The PEMSCO Positive Displacement Down-hole Motor was introduced with the latest design and manufacturing technology including state of the art assembles lines with controlled thermal treatment and rubber stators.
Now we can manufacture 16 specifications of 60-286mm in diameter, 3.5MPa, 7MPa and 14MPa pressure difference series, including single lobe and multi-lobe, single bent and double bents motors, adjustable bents motors, which can match different kinds of stabilizers and over 400 varieties of down-hole motors. It can be used in the conditions of 4-1/2” - 26” inches well bore, output torque range 640 -18010 N.M and output speed range 60-500 R/Min. To adapt to the demand of market, recent years we have developed a series of PDM which provide higher torque, more power, high temperature tolerance and long-life. Besides, we developed PDM with small diameter OD. For slim-hole, coiled tubing and workover application, air/foam PDM for air unbalance drilling application and PDM for special drilling fluid applications such as potassium drilling fluid. Many technologies of PDM acquired National Patent Certificate.
