Product: Mini Peristaltic Water Pump Model: SV3N40 Color: One Size Overview A compact, costeffective peristaltic pump designed for reliable transfer of both viscous and nonviscous liquids. Available for 12 V and 24 V systems with brush or brushless motor options. Suitable for laboratory dispensing, small scale food processing, filling and classification tasks where controlled, contamination liquid transfer is required. Key benefits Clean, noncontaminating fluid transfer because the liquid contacts only the pump tubing. Compact structure and plastic gear drive provide an economical solution where space and cost matter. Stable tube grip and synchronized rotor design prevent tube slippage and reduce maintenance. Multiple tube materials and sizes allow tuning of flow rate and chemical compatibility. Low vibration planetary gear transmission and 1 to 8 reduction improve torque conversion and pump stability. Basic specifications Voltage: 12 V or 24 V Motor options: Brush motor or Brushless motor Flow rate range: approximately 200 to 260 ml per minute (depends on tube selection) Operating temperature: 0 to 40 Celsius Model size: SV3N40 Tube selection and performance Materials and codes: Silicone S16: ID 3.2 mm x OD 6.4 mm Silicone S40: ID 4.0 mm x OD 7.2 mm Norprene N16: ID 3.2 mm x OD 6.4 mm Norprene N40: ID 4.0 mm x OD 7.2 mm Typical flow rates with 3 rotor configuration (ml per minute): S16: 210 S40: 260 N16: 200 N40: 260 Motor electrical data with 3 rotors: Brush motor 24 V: 0.4 A Brush motor 12 V: 0.8 A Brushless motor 24 V: 0.3 A Brushless motor 12 V: 0.6 A Mechanical and design features Pump body and pump head: smart snapin access for quick assembly and maintenance. Triangular synchronous disk fixed rotor: designed to keep rotors synchronized and prevent tube slippage. Threaded joint with selflocking fastening reduces air leakage and removes the need for additional hose clamps. Plastic gear drive offers costeffective transmission. Transmission mode: planetary gear transmission with a 1 to 8 reduction ratio for improved torque conversion. Pump tube options: Norprene or silicone compatible. Mounting plate options: through plate fixation or L plate installation. Tube compression stability rated less than 80 percent (operation dependent). Why choose this pump Flexible power and motor choices let you prioritize efficiency or lower current draw. Interchangeable tubing and predictable flow data simplify system integration and calibration. Simple mechanical design reduces maintenance time while maintaining reliable dosing performance. Compact footprint fits in constrained installations where a small, controllable liquid transfer solution is required. Practical use scenarios Laboratory experiment analysis: precise reagent dosing for small batch assays or continuous sampling. Filling and classification: automated filling of small containers, vials or cartridges where contamination must be avoided. Food processing: low flow dosing of flavorings, colorings or additives in small scale or bench production lines. Selection guidance Choose tube material based on fluid compatibility and required flexibility. S40 and N40 provide higher flow than S16 and N16. Select brushless motor for lower current draw at a given voltage, brush motor if specific drive characteristics are required. Confirm mounting plate choice and tubing size to match your fixture and desired flow. This mini peristaltic pump SV3N40 provides a compact, adaptable solution for controlled liquid transfer in laboratory, processing, and automated filling applications.
