The Seaflo 42 Series is the go-to 12V water pump for campervan conversions. It delivers 11.3L/min at 55PSI, self-primes up to 1.8m, runs dry without damage, and stays quiet thanks to its rubber-mounted base — a proven, reliable pump used in thousands of van builds worldwide.

Benefits:

  • 11.3L/min flow rate — enough pressure for taps, showers, and sinks simultaneously
  • Whisper-quiet operation — rubber base absorbs vibration into the cabinet
  • Self-priming up to 1.8m — works even with tank mounted below the pump
  • Run-dry safe — no damage if the tank runs empty
  • Internal bypass reduces cycling — less wear, longer pump life
  • 2-year warranty, RoHS, SGS and ISO certified

Features:

The Seaflo 42 Series uses a four-chamber diaphragm design with an internal bypass valve that smooths water flow and reduces the number of on/off cycles — so your pump lasts longer and your taps feel more like a house system. It handles water up to 60°C, making it suitable for hot water circuits. The fully rubber-mounted base absorbs motor vibration before it reaches your cabinetry, keeping the van quiet even at low pressure. Port size is 1/2" FNPT, and the compact body fits easily into tight under-bench spaces. Used by Vanlifer on many of our own builds.

Pair it with the Seaflo 0.75L Accumulator Tank for even smoother pressure and longer pump life.

People are asking

Is the Seaflo 42 pump enough for a shower in a campervan?

Yes. At 11.3L/min and 55PSI, the Seaflo 42 Series provides adequate flow and pressure for a shower, sink, and tap running simultaneously in most campervan builds. For best results, pair it with an accumulator tank to smooth pressure and reduce pump cycling during showering.

What size hose fittings does the Seaflo 42 pump use?

The Seaflo 42 Series uses 1/2" FNPT inlet and outlet ports. This is a standard thread size for campervan and RV water systems in New Zealand, compatible with most 12mm and 15mm hose fittings using a simple adaptor.

Can the Seaflo 42 pump run dry if my tank empties?

Yes — the Seaflo 42 Series is run-dry safe. It will not be damaged if it runs without water, which is a common occurrence in van builds when the fresh water tank empties unexpectedly. This is one of the key reasons it is popular for campervan installations.
