Peristaltic pump is a hose type of positive displacement medical pumping equipment. It is used for pumping of a variety of fluids. Their operation principle is based on peristaltic pushing of fluids through tubes or elastic hoses. The work of the equipment is similar to that of intestinal wall.
Peristaltic pumps have found their place on the global market in the mid-XX century. Fluids, pumped with the help of such devices, pass through the tubes and hoses due to mechanical pressure.
The operation of such systems has several constraining factors, the main of them being:
These factors exist due to peculiarities of materials, of which the pumping devices are made. As a rule, the acceptable temperature of fluids pumped is 90°C and the pressure limits are 7-16 bars.
If you are looking for reliable and high-quality lab equipment, it is necessary to make up your mind regarding its’ type. Manufacturers offer tube and hose devices. They differ in elastic wet parts and elements. In the former case tubes are used as wet part and hoses are used in the latter. Polymer materials are used to manufacture tubes for peristaltic pumps. Due to this, the pumps have the following characteristics:
When choosing lab equipment, evaluate beforehand the chemical passivity of the tube against the fluids transported. Modern models are manufactured as separate hydraulic devices or as monoblock units along with reducing elements. The second variant is preferable for laboratories, as monoblock models are easier to assemble, more compact and lighter.
