Electric Peristaltic Dosing Pump 110V240V with Adjustable Flow 4120ml/min SelfPriming Low Noise for Aquarium Lab

Product overview This electric selfpriming pump features a reflux valve design that keeps fluid circulating inside the pump if the outlet becomes blocked. The motor continues running while the reflux valve opens to liquid internally, preventing flow interruption and reducing the risk of damage from back pressure. Key benefits Continuous protection: Reflux valve allows internal recirculation when the outlet is blocked, avoiding repeated starts and stops and protecting the pump. Flexible power compatibility: Operates on 110VAC to 240VAC, suitable for a wide range of electrical systems. Selfpriming convenience: Eliminates the need for manual priming before operation, saving setup time. Quiet operation: Designed for low noise in the workplace. Wide flow capacity: Available flow ranges accommodate both low and volume transfer needs, helping improve process conversion rates. Important specifications Size / Voltage: 110VAC240VAC Color: 9 to 53 Ml Per Min Fuel / Power: Electric Structure: SelfPriming Pump Flow rate options: 4 ml/min to 18 ml/min; 9 ml/min to 53 ml/min Design feature: Reflux valve for internal recirculation when outlet is blocked How it solves common problems Blocked outlet scenarios: Instead of forcing the motor to stall or risk damage, the reflux valve opens and allows fluid to circulate inside the pump while the motor continues to run. Priming and startup delays: Selfpriming design reduces manual intervention and speeds up commissioning. Noise concerns in work areas: Lownoise operation makes it suitable for environments where reduced sound is important. Typical applications Sewage sampling and collection where reliable, continuous operation is required even if discharge lines become clogged. Largevolume liquid transfer in industrial or process settings that need flexible flow options and minimal downtime. Circulation or dosing tasks in water treatment, laboratories, or production lines where selfpriming and low noise are valued. What to consider before Confirm the required flow range for your application and select the appropriate model between the available flow rate options. Verify supply voltage compatibility within the 110VAC to 240VAC range. Ensure the pump materials and wetted parts are compatible with the liquid being handled. This pump is a practical choice when you need an electric, selfpriming unit with reflux protection, quiet operation, and selectable flow capacities for sewage sampling, liquid transfer, or circulation tasks.
