The auxiliary pump works alongside the primary pump circuit to maintain oil flow through the return and supply loops, supporting the overall heating system operation as described in Wacker Neuson's pump and valve layout for the E3000 platform.\u003c\/p\u003e\n\n\u003cp\u003eWacker Neuson hydronic heaters use multiple pumps to manage fluid circulation across independent loops. The auxiliary pump handles return flow duties separate from the main loop pumps, and its assembly position at the oil filter places it within the filtration and circulation circuit. A failed or worn auxiliary pump can disrupt return flow through the system, which may register at the auxiliary return flow indicator on the control panel.\u003c\/p\u003e\n\n\u003cp\u003eThis part is sourced directly from Wacker Neuson and carries the official part number 5100056484. It is manufactured to the same specifications as the pump originally installed at the factory, ensuring correct fit within the oil filter assembly location.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWacker Neuson E3000\u003c\/li\u003e\n\u003cli\u003eWacker Neuson E3000 (5100056441)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398892486704,"sku":"WACKER-5100056484","price":391.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100056484.jpg?v=1784080285","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-auxiliary-oil-pump-5100056484-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
