Magnetic Gear Pump

A magnetic gear pump is a volumetric gear pump that transmits torque contactlessly via a magnetic drive. It replaces dynamic seals with static ones, achieving a leak-proof state. The magnetic drive gear pump, with the pump shaft and internal magnetic rotor enclosed by the pump body and isolation sleeve, solves the issue of leakage commonly found in traditional pumps.

The pump's speed and flow rate are in a linear function relationship, allowing flow adjustment by changing the speed.

The following is a detailed introduction to magnetic gear pumps:

I. Product Overview
Magnetic gear pumps are ideal for various industries including oil, chemical, pharmaceutical, smelting, electroplating, environmental protection, food, and more. They are designed for transferring flammable, explosive, volatile, toxic, rare, and precious liquids, as well as various corrosive fluids. They are particularly suitable for transporting lubricating fluids that do not contain solid particles or fibers.
II. Structural Features
The Magnetic Gear Pump is primarily composed of several parts, including the gear pump head, magnetic drive, motor, and connecting base plate. The magnetic drive consists of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolating sleeve. As the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate through the air gap and non-magnetic materials, causing the inner magnetic rotor connected to the driving gear to rotate synchronously, achieving a contactless synchronous transmission of power.
Section 3: Product Features
No Leakage: The pump shaft and inner magnetic rotor are sealed by the pump housing and isolation sleeve, which solves the "running, spilling, dripping, and leaking" issues present in traditional pumps. This eliminates the safety hazards of leakage of flammable, explosive, toxic, and harmful media through pump seals.
Energy-saving: Magnetic gear pumps require no separate lubrication or cooling water, reducing energy consumption. Moreover, the transmission from coupling to synchronous traction eliminates contact and friction, resulting in lower power consumption, higher efficiency, and damping vibration effects. This reduces the impact of motor vibration on the pump and the effect of cavitation vibration on the motor.
Wide application range: Magnetic gear pumps can be made with different materials for bearings and pump bodies based on various media and operating conditions. For instance, stainless steel can be used in environments requiring high corrosion resistance or hygiene standards.
Overload Protection: In the event of overload operation or a seized rotor, the main and driven components of the magnetic drive will automatically slip, protecting the pump.
Section 4: Application Examples
Magnetic gear pumps are widely used in various industrial process flows, such as in oil refining, transporting corrosive liquids in chemical production, transferring liquid medications in the pharmaceutical industry, and circulating electrolytes in electroplating processes. Their leak-proof characteristics and broad applicability make magnetic gear pumps an indispensable piece of equipment in many industries.
5. Maintenance and Care
To ensure the long-term stable operation of the magnetic gear pump, regular maintenance and care are required. This includes inspecting the pump's sealing performance, bearing wear, flow of cooling lubricant, and motor operating status. Additionally, attention must be given to keeping the pump body clean and dry to prevent medium residue from causing corrosion or blockage. During shutdown maintenance, the pump body should be cleaned and maintained to extend the pump's lifespan and enhance its operational efficiency.
