MPH Plastic magnetic pump MPH plastic magnetic pump is in accordance with JB/T 7742-1995 standard for small magnetic transmission centrifugal pump and flow components adopt PPS (PPS) which is not subject to most acid, alkali, salt erosion (except oxidizing acid such as sulfuric acid, nitric acid and aqua regia) and its performance is close to the chemical performance of ptfe, in most organic solvents under 100 ℃, ability of gasoline and methanol mixture in particular. It is the ideal pump in the acid and alkali industries conveying. The shaft and the impeller of MPH plastic magnetic pump are respectively assembled with magnetic materials and attract each other, without the need to match with the traditional mechanical bearings, so it is completely sealed. The rotating torque of the motor is driven by the attraction of the active magnetism and the driven magnetism to drive the blades to work. The biggest disadvantage of the magnetic drive pump is that it is absolutely forbidden to run in the case of lack of liquid, otherwise the whole machine will be destroyed to add unnecessary trouble and annoyance to the user. MPH plastic magnetic pump can have dry running. It adopts a special formulation of ceramic bearings specially designed, with strong abrasion resistance and corrosion resistance, so that its advanced and safe performance can be reliably guaranteed. Magnetic drive circulating pump adopts no shaft seal design, completely avoid the traditional mechanical shaft seal pump existence of liquid leakage caused by corrosion after pollution defects.

Centrifugal pump automatic water supply equipment Working principle: Tap water enters the tank, and the air in the tank is discharged from the vacuum eliminator. After the water is full, the vacuum eliminator closes automatically. When the tap water can meet the water pressure and water demand, the automatic water supply equipment directly supplies water to the water pipe network through the bypass check valve. When the water pipe network pressure is not satisfied with the water demand, the system through the pressure sensor (or pressure controller, electric contact pressure meter) to give a pump starting signal for pump operation. When pump supplies water, water capacity of water pipeline network is greater than the pump flow rate, system can have normal water supply. If water capacity of the tap water pipe network is less than the pump flow rate, the water from water tank as a counter can still have normal water supply. At the moment, the air from the vacuum eliminator enters the tank to eliminate the negative pressure of tap water pipe network for system to recover to normal status. Main components Centrifugal pump, tank, pipeline, pressure sensor, gauge, check valve, gate valve, ball valve etc. Application: Water supply: filtration and conveying in waterworks, water supply in different zones, supercharging in supervisors, supercharging in high-rise buildings. Industrial pressurization: flow water system, cleaning system, high pressure flushing system, firefighting system. Industrial liquid transport: cooling and air conditioning systems, boiler feed water and condensing systems, machine tool kit, acid and alkaline medium transport. Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator and swimming pool water treatment system.

Cassette oil seals are specialized sealing solutions developed for use in machinery that operates in environments where dust, dirt, water, and other contaminants pose a significant risk. Unlike standard rotary shaft seals, cassette seals integrate multiple sealing lips, a dust barrier, and sometimes a pre-lubricated internal cavity. This structure enhances sealing reliability and extends service life under harsh conditions. This article explores which types of machinery require cassette oil seals, explains why they are selected, and provides practical insights for engineers and maintenance professionals. Machinery That Commonly Uses Cassette Oil Seals 1. Agricultural Equipment Machines such as tractors, combine harvesters, seeders, and sprayers work in open fields where exposure to mud, water, and crop debris is constant. Cassette oil seals are commonly installed in wheel hubs, axles, and gearboxes to protect rotating parts and ensure smooth operation over long working hours. 2. Construction Machinery Excavators, backhoes, loaders, and bulldozers are exposed to gravel, soil, and vibrations during operation. Cassette seals help prevent grit and moisture from damaging internal components, especially in swing motors, wheel hubs, and hydraulic systems. 3. Mining and Quarry Equipment Equipment like drilling rigs, crushers, and haul trucks must withstand heavy- duty usage in abrasive environments. Cassette oil seals in these machines reduce the risk of bearing failure and fluid leakage in gearboxes and drive systems. 4. Heavy-Duty Trucks and Trailers Cassette seals are often used in truck axle systems, wheel ends, and braking assemblies, where they resist the effects of road debris, water, and temperature fluctuations, contributing to extended maintenance intervals. 5. Forestry and Logging Machinery Machines used in logging operations face exposure to wood chips, sap, and rough terrain. Cassette seals help protect gear mechanisms and wheel bearings from contamination, especially in harvesters and skidders. 6. Industrial Machinery In some cases, cement mixers, crushers, and conveyors used in dusty plants also benefit from cassette seals to maintain cleaner lubrication systems and prevent premature wear. Frequently Asked Questions Q1: Why are cassette seals preferred over standard oil seals in heavy equipment? A: Cassette seals offer multi-lip protection and are pre-assembled, reducing installation errors. They also resist contamination better and last longer in rugged environments. Q2: Are cassette seals only used in mobile equipment? A: While they are most common in mobile and off-road machines, cassette seals can also be applied in fixed industrial machinery exposed to high levels of dust or moisture. Q3: Can a standard oil seal be replaced with a cassette seal? A: In some cases, yes—but shaft compatibility, space constraints, and seal dimensions must be carefully evaluated. A cassette seal may offer better performance if properly fitted. Q4: What maintenance benefits do cassette seals offer? A: Their robust design helps reduce unplanned downtime and extends the interval between seal replacements, especially in equipment where frequent maintenance is difficult. Cassette oil seals are widely used in machinery that operates under tough and unpredictable conditions. From agriculture and construction to mining and transportation, these seals provide reliable protection against contaminants and wear. Understanding which machines benefit from cassette seals allows for more effective sealing solutions, helping to ensure long-term equipment reliability and reduced maintenance needs.
