Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional spec of the original valve, ensuring proper sealing force and flow-direction control specific to Multiquip submersible pump applications.
- Direct-Fit Installation — Matches the original mounting configuration on ST2038P and ST2037 models, dropping into place without rework or adaptation to the pump housing.

- Prevents Backflow and Pressure Loss — A correctly functioning check valve maintains discharge pressure and stops water from flowing back through the pump when it cycles off, protecting internal components from reverse-flow stress.
- Authorized Multiquip Source — Sold by DHS Equipment as a genuine Multiquip OEM part, backed by the manufacturer's parts program for traceability and quality assurance.
A check valve is a one-way flow control component that allows fluid to pass in a single direction while preventing reverse flow back through the pump. In a submersible pump, it plays a critical role in maintaining discharge line pressure and protecting the pump's internal components from backflow surges when the unit stops. When a check valve wears, cracks, or fails to seat properly, water can siphon back through the system, causing the pump to lose prime, cycle inefficiently, or suffer premature wear on seals and impellers.
