Progressive Cavity Pumps and How it Helps Improve Efficiency in Irrigation

November 16, 2018

As rainfall figures plunge around the globe, crop-filled fields grow ever more dependent on irrigation systems. Just to emphasize their important role in world affairs, a desert can be transformed overnight, and all it takes to achieve this astonishing engineering feat is an efficiently engineered network of irrigated land parcels. Then, getting the water to where it needs to be, the network just needs an efficient and reliable pump.

A Productive Irrigation Prime Mover

Utilizing progressive cavity pumps, the initial water supply comes from the furrows and tanks that form the system gateway. There are special aqueducts here, and they don't always perform at their best, especially in arid regions. In a nutshell, the supply pressures in irrigation engineering networks can be tough to regulate. Now, there are intelligently managed options available, but they usually involve tough scheduling programs and other water metering solutions. By turning to progressive cavity pumps, irrigation networks gain an edge. After all, by design and regardless of inlet water pressure, rotary pumps are built to discharge independently processed flows, which are always constant and perfectly metered.

Agriculturally Capable Pumping Mechanisms

Factories and other process-challenging pumping applications can tolerate an occasional breakdown. A clog in the system stops a centrifugal pump, but everything is restored to normal afterwards. Not so with irrigated fields, for thirsty crops can't tolerate a single day of dryness. If fluid furrows dry up, a significant quantity of a community-supporting crop could be gone by harvest time. Again, helical pumps won't issue a single hiccup when a clog comes down the line. Capable of processing solids or thick fluids with equal efficiency, progressive cavity pumps are entirely reliable. That's a feature that can't be stressed enough in farming and community irrigation applications.

Meters Alternate Fluids Sources

Irrigation science is all about getting artificially gathered water to its destination. Even if that destination is a kilometre up an inclined slope, this fluid conveyance family will achieve its mission, and it'll do so with some unmitigated low-velocity ease. Better yet, though, the helical rotor is coated and strengthened so that it can deliver shear-free loads of manure straight to the farthest corners of uneven fields. And, should the terrain need more food, the hardened rotor and elastomeric stator can soon pull in a stream of liquid fertilizers.

Even the outlines of a progressive cavity pump favour irrigation applications. Narrow and cylindrical in shape, they orient vertically and drop down into water wells. Expect to see one or two pumps of this type in irrigation applications. One is used for water pumping purposes, while the other is used to process granular feed and liquid fertilizers.
