Its pre-assembled components — including the volute, impeller, wear ring, mechanical seal, suction cover, O-rings and drain plug — follow the Executive wet end’s original OEM-style layout for dependable alignment and operation. The discharge can be rotated in 90-degree increments, making it easier to configure during rebuilds or when upgrading equipment. With materials built to handle chemical-treated water and repeated heat cycles, the 310-1890 offers a long-lasting replacement for Executive-series wet ends.\u003c\/p\u003e\n\u003ch3 data-start=\"2854\" data-end=\"2872\"\u003e\u003cstrong data-start=\"2858\" data-end=\"2872\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"2873\" data-end=\"3614\"\u003e\n\u003cli data-start=\"2873\" data-end=\"3027\"\u003e\n\u003cp data-start=\"2875\" data-end=\"3027\"\u003e\u003cstrong data-start=\"2875\" data-end=\"2903\"\u003e2 HP \/ 48-Frame Fitment:\u003c\/strong\u003e Designed for 2 HP motors with 2 inch inlet and outlet connections to keep system flow and pressure consistent under load.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3028\" data-end=\"3175\"\u003e\n\u003cp data-start=\"3030\" data-end=\"3175\"\u003e\u003cstrong data-start=\"3030\" data-end=\"3058\"\u003eConvenient Pre-Assembly:\u003c\/strong\u003e Comes with all major components installed, reducing rebuild steps and helping ensure correct mechanical alignment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3176\" data-end=\"3317\"\u003e\n\u003cp data-start=\"3178\" data-end=\"3317\"\u003e\u003cstrong data-start=\"3178\" data-end=\"3212\"\u003eFlexible Plumbing Orientation:\u003c\/strong\u003e Adjustable 90-degree discharge allows technicians to match existing plumbing layouts more efficiently.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3318\" data-end=\"3473\"\u003e\n\u003cp data-start=\"3320\" data-end=\"3473\"\u003e\u003cstrong data-start=\"3320\" data-end=\"3351\"\u003eExecutive-Grade Durability:\u003c\/strong\u003e Made to withstand thermal cycling, water chemistry and mechanical stress encountered in heavy-use pool and spa systems.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3474\" data-end=\"3614\"\u003e\n\u003cp data-start=\"3476\" data-end=\"3614\"\u003e\u003cstrong data-start=\"3476\" data-end=\"3508\"\u003eIdeal Executive Replacement:\u003c\/strong\u003e Works as a direct upgrade for older Executive wet ends, supporting a smooth return to proper performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"2843\" data-end=\"2864\"\u003eAdditional Info\u003c\/h3\u003e\n\u003cp data-start=\"2865\" data-end=\"3184\"\u003eThe Waterway 310-1890 Executive Wet End is a durable, high-flow replacement for 2 HP 48-frame motors commonly serviced by local technicians.
