March 0115-0007-0400 1U-MD 115V Submersible Magnetic Drive Pump 0115-0007-0400

The March 0115-0007-0400 1U-MD Magnetic Drive Pump is a compact Series 1 submersible-only centrifugal pump designed with a screened suction inlet for compatible chemical transfer, refrigeration, photographic-processing, circulation and water-handling applications. This exact SKU identifies the 115V single-phase complete standard 1U-MD pump.

The 1U-MD uses sealless magnetic-drive technology and a submerged motor configuration. Its inlet screen helps prevent larger debris from entering the pump while allowing liquid to feed directly into the wet end.
