Adequate space should be provided for routine maintenance such as oil changes and belt adjustments. For best performance, place the pump as close as possible to the vacuum system to minimize tubing length and maximize efficiency.\u003c\/p\u003e\n\u003cp\u003eWelch vacuum complete pumps model numbers include a four number model of pump along with a suffix containing a letter, dash and two numbers to designate voltage. The complete pump (pump, motor, base, belt - ready to run out of the box) in 115v, 60 Hz is a Welch 1402B -01 vacuum pump.\u003c\/p\u003e\n\u003cp\u003eThe Welch catalog#: 1402 is a base pump only. It is an unmounted pump typically used for a drop in replacement for a failed pump. The Welch 1402 cat# does not include the base, belt or motor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOur \u003ca href=\"https:\/\/www.chemtechsci.com\/blogs\/news\" title=\"Chemtech Scientific Blog\" rel=\"noopener\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eBlog\u003c\/span\u003e\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Welch","offers":[{"title":"Default Title","offer_id":1127839496,"sku":"1402B-01","price":3669.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/2467\/products\/welch-1402b-01-duoseal-vacuum-pump-25487941632149.jpg?v=1779794251","url":"https:\/\/www.chemtechsci.com\/products\/welch-1402b-01-duoseal-vacuum-pump","provider":"Chemtech Scientific Incorporated","version":"1.0","type":"link"}
