What is the open hopper feed progressive cavity pump in block construction?

The open hopper progressive cavity pump in block construction is a kind of direct-coupled progressing cavity pump, its hopper is usually square or rectangular, because it has coupling rod with auger and force-feed chamber, so it can tansport some materials with high viscosity and poor fluidity with continuous, pressure-stable, gentle and low-pulsation.

A progressive cavity pump is a type of positive displacement pump that is designed to handle extremely tough pumping applications and high viscous fluids.

Progressive cavity pumps are ideal for applications where the liquid is shear sensitive again because of lower internal velocity. A good example would be pumping oil and water mixtures to separation devices. The separation device works much better when the oil droplets are larger.

A fluid film is needed to keep the sliding (contacting) surfaces lubricated. These pumps fail when run dry. Progressive cavity pumps are slower moving and don’t produce large amounts of flow.

Open Hopper Pumps are a type Progressive Cavity Pumps. The open hopper pump inlet allows gravity flow of highly viscous media on to the augur-on-coupling rod which pushes the substance to the pumping element.

The progressing cavity pump is commonly used in various industries such as oil and gas, wastewater treatment, food processing, and chemical processing. Its applications include pumping viscous fluids, handling abrasive or corrosive materials, transferring sludge or slurry, and dosing chemicals accurately.
