Keramet-Perm LLC is constantly engaged in scientific research and product quality improvement. Currently, development work is focused on the following areas:

The stage is designed for operation in conditions with high salt and solids content, high associated gas content, and for the production of high-viscosity oils. A pump assembled from these stages can operate without flow interruption (with only a slight reduction) even with the impeller's robust channels completely clogged with solids.

Stages with open impellers have good hydrodynamic characteristics, a relatively high head, and efficiency. Furthermore, these stages offer increased head due to their low installation height. The low weight of the impellers and the low installation height of the stages reduce the weight of the rotating pump parts, reducing dynamic imbalance and vibration during operation.

Using these new stages in an ESP significantly reduces the length of the submersible pumping unit and, in some cases, eliminates the need for complex devices such as a gas separator and disperser, which reduce reliability and create operational problems.
Associated gas content of up to 45% is permitted (for comparison, a conventional ESP pump allows up to 25%, and a VNN pump with a vortex ring allows up to 35%).

We currently produce two open stage models: 5-15 and 5-20. The 5-20 stage has been produced since 2011 and has been successfully used as part of ESP units at the following companies:
1. RN-Krasnodarneftegaz (deliveries through Borets SK LLC): the units were used in wells with high propane content, where pumps with conventional closed-type stages failed altogether (the flow cavities immediately clogged and the pump stopped flowing).
2. RN-Yuganskneftegaz (deliveries through Borets SK LLC): repair parts.

Potential applications:

• wear-resistant friction units;
• mechanical seals for pump and compressor equipment;
• plain bearings for submersible centrifugal pumps;
• working parts for chemical pumps;
• sandblasting nozzles;
• spray drying nozzles;
• thread guides for the thread industry;

Potential applications:

• wear-resistant friction components (the third hardest material after diamond and cubic boron nitride);
• sandblasting nozzles, nozzles for spraying pulp and fertilizers (several times more durable than silicon carbide);
• elements of mills and other grinding equipment.
