This makes the class not only more compactly, but also lighter. The JDK-S-500 also comes with a pre-set pressure relief valve.\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0269\/2035\/3881\/files\/Manual-SECOH-en-JDK-150-500_2.pdf?v=1674652041\" title=\"Install instructions Secoh JDK-S-300\" target=\"_blank\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"bodytext\"\u003e\u003cb\u003eLong life expectancy\u003c\/b\u003e \u003cbr\u003eMotor and pump parts are combined in one single construction.
