05 Water Pressure Systems INTRODUCTION Pressure Controlled Diaphragm Pumps Pressure controlled diaphragm pumps provide boat owners with a fresh water system that is as easy to use as their domestic water supply – with the versatility to offer full ow or a trickle. The pump is controlled by a switch which senses the pressure drop when a faucet is opened and activates the pump; it turns off when the system pressure builds to a pre-set limit as the faucet is closed. This system allows any type of faucet or shower valve to be tted, from ³⁄8” (10mm) bore for minimum water use to ½” (13mm) bore for maximum ow. Choosing the pump for your needs is simple – just check your system size and the number of outlets you need to operate simultaneously and select the appropriate pump. Diaphragm pumps are self-priming, quiet in operation and can run dry for extended periods. It is always best to turn the pump off and then open a tap to de-pressurize the system when you are not using the boat as this will prolong pump life. Accumulator Tanks Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pump and pressure uctuations, smoothing the ow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot water delivery. Our accumulator tanks all have a bladder that separates water from air. The bladder is prepressurised but may need ne tuning when installed to give the most efcient performance. One of the advantages of an accumulator tank is that they can dispense up to half of their capacity of water even when the pump is switched off. So the bigger the reservoir, the more water you have available without having to switch the pump on helping you wash your hands or clean your teeth without noise. Water Pressure Regulators Inlet water regulators are designed to protect your boat water system plumbing and xtures from the possible high pressure of municipal water systems. Regulation is controlled at all ow rates by a pre-set spring and removable strainer traps debris. Both inline portable and permanent ush mount models are available in our new line of diaphragm sealed regulators.

053 It probably goes without saying that many Jabsco pumps have more than one possible application. Sometimes it is a simple matter of installing the standard product in the different application. Sometimes Jabsco needs to develop the standard product to meet the particular needs of the different application. Washdown Pumps Washdown pumps are a development of our Water Pressure System pumps. Higher shut-off pressure switches prevent on/off cycling while salt water compatible trigger nozzles let you blast off mud and dirt, and then rinse down. Pumpgard™ Strainers Inlet Strainers are an...
