Acid resistant pump manufacturerprinciple

1. The area of contact between the machine seal and the liquid increases by 3-5 times.

2. The cooling part of the machine seal extends into the center of the pump body, rather than in the corner of the remote pump body.

3. Localized sharp corners disrupt the formation of bubbles.

Acid resistant pump manufacturerOverview

The components of the Yili brand S series acid resistant pump are made of reinforced polypropylene and polyvinylidene fluoride through one-time injection molding. Due to its anti-corrosion performance, simple structure, and easy maintenance, it has been widely used in industries with corrosive environments such as chemical, pharmaceutical, and agricultural pharmaceuticals. Its high efficiency and low price make it an ideal product to replace stainless steel pumps, PTFE pumps, and other non-metallic pumps.

Its vulnerable parts are mainly machine seals, and in addition to normal wear and tear, local overheating and accidental damage can also occur frequently. Our company has organized research forces to tackle customer feedback. In 2012, our company developed a new type of mechanical seal. After actual use by customers, its service life is much longer than that of ordinary WB2 mechanical seals. Protecting customer investments. We insist on making the equipment with the lowest usage cost.

Enhanced non-polar polypropylene, non-toxic, resistant to general acids, bases, and salts, with a working temperature range of -12 ℃ -80 ℃

Polyvinylidene fluoride has good airtightness, no toxicity, non polarity, good oxidation resistance, good mechanical properties, and resistance to strong oxidants, halogens, and aromatic solvents. Its working temperature ranges from -40 ℃ to 135 ℃

structural composition

Main material: Reinforced polypropylene or polyvinylidene fluoride

Mechanical seal: Mechanical seal, double-sided silicon carbide. If used under alkaline conditions, please let us know and we will select a pressureless seal (structure) for you

Motor: Ordinary motor or explosion-proof motor.

feature

1. The smaller the pulsation of the impeller, the higher the performance of the pump and the longer its service life. We have cancelled the design of the pump shaft sleeve and directly connected the impeller to the motor, reducing the impeller's jumping by twice. It also avoids the difficulty of repair and assembly caused by rust on the shaft sleeve and motor shaft when the pump is used in a corrosive environment. Missing a component makes maintenance more convenient.

2. Except for S32 pump, all other models of centrifugal pumps currently use my driver seal, which has a service life of 1 to 3 times that of ordinary seals; And it is unlikely that the centrifugal pump will experience sudden temperature rise and damage to the equipment during normal use.

3. The S32 pump adopts a standard pump structure design, which is different from simplified products on the market.

4. The S80 pump adopts a standard shaft with threaded motor (the pump shaft sleeve is an optional part, making it convenient for customers to choose a standard motor); The pump body adopts a plum blossom edge design, which moves the embedded parts outward to increase the sealing surface and minimize leakage, corrosion of the embedded parts, and damage to the pump body caused by aging of the sealing gasket, resulting in losses to the user.

5. S100 pump, our company redesigned the connection frame structure in 2013, using a short shaft with threaded motor, eliminating the pump shaft sleeve design, and integrating RPP injection molding into the connection frame, reducing the length by one-third and doubling the thickness compared to the original. The impeller jumping is reduced by half.

6. To ensure product quality, we purchased a 7880 5000g injection molding machine worth 1 million yuan, and all injection molded parts were processed by ourselves. Increase compactness, reduce foaming, and improve the quality of injection molded parts. (Very few pump manufacturers purchase this type of extra large injection molding machine themselves)

Machine seal, unchanged price, longer lifespan

Friend, if you have ever used a polypropylene centrifugal pump, you may have encountered a situation where my equipment is clearly in normal use and the water temperature is not too high. Suddenly, the machine seal burns out, the impeller burns out, and the pump body or cover also melts. In a short while, a polypropylene centrifugal pump is finished, costing one thousand or even several thousand yuan.

In excluding the situation of dry grinding of the machine seal, a large part of the reason may be that the liquid in the pump body vaporizes at low temperature under certain conditions (or the gas content in the pumped liquid is high), blocking the cooling surface of the machine seal, causing local dry grinding of the machine seal under normal use. In just a few seconds, the machine seal will quickly heat up to 300-400 degrees or even higher at a high speed of 2900 revolutions per minute.

If you have encountered such a problem during use, * you are using a Yili brand polypropylene centrifugal pump. Our current S series acid resistant pumps S40, S50, S80, and S100 series all use our self-developed machine seals. After several customer trials, the cooling effect is better and the service life is longer, which can greatly avoid situations where the machine seal cooling is not in place and the equipment is damaged.
