The rings maintain compression and limit bypass between the piston and cylinder bore, which directly affects pumping efficiency and output volume. On walk-behind trowel models CT30ADT and CT30ADT-E, the set fits at the Piston assembly location. Worn or broken piston rings typically present as reduced suction or discharge pressure, increased internal leakage, or irregular pump cycling. Replacing the full ring set together rather than individual rings ensures uniform sealing across all ring grooves and avoids mismatched wear profiles. This set is the appropriate service item when rebuilding the piston assembly during scheduled overhaul or after inspection reveals ring wear, scoring, or loss of tension.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCT30ADT\u003c\/li\u003e\n\u003cli\u003eCT30ADT-E\u003c\/li\u003e\n\u003cli\u003ePDI2A(I)\u003c\/li\u003e\n\u003cli\u003ePDI3A\u003c\/li\u003e\n\u003cli\u003ePDI3A(I)\u003c\/li\u003e\n\u003cli\u003ePDT2A\u003c\/li\u003e\n\u003cli\u003ePDT3A\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":43398708625456,"sku":"WACKER-5100028594","price":81.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100028594.jpg?v=1784071114","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-piston-ring-set-5100028594-for-diaphragm-pumps","provider":"CCE Industries","version":"1.0","type":"link"}
