel frame, 800 series pumps are available with fixed speed motor gearboxes, integral Varmeca inverter drives, or inverter-rated variable speed motor gearboxes providing 4-20mA or 0-10V process control, as well as remote stop/start and reverse. ATEX rated drives are also an option.
