downhole-sucker-rod-pumps-sshn

Sucker-rod pumps are designed for oil extraction from deep, superdeep wells on oilfields. All pumps meet requirements of Ukrainians and Russian standards and international standard API Spec 11 AX.

Short description of pumps
Cylinder It is made of a thick-walled precision pipe from St.38Х2МЮА, strengthened by deep nitriding (h = 0,25 … 0,5 mm).
Plunger It is with sludge removable flutes strengthened by hard-alloyed powder ПР10Н70Х17С4Р4, hardness HRC 63-70.
Valve (a pair “saddle-ball”) Steel: a saddle – St. 40Х13, ground in from two sides, hardness HRC 61-64, ball — St. 95Х18Ш, hardness HRC 80
Ceramic-metal: a saddle and a ball from ceramic-metal on the basis of carbide chrome HRC 63-80.
