Lefoo 115VAC Demand Delivery Pump

LEFOO demand delivery pump is a type of diaphragm volumetric pump. The diaphragm plays a sealing and protective role in isolating the transmission medium and the power end (motor). At the same time, the regular movement of the diaphragm changes the volume of the working chamber, thereby sucking in and discharging liquid, and achieving liquid dispersion. Conveying and pressurizing. The pump head is equipped with a microswitch through the valve plate, and the microswitch and the motor end form a series connection. When the pressure increases, the valve plate deforms under the action of pressure, triggering the micro switch to cut off power; when the pressure decreases, the valve plate resumes its deformation, and the micro switch resumes power, thereby realizing automatic start and stop.

Features of 115VAC Demand Delivery Pump

Automatic start and stop: high-voltage power outage and low-voltage start-up are possible;

Multiple pressure disconnect points: adjustable pressure range is 30-100PSI;

High self-priming capacity: self-priming height ≥ 2 meters, the suction chamber and discharge chamber are three-chamber independent structures, with high stability;

High-performance motor: all-copper motor, strong power, low temperature rise, and can work continuously;

Low electromagnetic noise and vibration: The motor adopts an integrated magnetization process, which has lower electromagnetic noise and vibration;

Smooth water flow: The water outlet adopts a buffer structure design, which has lower water flow pulse and vibration;

Anti-return function: anti-return structural design to prevent medium backflow;

Overheating protection: Equipped with a thermal protector, if the pump shell temperature is higher than 77°C, it can automatically stop working;

Integrated backflow pressure relief device: bypasses backflow to reduce frequent starts and stops of the pressure switch;

High waterproof performance: full range IPX5;

High stability: stable output and disconnection pressure, long life;

High strength: pressure-bearing parts are reinforced nylon and aluminum alloy;

Process-based: Full inspection and control of electrical, sealing, pressurizing and other performance production processes;

Authoritative certification: ROSH, CE, CQC, REACH certification;
