Saving Energy With Progressive Cavity Pump

A versatile pump used in a variety of sectors is the progressive cavity pump. It is specifically made to handle very abrasive fluids. Let's examine the features, advantages, and operation of a progressive cavity pump in more detail in this guide. One kind of positive displacement pump is the progressive cavity pump. It is incredibly flexible and versatile and works best for the most difficult pumping tasks, handling extremely viscous liquids. It can handle a variety of tasks, including pumping viscous, shear-sensitive, and abrasive materials.

Progressive cavity pumps are sometimes referred to as cavity pumps, progg cavity pumps, and PC pumps. The last 30 years, and the last 10 years, have seen new improvements that have made these pumps simpler to maintain and less likely to trade efficiency for durability. As a result, PC pumps now have lower initial capital, ongoing maintenance, and operating costs. Following are recommendations for choosing a PC pump correctly for a particular application need, notably about lowering operational costs by consuming less energy.

Minimum number of energy transformations

Avoid using air as a source of motive power. The process of turning electricity into rotation with an electric air compressor and then back into rotation with an air-powered motor is inefficient. Air lines leak considerably more frequently than insulated wires, and compressed air also needs to be cleaned, dried, and de-oiled, all of which can drain or add power. In general, air-powered pumps perform at about 15 to 20% efficiency, whereas electrically operated pumps run at 50 to 60 percent overall efficiency (wire to water). The starting torque of air motors must also be considered because it is typically higher than the operating torque. A fair guideline is to consume 4 standard cubic feet of compressed air every minute.

Similarly, problems arise with internal combustion engines. To convert reciprocating momentum to rotating motion, they inefficiently burn fuel. Because internal combustion engines have no starting torque, a clutch is required. The same is true with hydraulic motors; they undergo too many conversions and have the same amount of starting torque as running.

Accurate Geometry

The initial or "standard" progressive cavity shape created by Dr. René Moineau in 1936 features a larger diameter, more eccentric rotors, and a short stator pitch length. Longer geometry stators and rotors began to become popular in the 1960s. It employed reduced rotor diameters and eccentricity along with longer stator pitch lengths. Lowering the beginning torque and increasing general efficiency lowers thrust loads and the rate of attrition in abrasive applications.

In conclusion, there are several ways to choose, buy, and install a PC pump that will reduce running costs and initial capital costs. Completely review the application conditions, maximise initial selections using the methods above, and collaborate with reputable pump providers to determine the optimum option for the facility's requirements.
