These motors are designed for applications requiring high slip torque and high starting torque. Used in oil well beam pumping units and similar applications. Three-phase oil well pump motors are also used in beam pumps, sucker rod pumps, and other applications. These motors provide the high slip torque and high starting torque required by oil well pumpers. Suitable for beam pumps, sucker rod pumps or many applications requiring high starting torque or high sliding torque. Custom-designed motor / pump units are available in multiple configurations for main hydraulic or emergency hydraulic functions. Depending on the application, these units can be DC or AC motors supplied with GC or W series pumps. Single and multi-section pump configurations are available. Depending on the application requirements, many holistic valve options are available to meet the specific requirements of many mobile device applications. From material handling and aerial lifts to heavy-duty applications in construction equipment, concentric experience and proven pump / motor design knowledge can provide motor and hydraulic system performance. The electric oil pump is an oil pump driven by an electric motor, and is used to maintain the pressure of the oil and lubricate the automatic transmission / non-transmission during the engine stop such as stopping the start of the vehicle. Most engines use a wet sump refueling system, which means that the bottom of the rotating parts of the engine passes through the sump and pushes the lubricant up to the cylinder as it rotates. The oil pump is required to push the oil to the top of the motor. There are many pump designs, but each revolves around the concept of a set of gears or rotors, pressurizing the oil by forcing the oil against the housing where the gear or rotor rotates.
