gear pump seal kit

In conclusion, wiper oil seals are vital components in both automotive and industrial applications. They play a critical role in maintaining the efficiency and safety of machinery by preventing fluid leakage and contamination. Regular maintenance and timely replacement of these seals are imperative to ensure the optimal performance of various systems. Understanding their function and importance can help operators minimize downtime and avoid costly repairs, ultimately enhancing the reliability of their equipment.

4. Cost Efficiency While there may be an initial investment in quality seals, the long-term savings through reduced maintenance and operational interruptions are significant.

Cellulose is the most frequent polysaccharide in nature consisting of (some hundreds up to ten thousands) β-glycosidic linked glucose molecules. It is the main constituent of plant cell walls and vegetable fibre. It occurs mostly associated with hemicelluloses and lignin. It is therefore a common component of plant-based feed for all food producing and companion animals. However, these animals are not capable to digest cellulose enzymatically due to the lack of cellulases. The monomer element of cellulose, glucose, will not be released from cellulose. But gastrointestinal microbes can split cellulose, the main degradation products are short-chain fatty acids. In a simplified view, monogastric animals cannot digest cellulose, small amounts are microbially degraded in the large intestine. Minor amounts of cellulose may be absorbed as such by paracellular transport (passing through the intercellular space) or by transcytosis (transcellular transport of macromolecules captured in vesicles). On the other side, animals with large fermentation chambers in the intestine, such as ruminants, horses and rabbits, utilise large amounts of cellulose as energy source. In summary, cellulose is a natural part of feed and plays a physiological role in nutrition of animals (see Section 3.2.1).

Residues of cellulose and breakdown products in edible tissues and products from animals fed HPMC are not expected. Although the (partial) degradation of HPMC would eventually occur in some species (ruminants, hindgut fermenters), breakdown products would still likely be of high molecular weight and poorly or not absorbed; the short-chain fatty acids resulting from microbial breakdown of cellulose in the rumen or hindgut will enter the physiological pools of the animals. The consumer would therefore not be exposed to the additive or derived products when consuming edible tissues and products from animals given diets containing HPMC. Consequently, the FEEDAP Panel concludes that the use of HPMC in animal nutrition is of no concern for consumer safety.
