Description
Circulate seawater for small marine air-conditioning systems under 6,000 BTU with the CTM Marine PM250L-115 Submersible A/C Pump. This fully submersible seal-less magnetic-drive centrifugal pump is specified as a direct replacement for compatible 115V March PML250 and LC-2M-MD units. It provides a maximum rated flow of 300 GPH (5.0 GPM / 18.9 LPM), maximum head of 15 ft (4.6 m), and maximum pressure of 6.5 PSI.
CTM Marine model PM250L-115 uses a glass-filled reinforced-polypropylene casing, precision ceramic shaft, and seal-less magnetic-drive construction. Its heavy-duty epoxy-encapsulated hermetically sealed motor operates on 115V AC, 50/60 Hz single-phase power. The pump has a 3/4-inch FPT inlet, 1/2-inch MPT outlet, and listed ISO 8846 and USCG marine ignition protection.

Compatibility and Installation
The CTM Marine PM250L-115 is specified for compatible 115V marine A/C seawater-circulation systems and replacement applications involving compatible March PML250 or LC-2M-MD pumps. Confirm the existing pump model, voltage, frequency, electrical connection, mounting dimensions, inlet and outlet threads, required flow, and system head before ordering. The direct-replacement statement should be verified against the existing installation and vessel-system requirements.
The 300 GPH rating is a maximum pump rating. Actual output depends on total dynamic head, intake restrictions, strainer condition, plumbing diameter and length, fittings, discharge restrictions, and electrical supply. Install with suitable marine seawater intake, seacock, strainer, plumbing, circuit protection, and bonding components according to manufacturer documentation and vessel requirements.
