The Multiquip EM16819 Seal is a genuine OEM seal designed for the ST-70 submersible pump. As a direct OEM replacement, EM16819 meets the original engineering specifications set by Multiquip, ensuring a proper fit within the pump assembly without guesswork or modification. This seal is sourced directly through Multiquip's authorized parts network, making it the correct choice for technicians and operators maintaining ST-70 equipment. Confirm your model against your equipment documentation before ordering to ensure compatibility.
Key Features
- Genuine OEM Material Integrity — Manufactured to Multiquip's original compound and dimensional specifications, delivering the compression characteristics required for a leak-free seal in submersible pump applications.
- Drop-In Fit for ST-70 — Engineered to seat directly into the original seal housing on the ST-70 submersible pump, eliminating the need for improvised solutions during service.
- ST-70 Verified Compatibility — Confirmed fitment for Multiquip ST-70 submersible pump models, so you can order with confidence against your equipment's parts list.
- Maintains Pump Integrity Under Load — A properly seated seal prevents water ingress into critical pump components and keeps internal pressure stable, allowing the ST-70 to transfer water efficiently at rated capacity.
- Leak Prevention and Electrical Safety — In a submersible pump application, a compromised seal can allow water to reach motor windings and electrical components — replacing a worn seal promptly protects both the pump and the operator.
A seal in a submersible pump serves as the primary barrier between the wet end of the pump and its internal mechanical and electrical components. It prevents water from migrating along the shaft or through housing joints into areas where moisture would cause corrosion, shorts, or bearing damage. When a seal wears, cracks, or loses its compression set, leakage can develop gradually — often going unnoticed until significant internal damage has occurred. Replacing the seal at the first sign of weeping or during scheduled service intervals is the most effective way to extend the working life of the pump.
