KPHM400 / Kphm400b25 400 ml/min Peristaltic Pump with 24V Stepper Motor Why this pump matters Reliable metering and transfer: Delivers up to 400 ml/min for consistent small‑volume dosing, circulation and suction tasks. Low maintenance and contamination‑ fluid path: As a peristaltic pump, the pumped media only contact the tubing, simplifying cleaning and reducing cross‑contamination. DIY and integration friendly: Designed for hobby, prototype and small system use with a 24V stepper motor for precise speed control and easy automation. Key features and attributes Model: KPHM400 (also referenced as Kphm400b25) Flow rate: Up to 400 ml/min Pump type: Peristaltic (tube‑based pumping) Motor: 24V Stepper Motor included Functionality: Self‑priming; suitable for circulation and suction (small pump) Application focus: DIY peristaltic liquid pump for projects and small systems Compatibility: Intended for 24V power systems and stepper motor drivers/controllers for speed and flow control Maintenance: Replaceable tubing (peristaltic design keeps pump head isolated from fluid) Benefits for customers Precise flow control: Stepper motor drive lets you control speed and therefore flow rate for repeatable dosing or circulation. Self‑priming and suction capable: Starts pumping without manual priming in typical small‑system setups, simplifying installation and operation. Compact, small‑system fit: Suited to benchtop, chassis or enclosure mounting where space is limited. Versatile use: Works with a wide range of clear or colored liquids when compatible tubing is selected. Typical use cases Laboratory dosing and reagent transfer: Accurate small‑volume dispensing and circulation for experiments, sample prep or reagent delivery. Aquarium or hydroponics systems: Controlled circulation, nutrient dosing or water transfer in small aquaria and plant systems. DIY automation and hobby projects: Ink, coolant or chemical transfer, custom dispensers and prototype fluid systems where controlled flow and contamination control are important. Installation and operation notes Requires a 24V power supply and a compatible stepper motor driver or controller to manage speed and direction. Select tubing compatible with your fluid (tubing material is the wetted component in peristaltic pumps). Follow appropriate wiring and safety practices for the 24V stepper motor and control electronics. What's included (as described) KPHM400 peristaltic pump (model Kphm400b25) with 24V stepper motor. Technical reminder Flow performance is specified as 400 ml/min under typical conditions; actual flow depends on tubing, speed and system backpressure.
