The D-D P1-STP Connect is an intelligent, app-controlled stepper-motor peristaltic pump built for continuous 24/7 duty. With Wi-Fi connectivity, it can be controlled directly from a mobile device or integrated into a wireless network, making it ideal for automated dosing and controlled-flow applications.

Unlike standard on/off feed pumps, the P1-STP Connect uses a direct-drive stepper motor to deliver smooth, constant flow. This makes it particularly well suited to applications where stability is critical — most commonly supplying a calcium reactor or nitrate reactor, where a steady, uninterrupted feed rate is essential for consistent reactor performance.

The ability to fine-tune flow rate and maintain continuous output also makes the pump ideal for reagent delivery and other systems that depend on predictable, long-term flow rather than intermittent dosing.
