The Jabsco 42630-2900 Par Max 1 pressure-controlled water pump delivers reliable, self-priming performance for marine and recreational water systems on 12V DC power. It provides 4.2 liters per minute (0.9 gallons per minute) open flow and uses an integrated pressure switch (cuts in at 1.5 bar/22 psi and cuts out at 2.4 bar/35 psi) to maintain steady water delivery to a single outlet. A double-diaphragm design supports self-priming up to 1 meter vertical lift and run-dry operation without damage, while compact dimensions and compatibility with 10 mm (3/8") or 13 mm (1/2") bore hoses simplify installation in tight spaces; this item is stated as no longer available, with Flojet RLFP122202A listed as an alternative.
