high quality centrifugal slurry pump spares

3. Both pumps and motors are designed separately.

Centrifugal slurry pumps capable of providing high capacity with a limited head are mainly used for pumping slurry through pipes with a concentration of less than 70% by weight of solids. Centrifugal slurry pumps can be vertical, horizontal or submersible.

As described below, there are several >types of pumps that are suitable for pumping slurries. However, before considering which technology to use, we must address several key issues.

One of the most frequently asked questions from our team of pump experts is: How do I pump slurry? With this in mind, our team of experts have provided a useful guide to pumping slurry.

Slurry Pump

If a centrifugal pump, is the design and material used to construct the impeller suitable for pumping slurries?

CSPI says it might reconsider its rating if specifications for food-grade titanium dioxide in the U.S. are updated to ensure nanoparticles are minimized, and new studies are conducted to assess its capacity to cause cancer or other health problems. 

Risk managers at the European Commission and in EU Member States have been informed of EFSA’s conclusions and will consider appropriate action to take to ensure consumers’ protection.

There’s also concern that exposure to the mineral over time, even in small amounts, can build up in the body, particularly in the kidneys, spleen and liver. Although most of the mineral is excreted in feces, there is evidence that a small percentage may remain in bodily organs.

Titanium dioxide mainly comes from the earth’s crust, where it’s actually the ninth most common element. When processed, it becomes a fine powder with a vibrant white pigment.

The calcined product obtained by the ordinary zinc-barium white preparation method is beaten into a slurry, which is then surface-treated with sodium silicate, aluminum sulfate or sodium aluminate and surfactant, and then filtered, washed, dried and pulverized. Can.

Safety

The EU expert panel did not identify an immediate health concern linked to TiO₂ when used as a food additive. However, due mainly to uncertainties concerning the safety of TiO₂ nanoparticles, the panel concluded that TiO₂ as a food additive (E171) could no longer be considered safe.

No. The titanium dioxide we use in our toothpastes has been proven safe by health experts around the world. It is used in our toothpastes as a white colourant, in a non-nano form as defined by European regulations. It is an approved colourant in cosmetics, and we comply with all the regulations applicable to it.

The element titanium and the compound TiO₂ are found around the world, linked to other elements such as iron, in several kinds of rock and mineral sands (including a component of some beach sands). Titanium most commonly occurs as the mineral ilmenite (a titanium-iron oxide mineral) and sometimes as the mineral rutile, a form of TiO₂. These inert molecular compounds must be separated through a chemical process to create pure TiO2.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Market Dynamics

One of the most widely used food pigments is titanium dioxide, an odorless powder that enhances the white color or opacity of foods and over-the-counter products, including coffee creamers, candies, sunscreen, and toothpaste (1Trusted Source, 2Trusted Source).
