SETTIMA API676 Pump SMAPI series

 Screws can operate directly in the carbon steel housing, thus eliminating any expensive interior coating and additional housing. Instead of using flat washers, use only O-ring seals to avoid the risk of leakage. As the drive screw turns, fluid is transferred and continues to the pump outlet, creating a constant flow rate regardless of pumping pressure. This method of operation provides smooth, constant fluid flow, low noise, and high energy efficiency.
