  Lake Petroleum also can offer parts and components of sucker rod pump according to the uses requirements, such as barrels, plungers (note: we can also offer Monel plunger), valve balls, seats and cages, etc. the common combinations of the material and surface treatment for the barrel and plunger manufactured in the company are as follows.

  The barrel of the pump is suspended, so the load on the barrel is small and the deformation of the barrel is small so as to avoid sticking pump because of the elongation and attenuation of the barrel. As compared with the common pumps, the pump is longer in life.
It is mainly composed of barrel assembly, plunger assembly and outer tube assembly.
