The Multiquip EM97086 Piston Pump is a genuine OEM component designed for the ST-70 submersible pump. As a factory-authorized replacement part, it is manufactured to the same specifications as the original, ensuring a direct fit and consistent pumping performance. This part is confirmed compatible with ST-70 series submersible pumps, making it the dependable choice when restoring full pump operation.
Key Features
- Genuine OEM Construction — Manufactured to the original design tolerances, delivering the correct displacement and sealing integrity expected of a piston-driven pump component.
- Direct-Fit Replacement — Engineered to install directly into ST-70 submersible pump assemblies using the existing mounting configuration, with no reworking of surrounding components.
- Confirmed ST-70 Compatibility — Verified fitment for the Multiquip ST-70 submersible pump series, so you can order with confidence.
- Sustained Pumping Pressure — A correctly functioning piston pump maintains the consistent pressure and flow rate the ST-70 depends on to move water efficiently; a worn piston leads to pressure loss and reduced output.
- Fluid System Integrity — Proper piston fit and seal condition are critical in submersible applications where internal leakage or bypass directly compromises pump efficiency and motor load.
The piston pump is the core fluid-moving component within the pump assembly, using reciprocating piston action to draw in and displace water or fluid under pressure. In submersible pump applications, this component must maintain tight tolerances to prevent internal bypass, which would reduce output flow and place added strain on the motor. When the piston or its associated seals wear, the pump loses prime efficiency, output drops noticeably, and continued operation can accelerate wear throughout the assembly.
