Product Description

12 or 24 Volt – 28LPM – 20 to 40PSI –  Suits 19mm Hose Fittings

(Replaces the discontinued Dual Sensor Max System J20-126 and J20-127)

Self Priming – Includes 2 x Par Max 4 Auto Pumps, Integrated Accumulator Tank & Fittings

High capacity integrated dual pump system for larger vessels where water demand may be high at multiple outlets:.

Popular replacement for the pumps with VSD that were installed on many Maritimo brand boats.

It combines 2 x Par-Max 4 quad diaphragm automatic pressure pumps complete with moulded base, integrated accumulator tank, filters, hoses and all plumbing connections fully factory fitted ready to go in 1 complete unit. The 2 stage pump system operates automatically via a pressure switch when a faucet is opened or closed. Under low demand conditions only the primary pump operates delivering up to 3.8 GPM with low amp draw. Under high demand the secondary pump is activated and the fl ow will increase up to 7.5 GPM. Under maximum demand the total current draw is only 15 amps at 12v or 7.5 amps at 24v. The accumulator tank with bladder smooths out the water fl ow and reduces on/off cycling of the pump by lessening the pressure variation. It also gives better control of hot water temperature for showers.
