Automatic operation features wide-angle float switch (W-A1), or Hydromatic's exclusive pressure diaphragm switch (D-A1) or Hydromatic's vertical, mechanical float switch (V-A1). All switches feature a piggyback plug-in arrangement that allows for simple conversion to manual operations.

Cast iron body and an oil-filled motor provide superior cooling characteristics for longer pump life. Motor windings contain automatic thermal overload protection.

Energy efficient .3 HP motor pumps up to 38 GPM at 10' total dynamic head. Discharge is 1-1/2" N.P.T.
