Cam pumps got their name through protrusions on the rotors - “cams”. This product is best suited for thick and viscous liquids. It efficiently pumps products without destroying its structure. Therefore, the devices are even more popular in the food, cosmetic, and pharmaceutical industries. The cam pump safely pumps yoghurt from some fruits, wine, cosmetics and confectionery creams, etc.
How a cam pump works
The principle of operation is not as simple as, for example, peristaltic pumps, but also quite intelligent . There are shafts installed on the bearings of the housing, to which 2 rotors are attached, which wrap around the opposite direction. It rotates synchronously without contact with each other, possibly due to special gear wheels that drive the drive shaft. If the rotor cams come out of the cleavage, the volume of the chamber between them increases, which causes rarefaction and tide in the middle of the winding pipeline. While turning, the rotary cams are drawn close to the outlet pipe.
Advantages and disadvantages
Buy a cam pumpVarto for the following reasons:
- You can pump speech with a sensitive structure. If the fluidity of the flow during the hour of operation of the device is low, the structure of the working unit becomes unbreakable.
- Ensures an even flow of the unit. Due to this particularity, it is possible not to use pulsation dampers, which saves money and saves money on the robot.
- It has a reliable and valuable design. A properly selected cam pump that undergoes regular maintenance will last for decades. Of course, there are significant output characteristics here. If you don’t save money and buy well-known brands, such as Tapflo, that’s half the success.
- Easy technical maintenance and easy repairs. I will add one part as soon as it wears out - the end reinforcement. It will take no more than a year to replace it by a qualified technician.
- Low noise level and hygienic design. These are especially important indicators for the food industry, sanitation is important and there are a lot of adjustments at the same time.
The only thing that is missing from this technology is the high price of production.
How to choose a cam pump
Tobuy cam pumps for the food industry, consider the following characteristics:
- productivity: folds 0.001-1700 m³/year;
- power of the electric motor: depending on the model, it can be 0.1-3000 kW;
- production materials: stainless steel is most suitable for products;
- li>
- density of the vents to be pumped: 300-3500 kg/m³;
- temperature during the hour of operation: up to 140°C;
- temperature of the working vent: -109°C — +450°C;
- visibility of the housing protection;
- maximum concentration of solid particles in the radius: 0.01-150 mm;
- rozhunkovy vise of the sealed housing: 4-64 bar.
Remember this important rule: pumps of this type cannot be used as self-priming pumps. These types of equipment are extremely vulnerable, as a result of which the equipment breaks and may not be repairable.
