Machine-rocking pumps of balance
Machine-rocking pumps of balance are used for individual drilling of sucker-rod well pumps and they jointly operate as the equipment for oil well exploitation. Manufactured goods are executed in two variants:        - for high foundation mounting;        - for low foundation mounting (with elonglated bearing under the reducer and cross-arm of machine-rocking pumps).     A four-linked transforming mechanizm of drive is implemented according to the asymmetric scheme and its optimum selection is allowed to reduce the overall dimensions and the bulk of machine-rocking pumps, and also onsumed power. High reliability and durability of machine-rocking pumps are guaranteed.     The plant has been carrying out the modernization of manufacturing and can develop the output of new models in agreement with both parties at the earliest possible date.
