The switch remains closed at 5 PSI or higher; when pressure drops below 5 PSI, it opens and cuts power to protect the pump.\u003c\/p\u003e\u003cp\u003eFor delivery (demand) pump applications using a pressurized bladder tank (such as an RO tank), an LPS is recommended to shut off the pump if the tank runs empty. This helps prevent damage to the tank bladder and avoids cavitation. In these setups, the tank pre-charge is typically reduced to around 1 PSI to maximize water storage capacity.\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecifications:\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial: \u003c\/b\u003eWetted parts are FDA Approved or NSF listed\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eConnection:\u003c\/b\u003e 1\/8\" Male NPT thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePressure Switch Closed:\u003c\/b\u003e @ 5 PSI or more\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePressure Switch Opened:\u003c\/b\u003e 1 - 5, Preset @ 2.3 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eElectrical: \u003c\/b\u003e125 - 250 VAC, 15A Max.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePower: \u003c\/b\u003eCompatible with 110V or 220V transformers\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSustained Operating Pressure: \u003c\/b\u003e50 PSI Max.\u003c\/li\u003e\n\u003cli\u003eTop Terminal: Common Lead\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMiddle Terminal: \u003c\/b\u003eNormally Open Lead\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBottom Terminal: \u003c\/b\u003eNormally Closed Lead\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAccessories: \u003c\/b\u003eWire Harness to connect to pump and transformer\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Aquatec","offers":[{"title":"Box of 5","offer_id":47774299685015,"sku":"LPS340-G-21-028 KIT:5PK","price":117.7,"currency_code":"USD","in_stock":true},{"title":"Box of 25","offer_id":47774299717783,"sku":"LPS340-G-21-028 KIT:25PK","price":588.5,"currency_code":"USD","in_stock":true},{"title":"Box of 50","offer_id":47774299750551,"sku":"LPS340-G-21-028 KIT:50PK","price":1178.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0416\/1440\/9879\/files\/gzxn8zcrodxtrqwozag9.jpg?v=1780579311","url":"https:\/\/neosupply.com\/products\/low-pressure-shut-off-switch-1-8-male-npt-with-wire-harness-for-lps340-g-21-028-kit","provider":"NeoSupply","version":"1.0","type":"link"}
