Advantages
The filtering surface of the PPM-FE offers low hydraulic resistance and high-quality filtration starting from 5 microns. The combined layer-by-layer design of the PPM-FE filtering structure, enhanced with advanced technological materials and coatings (such as basalt fiber, hydrophobic/hydrophilic coatings), addresses specific and complex filtration challenges, including improving filter regeneration and extending service life.
The facing protective wire of the filtering section safeguards the filtering surface from mechanical damage during tripping when used as part of filters for downhole equipment.
The internal drainage wire ensures efficient operation of the filtering surface, maintaining a tight fit to the filter casing.
The flexible-extended filter element provides effective filtration within the specified range.

Equipment purpose:
The filter of the ball reverse valve is designed to protect the ball-seat valve pair from sludge falling from oil-well tubing on it.

- - Reduction of the valve pair wear with a consequent increase in the flow rate of the downhole equipment.nts to recover during servicing operations.
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.
