Reasons why the ammonia unloading pump/PAC discharge pump/chemical dosing pump fails to draw liquid

First, what is a magnetic pump? A magnetic pump consists of three parts: the pump, the magnetic drive, and the motor. The magnetic drive of the key component consists of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the electric motor drives the external magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, causing the internal magnetic rotor connected to the impeller to rotate synchronously. This enables contactless transmission of power, thereby converting a dynamic seal into a static seal. Since the pump shaft and internal magnetic rotor are completely enclosed by the pump body and isolation sleeve, the problems of leakage are resolved, eliminating the safety risks associated with the leakage of flammable, explosive, toxic, and harmful substances through the pump seals in the oil refining and chemical industry. Common reasons for no water discharge in acid- and alkali-resistant magnetic pumps and solutions: 1. Air in the suction pipe – refill with liquid or remove air from the pipe. 2. Leaks in the suction pipe – inspect the suction pipeline. 3. Insufficient liquid in the pump – refill it with liquid. 4. Pump running in reverse direction – adjust its rotation direction. 5. Excessively high suction height – lower the installation height
