The distinguishing feature of the cam rotor pump is the high suction, which allows gas-liquid mixed transport, high efficiency and high lift. This is why the petrochemical industry is gradually adopting such pumps.
There are many centrifugal pumps used in the petroleum and petrochemical industry. The difference between cam rotor pumps and centrifugal pumps is that when air enters, it does not affect the normal operation of the pump, and its working principle. When the pump is initially started, the pump discharges air and imports The pipeline is sucked into vacuum, so its self-priming does not need to install a bottom valve or a filling pump, and its suction vacuum is the current strong international level. In addition, the working efficiency of cam rotor pumps is relatively high in all volumetric pumps. Compared with the screw pump, its efficiency is more than 30% higher. This not only saves investment in supporting facilities (transformers, cables, etc.), but in the long run, the energy saving effect is very obvious.
Another feature is that the cam rotor pump is not sensitive to impurities and is a positive displacement positive displacement pump, so it is very suitable for working conditions containing impurities or high viscosity media.
To sum up, the working conditions that require self-priming, gas-liquid mixed transportation, high viscosity media and very high impurities, the cam rotor pump is more suitable, the comprehensive cost-effective (low comprehensive cost), and high efficiency and energy saving are also significant advantages.
Here are some examples of application conditions:
Lift pump: sewage, oily sewage, sludge, other sewage. The cam rotor pump has a strong ability to pass impurities, no need to fill the pump, high suction stroke, and the unit is installed on the ground, which is safe and reliable.
Warehouse sweeping and clearing: strong self-priming ability, mixed gas-liquid conveying, can clean the bilge / bottom bottom medium.
