Gianneschi PM40 12V 1” Barbs Diaphragm Pump 40LPM High Flow DC Pump
The Gianneschi PM40 12V diaphragm pump is a high-performance DC-driven fluid transfer solution designed for reliable operation across industrial, utility, RV, and marine-adjacent applications. Built with a robust diaphragm mechanism and 1-inch barb connections, it supports efficient handling of water and compatible fluids at a consistent flow rate of up to 40 liters per minute.
This pump is engineered for self-priming capability, making it suitable for systems where suction lift and intermittent dry-running conditions may occur. Its 12V DC operation allows integration into mobile, off-grid, and automotive power systems, offering flexibility across multiple use cases beyond marine environments.
With its compact form factor and strong flow output, the PM40 is commonly used in water transfer, cleaning systems, agricultural setups, and general-purpose liquid handling where dependable medium-to-high flow performance is required.
