Product Description
JABSCO DUAL-MAX 7.5 - 28litres/minute 24volt - 31670-0094
High capacity integrated dual pump system for larger vessels where water demand may be high at multiple outlets. It combines 2 x Par-Max 4 quad diaphragm automatic pressure pumps complete with moulded base, integrated accumulator tank, fi lters, 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 flow 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 flow and reduces on/off cycling of the pump by lessening the pressure variation. It also gives better control of hot water temperature for showers.
