Measures for Leakage Prevention of Engineering Plastic Magnetic Pump
2023-01-24

Engineering plastic magnetic pump is a new type of pump that utilizes the working principle of permanent magnet couplings to transmit torque without contact. When the prime mover drives the outer magnetic steel to rotate, the magnetic field drives the inner magnetic steel rotor to rotate synchronously, and the inner magnetic steel rotor and impeller are connected together, achieving the goal of non-contact driving the impeller to rotate. Due to the liquid being enclosed in a stationary isolation sleeve, the magnetic pump is a fully enclosed and leak free product, completely preventing the inevitable problems of running, emitting, dripping, and leaking in mechanical sealed centrifugal pumps.

Leakage free chemical pumps are our goal and mission. Our strict quality requirements for engineering plastic magnetic pumps have led to more customers choosing us.

1. The sealing material for acid and alkali resistant pumps is generally fluorine rubber, and in special cases, polytetrafluoro material is only used; The material configuration of the mechanical seal message ring is relatively pivotal, and it is not treated differently based on the characteristics of the medium, rather than hard alloy. For dynamic sealed chemical pumps, packing seals are rarely used, mainly mechanical seals. Mechanical seals can be divided into single and double end faces, balanced and non balanced types. Balanced types are commonly used for sealing pressure media (usually referring to pressures greater than 1.0MPa). Double end mechanical seals are mainly used for warm, crystallized, viscous, spiky, and toxic volatile media. Double end mechanical seals should inject isolation liquid into the sealing chamber, Its pressure is generally 0.07-0.1MPa higher than the medium pressure.

2. Sealing form of engineering plastic magnetic drive pump: For static sealing, there are usually only two forms: sealing gasket and sealing ring. The viscosity of the medium has a significant impact on the performance of chemical pumps. As the viscosity increases, the head curve of the pump decreases, and the head and flow rate of the operating conditions also decrease, while the power increases and the efficiency decreases. The parameters on the general samples are the functions of water purification, and conversion shall be performed when transporting viscous media. For the slurry, paste and viscous liquid with higher viscosity, it is recommended to use screw pump.
