Operation concept:
The reverse valve is installed on the outlet side of the pump. Oil-well tubing is attached upon the valve.
When the pump is turned on, pressure is rising under the ball and it rises from the seat, allowing fluid to pass through. The fluid flow passes through the holes of the discharge grill and takes effect on the filter, lifting it up. When the pump stops, the ball falls into the seat and prevents the reverse flow into the pump.

- Driven by the spring filter falls on the discharge grill and prevents the deposition of solid particles in the area of the valve pair. As a result, a leak-proof fit of the ball into the seat is provided, it prevents the turbine rotation of the centrifugal pump and protects the seat from abrasive wear by solid particles falling from the oil-well tubing.
Advantages:
- Easily integrated into various types of non-return valve systems
- Repeatedly involving the work of the valve pair
- Can be produced with the required fineness of filtration
- Currently, the operating time of most of the upgraded check valves exceeds 700 days
Function:
The protective element is installed above the check valve grille.
When the pump stops, the sludge settles on the PM protective element, which traps particles of any geometry, so that the sludge does not enter inside the valve and does not violate its tightness.
In the process of pumping and starting the engine after stopping, the liquid containing impurities freely washes the protective element and washes out the deposited sludge from it, completely cleaning the protective element, which rises under the pressure of the medium, which becomes possible due to the unique property of PM - low hydraulic resistance and, as well as specific umbrella shape, which allows you to clear the so-called "dead zone".
And a special oleophobic coating of the element of our own design ensures the free passage of an oil-containing medium and prevents the deposition of heavy oil components - asphaltenes, resins and paraffins - on the surface of the element.
The simplicity of the design allows you to upgrade the existing stock of equipment. PM material can be made with different filtration fineness from 5 to 500 micrometers.

REFILTER Georgia manufactures advanced filtration systems designed to protect Electric Submersible Pumps (ESP) and Progressing Cavity Pumps (PCP) from abrasive solids, fines and shlam produced during well operation. Our filters are engineered using next-generation Wire-Permeable Materials (WPM) – a technology that provides exceptional mechanical strength, high porosity and stable filtration efficiency under extreme downhole conditions. The solutions developed by REFILTER are used to extend pump run life, reduce nonproductive time, and ensure stable inflow even in wells with high sand production or severe corrosive environments. High-Performance Wire-Permeable Technology WPM technology forms the core of our filter elements. The multilayer elastic structure creates an open, three-dimensional porous system capable of precise filtration from 5 to 600 microns, while maintaining low hydraulic resistance. The material preserves its performance under high differential pressures and temperatures up to 800–900°C, and remains resistant to sulfide stress cracking and acidic environments (pH 0–13). Thanks to the elastic structure, WPM-based filters are suitable for deviated and curved wells, where conventional rigid filters often deform or lose efficiency. One of the key advantages of WPM filters is their ability to regenerate. During operation, solids accumulate on the outer surface of the filter, forming a natural pre-filter. After flow interruption or back-flushing cycles, the elastic structure releases accumulated particles and restores up to 90% of initial filtration capacity, significantly reducing service and replacement requirements. Filters for ESP Installations REFILTER Georgia produces filters tailored for high-flow ESP systems operating in challenging well environments. Our filters reduce pump erosion, prevent intake plugging, and withstand solids carryover during well start-ups, post-hydraulic fracturing flowback, or unstable flow regimes. Laboratory tests confirm that WPM filters maintain structural integrity at differential pressures up to 25 MPa, offering superior erosion resistance compared to Johnson-type slotted screens. Due to high porosity and the round-wire structure, our filters ensure 4× higher throughput and up to 7× larger open flow area, improving pump intake efficiency without compromising filtration quality. Filters for PCP Pump Systems PCP installations often face abrasion challenges caused by suspended solids and fines. REFILTER’s PCP filters prevent solids ingestion and reduce stator and rotor wear, significantly increasing pump longevity. The technology is compatible with both vertical and highly deviated PCP wells, maintaining stable filtration even under cyclic load changes. Shlam Protection for Check Valves In addition to filtration modules, REFILTER Georgia manufactures a unique shlam protection device for downhole check valves. During pump shutdowns, solids and corrosion products tend to settle inside the tubing string and accumulate in the valve seat area, causing loss of integrity and hard starts. Our elastic WPM-based protective element isolates the valve pair during shutdown and releases accumulated solids during the next start-up, ensuring reliable valve performance throughout the pump’s life cycle. This solution has demonstrated excellent field results, preventing plugging and improving pump restart efficiency. Benefits of REFILTER Filtration Systems High erosion, corrosion and deformation resistance Stable filtration from 5 μm down to 0.2 μm (in WPM-UR configuration) Self-cleaning capability through elastic regeneration Suitable for high-angle, deviated and horizontal wells Compatible with aggressive media and high temperatures Significant extension of ESP/PCP mean time between failures Optimized for high-solids environments, including post-frac wells Manufacturing Excellence in Georgia Our production facility in Georgia employs modern equipment and strict quality control standards inspired by international oilfield practices. Every filter and protective device is engineered to deliver long-term reliability and performance, even under the most demanding reservoir conditions. REFILTER’s filtration technologies provide operators with a proven, cost-effective method to reduce pump failures, protect artificial lift equipment, and maintain production stability in modern high-complexity wells.
