Damage to slurry pumps can range from burst seals to bearings and component housings wearing out where they join, to impellers corroding due to cavitation or severe wear and so on. However, there are solutions to these problems.

Under ideal conditions, a dredge pump can produce fluid acceleration greater than the speed of its fastest moving component.

The basic mechanical seal flushing programme is very simple. It requires that a clear/clean fluid (usually water) is introduced into the space between the actual seal and the impeller side outlet restriction. The flushing fluid is introduced at a pressure higher than the pumping pressure, thus ensuring positive outflow/flushing of the mechanical seal and a clean operating environment.

Redispersible powder, the full name is redispersible powder, the name directly corresponds to its descriptive characteristics. It is a kind of polymer emulsion powder after spray drying treatment, and has the ability to re disperse in aqueous solution to form emulsion .The main components of redispersible powder include the following aspects:

One of the most critical factors in HPMC is its viscosity, which is measured in centipoise (cP). Viscosity grades typically range from low to high, influencing the thickness and texture of solutions in which HPMC is used. Low-viscosity grades, such as HPMC E5, are ideal for applications requiring a thin, flowable consistency, like in sauces and soups. In contrast, high-viscosity grades, such as HPMC E50, provide a more substantial, gel-like texture, making them suitable for products like creams, lotions, and other cosmetic formulations.

Manufacturers in this sector are particularly focused on meeting strict regulatory requirements. They invest heavily in research and development to create HPMC products that are not only effective but also safe for human consumption. The variation in grades ensures that pharmaceutical companies can select HPMC tailored to their specific dosage forms.

The backbone of HEC is based on cellulose, which consists of repeated glucose units linked by beta-1,4-glycosidic bonds. In its natural form, cellulose is crystalline and insoluble in water. However, through the process of etherification, where ethylene oxide is reacted with the hydroxyl groups on the cellulose polymer, HEC is created. This modification results in the introduction of hydroxyethyl groups (-CH2CH2OH) into the cellulose structure. The presence of these hydroxyethyl groups distinguishes HEC from unmodified cellulose, enhancing its solubility in aqueous environments.
