What we mean by slurry is basically a liquid containing solid particles. When you want to pump this slurry, there are different requirements than when pumping only dirty water. A waste water pump cannot handle the solid particles of a slurry. This is where slurry pumps come in handy. , Slurry pumps, are heavy duty and robust versions of centrifugal pumps, capable of handling tough and abrasive tasks.

How does a dredge pump work?

- By increasing the size of the worm housing, the speed at which the media moves is reduced. This lower velocity translates into lower wear.

As wear is a function of speed, slurry pumps should be operated at the lowest possible speed; units typically run at 1,200 rpm or less. Often, direct coupling between the pump and a low-speed motor or other drive makes the most sense. On the other hand, many other applications favour gearboxes to meet the required speed and operating point. In services where variable flow rates are required, variable frequency drives are used to provide the necessary continuous speed variation.

Best for: cooking fragile foods such as eggs, fish filets, breaded cutlets, pancakes, and crepes

The details: These pans solve the frustration of food sticking, and they require little oil for cooking. Plus they’re lightweight, easy to clean, and affordable. But they can’t take the high heat of a cast-iron or stainless steel frying pan. “You’re not going to get much of a sear in a nonstick pan,” says Cindy Fisher, who conducted Consumer Reports’ cookware tests.

And they don’t last as long as cast-iron, stainless, or copper frying pans. “Nonstick is going to wear out the fastest,” Nitahara says. “The nonstick coating is fragile, and once you scratch it, it’s hard to flip an egg.”

In our tests of nonstick pans, we cook four eggs in quick succession. An excellent rating means all four eggs easily slid out of the pan. A poor rating indicates that some egg residue was left behind. To test nonstick durability, we rub the pan with steel wool for 2,000 strokes or until the coating has worn through.

    In addition to size differences, Dutch ovens are available in a variety of materials, such as cast iron, aluminum, and ceramic.  Generally speaking, cast iron pots are the main ones. Cast iron Dutch ovens are known for their excellent heat retention and durability, making them ideal for long, slow cooking.  

Frying Pan

You want to match the pan to the job to get the best results in the kitchen. Skillets and saute pans are versatile, and they can handle most types of cooking methods. However, it is best to choose the suitable pans for your recipe. Take time to assess whether a saute pan or skillet is the right choice.

In the United Kingdom, skillets can also refer to larger, deeper, lidded pots or pans with long handles and legs. In the United States,  the term refers to a dish constructed from a shallow skillet-shaped metal or ceramic pan and includes cooked diced veggies and meats.
