Cheng Yu-Pump Chemical Pump Introduction: energy efficient pumps chemical pump is the joint design, performance, technical requirements of the pump, according to the performance and size of the design under the international standard ISO2858, and its advantages: full range of water conservancy performance rational layout, the user selects Wide range, "after open" structure, easy maintenance, efficiency and suction lift up to international advanced level. Chemical pumps Category: stainless steel chemical pumps, plastic chemical pump, fluorine plastic chemical pumps, chemical pumps of various sizes impeller electric, pneumatic chemical pumps. Chemical pump seal in the form are: oil seal, gasket seal, threaded seals, labyrinth seals, packing and dynamic seals, mechanical seals. Oil seal is a self-tight lip seals, simple structure, small size, low cost, easy maintenance, less torque resistance, both to prevent media leaks, but also to prevent external intrusion of dust and other harmful substances, but also for wear a certain ability to compensate impeller, but impatience high pressure, it is generally used in low pressure situations of chemical pumps. Gaskets gaskets are basic components of the centrifugal pump static sealing, using a wide range. Spacer main selection decisions based on chemical pumping medium, temperature, pressure and corrosion and other factors. Thread seal on the chemical pump generally have two forms, one is a threaded connection gasket seal, one is added to fill the economy seal thread, Both occasions for sealing small diameter threaded connection. Thread linking electric diaphragm pump connected Gasket seals is gasket, and screw from only provide clamping force. Labyrinth seal in the rational design, processing well, fully assembled, high speed impeller casting process, with labyrinth seals with good results. But in practical applications customized 316l impeller, chemical pump leak was therefore generated a lot, it is not commonly used in the chemical pump seal. Packing is full of compressibility and resilience of packing into the stuffing box gland rely on axial compression force into radial sealing force, and thus play a role in sealing. This sealing method is called packing, such packing called packing. Impeller | Chengyu Pump | 304 impellers provided by Cheng Yu-Pump Manufacturing Co. Hebei. Hebei Cheng Yu-Pump Manufacturing Co.
