Zusammenfassung:	oil and gas industry. SUBSTANCE: proposed pump includes cylinder housing plunger with pressure valve. Extending nipples with end couplings, intake valve and plunger rest are mounted on ends of cylinder. Intake valve is placed aside, out of zone of action of plunger. Lower butt part o extending nipple is fitted with collector of refuse with end cap. Upper part of cylinder has hole communicating with pipe clearance located at some distance from plunger rest that is longer than plunger length. Pump has filter fitted with bottom and cover having proper holes to accommodate lower sealing nipple. Filtering member is fabricated in the form of separable tetrahedron with filtering grid. Groove to take filtering member is located in bottom. Lid of filter has hole for holder of seat of intake valve. EFFECT: simplified maintenance and enhanced productivity of given well sucker-rod pump. 4 dwg
