Polyurethane stator for a progressive cavity pump
A progressive cavity pump including a shell, a stator removably affixed within the shell, a rotor positioned interior of the stator within the shell and a motor interconnected to the rotor so as to rotate the rotor. The stator is formed of polyurethane material. The polyurethane material of the stator has a durometer hardness of 50-98 shore. The polyurethane material of the stator has an operating temperature of between 212° F. and 400° F. The polyurethane material of the stator had a tensile stress of between 100-5100 p.s.i. The stator is positioned between the fluid inlet and outlet of the shell.
