Ampco QTS Twin Screw Pump

The Ampco QTS twin screw pump conforms to 3-A Sanitary Standards design criteria, is clean-in-place (CIP) capable, and made of 316L stainless steel. The QTS is capable of bidirectional flow and is able to reach speeds up to 3000 rpm. These capabilities allow the pump to perform both processing and CIP using the same unit. The QTS moves soft solids delicately, without damaging the product or compromising visual integrity.

Capable of reaching high suction rates, the QTS twin screw pump is self-priming, and the low net positive suction head (NPSH) is the perfect solution for tank emptying. The QTS handles up to 60% entrained air, reducing cavitation and allowing for constant gentle product flow even at high speeds.
