12V Diaphragm pump 18.9 L/min 3.8 bar – Water pump 42 Series

Description

The SEAFLO diaphragm pump 12V (model SFDP1-050-055-42) from the 42 series is a powerful and compact water pump for onboard water systems and pressure installations. This pump combines high output with stable pressure and is designed for applications where both performance and limited installation space are important.

With a capacity of 18.9 liters per minute and a maximum pressure of 3.8 bar, this pump provides enough power for multiple outlets at once. Thanks to the built-in pressure switch, the system operates fully automatically: the pump starts when a faucet is opened and stops when it is closed.

The pump is self-priming up to 1.8 meters, can run dry without damage, and is equipped with internal bypass technology that reduces switching cycles and extends lifespan. The rubber mounting foot dampens vibrations and ensures quiet operation onboard.
