{"product_id":"337030000","title":"Multiquip 337030000 Diaphragm - OEM Replacement Part for MQD2HA\/D3HA Diaphragm Pumps","description":"\u003cp\u003eThe diaphragm is the core pumping component in the MQD2HA and MQD3HA diaphragm pump series, creating the reciprocating action that moves water through the system. This critical component is protected by the plunger guard and works in conjunction with the connecting rod bearing assembly to transfer power from the gearbox to create suction and discharge pressure. Regular inspection and replacement of the diaphragm is essential to maintain pump performance and prevent failures that could affect priming capability and discharge pressure.\u003c\/p\u003e\n\n\u003cp\u003eLocated within the waterbox assembly under the plunger guard, the diaphragm is part of the pump components that should be monitored during the monthly maintenance cycle when greasing the connecting rod bearing. Signs that diaphragm replacement is needed include loss of priming ability, reduced discharge pressure, suction leaks at the inlet, or visible damage during inspection. This OEM replacement ensures proper fit and operation with the MQD2HA and D3HA pump series.\u003c\/p\u003e\n\n\u003cp\u003eCompatible Models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMQD2HA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Multiquip OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Multiquip","offers":[{"title":"Default Title","offer_id":43066049200176,"sku":"337030000","price":232.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/337030000.png?v=1779813806","url":"https:\/\/cce-industries.com\/products\/337030000","provider":"CCE Industries","version":"1.0","type":"link"}
