The Multiquip EM98027 O-Ring Pump ST70 is a genuine OEM O-Ring designed for the ST70 submersible pump. This factory-sourced seal component delivers the precise material grade and compression profile required to maintain a leak-free pump assembly on ST70 equipment. As an authentic Multiquip OEM part, the part is manufactured to the exact specification of the original component, ensuring correct fitment and long-term sealing integrity. If your ST70 is showing signs of fluid leakage or seal degradation, replacing the O-Ring with the genuine EM98027 restores proper pump function quickly and correctly.
Key Features
- Genuine OEM Sealing Material — Manufactured to the exact elastomer compound and dimensional spec of the original, ensuring the correct compression set and resistance to water and pump fluid exposure.
- Drop-In Seal Replacement — Seats directly into the pump housing groove on the ST70 with no trimming, stretching, or modification — the profile matches the original channel precisely.
- Confirmed ST70 Compatibility — Specifically matched to the ST70 submersible pump, so you can order with confidence knowing this is the correct seal for your machine.
- Leak Prevention at the Source — A properly seated O-Ring keeps pump internals pressurized and fluid contained, protecting motor components from water intrusion and maintaining full pumping efficiency.
- Fuel and Fluid Seal Integrity — In submersible pump applications, a compromised O-Ring can allow water ingress into sealed cavities, leading to motor damage or loss of prime — replacing it promptly avoids costly downstream repairs.
The O-Ring in a submersible pump serves as the primary seal between mating pump housing components, preventing water or fluid from bypassing the sealed cavity during operation. When this seal is in good condition, the pump maintains proper internal pressure and keeps contaminants away from sensitive internal parts. As the O-Ring ages or is exposed to prolonged use, it can harden, compress permanently, or crack — allowing leaks that reduce pump performance and risk damage to the motor or housing over time.
