It is used to rebuild the pump head section, so it suits repairs where the existing pump motor is still in place and the service parts in the wet end need to be renewed.\u003c\/p\u003e\u003cp\u003eThis kit matches PAR-MAX pump families used on 12Vdc and 24Vdc onboard freshwater systems, including 3.5 GPM 31600-series pumps and 4.3 GPM 31620-series pumps. These pumps are commonly used in self-contained boat water systems feeding sinks, showers, and similar domestic outlets, so the main fit point to confirm is the series number on the pump already installed.\u003c\/p\u003e\u003cp\u003eThe service kit covers the core wear items in the pump head, including the valve set, diaphragm set, lower housing service pieces, and slide clips. That makes it a sensible option when you want to restore pump function without changing the full pump assembly or disturbing the existing wiring and plumbing layout more than necessary.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eFits Jabsco PAR-MAX 31600-series and 31620-series freshwater pressure pumps\u003c\/li\u003e\n\u003cli\u003eWorks with both 12Vdc and 24Vdc versions within those pump families\u003c\/li\u003e\n\u003cli\u003eSupports PAR-MAX pump sizes rated at 3.5 GPM and 4.3 GPM in these series\u003c\/li\u003e\n\u003cli\u003eCovers the main service parts in the pump head, including valve, diaphragm, lower housing service pieces, and slide clips\u003c\/li\u003e\n\u003cli\u003eUseful for keeping an onboard freshwater pressure system in service without replacing the complete pump\u003c\/li\u003e\n\u003cli\u003eSuited to boat water systems serving galley, head, and shower outlets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis kit is intended for Jabsco PAR-MAX freshwater delivery pumps in the 31600 and 31620 series. Those pump families use a multi-chamber diaphragm layout and were sold in both 12Vdc and 24Vdc versions, so voltage alone is not the fit point for this kit. Match the pump series on the label before ordering.\u003c\/p\u003e\u003cp\u003eIt is a good match for owners maintaining the original pressure pump on a cruising boat, sailboat, or small motorboat where the freshwater system is already built around a PAR-MAX pump in one of these series. It is not a complete replacement pump, so it suits service work on an existing installation rather than a new system build.\u003c\/p\u003e\u003ch6\u003eInstallation and service\u003c\/h6\u003e\u003cp\u003eService work starts with power disconnected and system pressure relieved by opening a faucet or valve. Because this kit rebuilds the pump head section, it is most useful when the pump body and motor are staying in place and you are addressing wear in the valve and diaphragm area.\u003c\/p\u003e\u003cp\u003eOn a boat, that usually means less disruption than changing the whole pump, especially where hose runs, wiring access, and mounting space are tight. It is a practical maintenance item to keep aboard when the vessel depends on a PAR-MAX pressure pump for everyday freshwater use.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eValve kit\u003c\/li\u003e\n\u003cli\u003eDiaphragm kit\u003c\/li\u003e\n\u003cli\u003eLower housing service pieces\u003c\/li\u003e\n\u003cli\u003eSlide clips\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Jabsco","offers":[{"title":"Default Title","offer_id":52581868896437,"sku":"QBP172435","price":217.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1330174_qbp172435.webp?v=1780200959","url":"https:\/\/www.qualityboatparts.com\/products\/qbp172435","provider":"Quality Boat Parts","version":"1.0","type":"link"}
