Abstract
Disclosed are embodiments of a pumping system with connectable and disconnectable pumping assemblies coupled to suction and discharge manifolds. In an embodiment, the pumping system includes a pulsation dampening assembly including a variable volume chamber fluidly coupled to the discharge manifold. In addition, the pumping system includes a controller coupled to the pumping assemblies. The controller is configured to detect a pressure pulsation based on a measurement from at least one of the pressure sensors, and is configured to adjust the rotational speed of the driver of at least one of the pump assemblies. In addition, the controller is configured to adjust a volume of the variable volume chamber of the pulsation dampening assembly based at least in part on the measurement from the at least one of the pressure sensors.
