Ideal for bakers, the OPTI-140 twin-piston pump offers continuous product handling that's gentler than traditional screw-type pumps and operates at a processing throughput of up to 14,000 lbs./hr., which is significantly faster than ram and shear technology. Engineered without metal-to-metal contact points, these pumps are low-maintenance and are designed with such features as a power-tilt hopper that makes cleaning rapid and easy.
