24V Diaphragm pump – 4.5 L/min 2.4 bar – Compact Water Pump

Description

The SEAFLO diaphragm pump 24V (model SFDP2-012-035-21) from the 21 series is a compact automatic water pump for small pressurized water systems and fluid applications. Thanks to its space-saving design, this pump is ideal for installations where limited space is available, while still delivering reliable performance.

With a capacity of 4.5 liters per minute and a maximum pressure of 2.4 bar, this pump is suitable for fluid transfer, spray systems, circulation, and small onboard water systems. The built-in pressure switch ensures that the pump starts automatically as soon as a faucet is opened and stops when it is closed.

The pump is self-priming up to 1.2 meters, can run dry without damage, and operates quietly thanks to the diaphragm design. The durable internal materials, such as EPDM valves and a Santoprene diaphragm, ensure reliability and a long lifespan.
