Filter intake module FPPR
Function
The suspended filter FPPR, equipped with filtration elements made from a permeable matrix of pressed metal wire (PM), is designed for use in bottom-hole pumps and sucker-rod screw pumps with nominal outputs of 150 to 1000 m³/day. It prevents the penetration of solids such as sand, proppant, and other particles sized 100 to 500 µm into the pumping units.

Advantages
- Enhanced reliability and effective operation of ESP units.
- Increased run life of bottom-hole pumps and sucker-rod screw pumps.
- Modular structure of the filtration system based on PM material.
- Crevice effect of compressed wire mesh ensures filtration elements remain clear of solids.
- 1.5 to 2 times reduction in total filter length due to the high porosity of PM material and low hydraulic resistance compared to slotted and screen filtration systems.
- Long-term operation of bottom-hole pumps and sucker-rod screw pumps without a decrease in output.
- Adjustable cutoff rating through controlled compression of filtration elements.
- Insensitivity to shock loads and hole curvature due to the elastic properties of PM material.
- High corrosion and erosion resistance of filtration elements made from PM material.
- Ability of filtration elements to recover during servicing operations.
Design Features
- Bypass valves are incorporated into the filter to prevent a decrease in the flow rate of bottom-hole pumps and sucker-rod screw pumps due to filtration element blinding.
- The ends of the filtration elements are made of stainless steel, which protects the edges and provides rigidity.
- The symmetrical design of the filter simplifies mounting and allows the entire length of the inner supporting tube (housing) to be used as a slurry trap.
- Mounting dimensions follow the thread standard of Ø73 according to Russian Standard GOST 633-80.
