What are Peristaltic Hose Pumps?
The peristaltic hose pumps are the types of positive displacement pumps that can pump wide variety of fluids. These pumps comprise of inner circular casing inside which the reinforced hose is fitted and inside which the fluid to be pumped is contained. The rotor part of the peristaltic pump has a number of shoes attached to its external circumference.
When the rotor is rotated by the motor, a part of the hose gets compressed and closed and it forces the fluid, which is to be pumped, through the hose. This process of pumping is called as peristalsis and it is similar to those occurring in many biological systems like the ones in gastrointestinal tract.
The peristaltic hose pumps are used in the mining industry for dosing process reagents, polymers and slurry transfer. In the water works peristaltic hose pumps are used for dosing lime, hypochlorite, polymer, and ferric chloride and transferring sludge and filter press feeds. In the chemical industry these pumps are used for the pumping of corrosive acids, bases, and hydrocarbons. In the food and beverage industry peristaltic hose pumps are used for the pumping of breweries, wineries, dairies, sugar refining, bakeries, abattoirs and fish processing. There are many other industries like paint, textiles, ceramic, agriculture and others where thick and non-uniform fluids are to be pumped, and where the peristaltic hose pumps can be used effectively.
