Pulsar DLCM Controller

0ºF-104ºF (-18ºC-40ºC)

The DLCM controller for Pulsar pumps is a significant enhancement to the DLC controller. The DLCM provides the same features as the DLC, with the added capability of motor speed control. Variable speed is accomplished through the use of a tachometer feedback loop controlling a standard DC motor. This combination of variable stroke length and stroke speed control further extends the flexibility and capabilities of the Pulsar Pump.
