Electric Diaphragm Pump PVM — 12V DC (SKU: 050-276)

 

    Heavy-duty 12V DC diaphragm pump engineered for demanding transfer, drainage and bilge duties. The PVM series is a self-priming, volumetric diaphragm design that can run dry without damage and handles liquids containing solids or abrasive particles (sand, mud, sludge, seaweed), making it ideal for marine, RV, caravan, septic and industrial cleanup applications.  

 

Key features

 

   
• 12V DC, robust 0.37 kW (approximately 370 W) motor — reliable continuous duty performance.
   
• Self-priming and immediate priming from dry for fast startup.
   
• Designed to pump liquids with suspended solids; resists clogging and requires no impellers, mechanical seals or foot valves.
   
• 1½" (40 mm) hose inlet and outlet for high-flow transfer and easy hookup.
   
• Standard nitrile (NBR) diaphragm and check valves; Viton options available for enhanced chemical/saltwater resistance.
 

 

Why choose the PVM 12V diaphragm pump?

 

    The PVM 12V is built for longevity and low maintenance — its simple diaphragm action eliminates common failure points found in impeller pumps. Suitable uses include bilge pumping on boats, draining basements, emptying septic or wash-down tanks, transferring diesel or other fluids, and removing slurry or dirty water where solids are present. Its construction and materials make it a good fit for both freshwater and saltwater environments when specified with the correct diaphragm/valve materials.  

 

Installation & operation notes

 

    Follow recommended hose diameter (1½") and avoid inline flow-restricting valves on suction/discharge which can affect volumetric performance. The pump’s ability to run dry and self-prime simplifies installations where foot valves or pre-filling are impractical. For corrosive or fuel service, request Viton diaphragms and valves.
