Material: High-quality stainless steel 304 or 316 is usually used as the material for the pump casing, which has good corrosion resistance and is suitable for a variety of chemical media and harsh environments. The gears are generally made of PPS plastic gears or fluoroplastics filled with corrosion-resistant materials such as polytetrafluoroethylene, which not only ensures the corrosion resistance of the gears but also reduces the operating noise.
Sealing: It adopts a leak-free sealing structure design, such as magnetic coupling drive, which can ensure the safe transportation of fluids, effectively prevent liquid leakage, and avoid environmental pollution and safety threats to operators.
The gear metering pump operates through a pair of meshing gears. One is the driving gear, and the other is the driven gear. The driven gear is driven by the driving gear to rotate in mesh. There is a relatively small clearance between the gears and the pump casing. When the gears rotate, in the suction chamber where the gear teeth gradually disengage, the enclosed volume between the teeth increases, forming a local vacuum. Under the action of the pressure difference, the liquid is sucked into the suction chamber. As the gears rotate, the liquid is pushed forward by the gears in two paths between the gears and the casing and sent to the discharge chamber. In the discharge chamber, the two gears gradually mesh, the volume decreases, and the liquid between the gears is squeezed to the discharge port.
High-precision Metering: With a high-precision gear system, it can ensure the precise metering of liquids. The error range is usually around ±1%, which can meet the occasions with high requirements for liquid metering accuracy.
Low-noise Operation: The structural design is reasonable, and the noise generated during operation is relatively low. Generally, it will not cause obvious noise pollution to the working environment, and it is suitable for places with strict requirements for noise.
Stable Flow: The flow is stable during the working process without pulsation, which can ensure the continuity and stability of liquid transportation. It is especially important for some technological processes with high requirements for flow stability.
Strong Self-priming Ability: Some stainless steel metering gear pumps have good self-priming ability. When starting, there is no need for additional priming devices, and they can automatically suck in liquid and start normal operation, which is convenient and fast.
Pharmaceutical Industry: It is used for transporting and metering various drugs, liquid medicines, pharmaceutical intermediates, etc., ensuring the accurate batching and quantitative transportation in the drug production process and meeting the strict quality requirements of drug production.
Food Industry: It can transport various food liquids such as beverages, fruit juices, milk, and edible oil. Due to its safe and hygienic materials, it will not cause pollution to food, ensuring the quality and safety of food.
Chemical Industry: It is widely used for the transportation and metering of liquids such as acid-base solutions, solvents, and chemical additives. It can adapt to various corrosive chemical media and ensure the safety and stability of the chemical production process.
Water Treatment Industry: In the water treatment process, it can be used for the transportation and metering of liquids such as raw water, sewage, and purifying agents, accurately controlling the dosage of water treatment chemicals and improving the water treatment effect.
Laboratory: In various laboratories, it is used for accurately metering and transporting various experimental liquids, such as chemical reagents and biological culture media, providing a guarantee for the accuracy of experiments.
Daily Cleaning: Regularly clean the dirt and dust on the outside of the pump body to keep the appearance of the pump clean and prevent dirt from entering the pump and affecting its normal operation.
Check Seals: Regularly check the wear of seals. If the seals are found to be aged or damaged, they should be replaced in time to ensure the sealing performance of the pump.
Lubrication Maintenance: According to the pump's operation manual, regularly lubricate parts such as the bearings and gears of the pump to ensure its smooth operation and extend its service life.
Periodic Calibration: In order to ensure the metering accuracy, the pump should be calibrated regularly. Calibration can be carried out using equipment such as standard flow meters. If there are deviations, they should be adjusted in time.
