Feature

●KPHM series peristaltic pump, the new design makes the pump tube is well fixed and prevents the pump tube from moving during operation. It is also a low-cost high flow peristaltic pump with high precision stepper motor.
●Motor: stepper motor. Voltage: 24V.Power：40W.Speed：300rpm，Pump tube size:6.4 mm ID x 11.4 mm OD.Flow rate: 100-900ml/min.Rotor: 3 rotors.Working Temperature: 0-40℃,Humidity: ＜80%,Pump head material: Nylon.
●Pump tube material: Pharmed BPT.Very good resistance to general chemicals, as well as excellent resistance to acids, alkalis and oxides.
●No pollution, low pulsation. The gearbox drives the pump tube to work, and the pump tube is not easy to slip.The liquid only touches the pump tube, not the pump body.
●Application: Experimental Research Experimental Monitoring，Inkjet.Printing，Aquarium，Smart Home，Aviation Operation.

Remark	The above parameters are measured with pure water without pressure under the standard atmospheric pressure at room temperature of 20°C. Actually, there will be certain errors in the flow rate according to different media, different outlet pressures, and DC motor speed errors. The data are only for reference. In addition, it can be customized according to customer needs.
Reference noise	In a quiet room with an ambient noise of 35dB, the product is 50cm away from the noise tester, and the noise is 55dB.

The bulls head shape design makes the peristaltic pump tube well fixed.

Flow speed curve

Note：Do not recommended directly adjust the speed to the highest for use, it will cause damage to the motor.

Because 400rpm is the limit of this product, we do not recommend to set the speed of this product to 400rpm for long term use. If you need to use it for a long time, we recommend to keep the speed at 350rpm, the super high load work may cause the product to be damaged prematurely.

Stepper Motor Parameters & Wiring

Note: Stepper motors need to be used with a driver board.

Driver board selection

MODBUS：Can be built-in and external potentiometer speed regulation, can be MODBUS RS485 communication and 0-10V analog speed regulation, realize two start and stop modes of electric and trigger, the maximum subdivision is 32, the drive current can be set (0.7A, 1.2A, 1.7 A, 2.2A, 2.7A, 2.9A, 3.2A, 4.0A)
