Introduction
•This series of products consists of three models: B250K1KT15, B250K2KT15, and B250K3KT15;
•External analog quantity to adjust the speed, analog quantity 0-5V/0-10V/4-20mA.
•External signal controls start and stop, forward and reverse rotating, external control signal 12-24V wide range input, optoelectronic isolation.
•The unique design of the spring roller body allows it to adapt flexibly to hoses of varying wall thicknesses, ensuring longer tube lifespan and making installation a breeze;
•The pump head is strong, tough, and highly resistant to chemical corrosion;
•Operates stably and quietly, with a semi-transparent shell that allows for real-time observation of its internal workings;
•Used in medium traffic environments;
•Suitable for use with devices, instruments, and laboratory setups.
•Ideal for integration with OEM systems.

•The above flow data were all tested using a Lead Fluid silicone tube to pump pure water under laboratory conditions with normal temperature and pressure. This data is for reference only.
•Due to pressure in actual use , temperature, medium characteristics, tube material and other specific factors, the specific situation needs to consult our engineers.
Head Pump Structure
Component name and function:
1.Pump head: Install tubes to transfer liquids.
2.Mounting Plate: This component connects the motor to the pump head and allows the product to be installed onto other devices.
3.Motor: Provides power.
4.The drive control unit: manages the stepper motor’s speed and start/stop settings.
