Polypropylene Pneumatic Diaphragm Pump P1 – Reliable Marine Ship Supply

This polypropylene pneumatic diaphragm pump (Model P1) is designed for demanding marine and industrial applications where safe, reliable fluid transfer is critical. With a maximum flow rate of 20 L/min and discharge pressure up to 6.9 bar, it handles a wide range of liquids including corrosive chemicals, solvents, and viscous fluids up to 10,000 cP. The pump’s air-operated design eliminates electrical hazards, making it ideal for explosive environments.

Constructed from engineering plastic and PTFE (Teflon) wetted parts, this pump offers excellent chemical resistance and durability. Its self-priming capability with a 5-meter suction lift and ability to run dry without damage ensure trouble-free operation even in challenging conditions. The simple design and minimal moving parts reduce maintenance and extend service life – essential for onboard ship supplies.

Frequently Asked Questions

Can this pump run dry?

Yes, the P1 diaphragm pump can run dry indefinitely without damage, making it safe for applications where fluid supply may be interrupted.

What types of fluids can it handle?

Thanks to its polypropylene and PTFE construction, it is compatible with most corrosive chemicals, solvents, seawater, fuels, and viscous fluids up to 10,000 cP. Always verify chemical compatibility with your specific fluid.

Is it safe for flammable environments?

Absolutely. The pump is fully pneumatic with no electrical components, so it poses no spark risk and is safe for use in explosive atmospheres like fuel storage areas or chemical tanks.

What maintenance is required?

Minimal maintenance is required. Periodically check the air filter, clean the muffler, and inspect diaphragms and ball valves for wear. The simple design allows easy replacement of worn parts.
