Granzon PWM DDC-Style Pump with Digital Display

The Granzon PWM DDC-style pump combines compact performance with a modern digital interface for complete control and monitoring. At the heart of the design is a tachometer-style gauge showing the pump’s real-time rotational speed. You can adjust the speed manually in steps of 100 RPM, or switch to automatic mode via the PWM signal from your motherboard.

The display also provides simulated flow rate, voltage, and load, giving you a clear overview of pump operation. Note that the flow rate is calculated based on the current RPM — the lower the loop resistance, the more precise the simulation. In most setups, this will be an accurate representation of actual flow.

The pump comes ready to install, enclosed in a durable POM housing. The top features G1/4" threading, making it easy to attach a reservoir if desired.
