DC motor diaphragm pump

A compact 12 V / 24 V DC-operated diaphragm pump engineered for reliable liquid handling in industrial, mobile and domestic systems. The pump combines a corrosion‑resistant FRPP housing with replaceable EPDM or NBR diaphragms to handle a wide range of aqueous media and mild chemicals while keeping noise and maintenance low.

Key features

• Voltage: 12 V / 24 V DC — compatible with vehicle, battery and solar power systems
• Pump body material: FRPP (corrosion resistant)
• Diaphragm options: EPDM or NBR (selectable by application)
• Self-priming capability up to 5 m
• Maximum medium temperature: 60°C
• Allows dry running without immediate damage
• Built-in pressure switch for automatic motor protection
• Built-in overflow/relief valve to maintain stable pressure and prevent overpressure
• Low noise operation and easy disassembly for service
• Uses low safe voltage for improved operator safety

Typical applications

• Reverse osmosis (RO) water purification systems
• Filter and separator feed pumps
• Spray equipment and car wash systems
• Chemical metering and dosing
• Hygiene and pollution-control equipment
• Shipboard water desalination and onboard pressurization
• Household tap water pressurization and general industrial fluid transfer

Why choose this pump

Its combination of a chemically resistant FRPP body, flexible diaphragm materials, and integrated protective controls makes the unit well suited to small-to-medium flow, intermittent or mobile installations where reliability, safety and low maintenance are priorities. The pump is particularly useful where self-priming, dry‑run tolerance and low-voltage operation are required.
