Groco WSC-80 12V Self-Priming Water Pressure System with PST-1
The Groco WSC-80 12V Self-Priming Water Pressure System with PST-1 represents premium engineering for applications requiring reliable, consistent water delivery. This heavy-duty system combines a powerful 12-volt self-priming vane pump with a 2-gallon pressurized accumulator tank (PST-1) to deliver impressive 7.5 GPM flow rates with exceptional pressure stability. The self-priming capability ensures immediate operation without pre-filling, making it ideal for remote locations and continuous-duty applications where water availability is critical.
Built with commercial-grade components, the WSC-80 system features precise pressure control mechanisms and low-water shut-off protection to safeguard both the pump and connected systems. The positive-displacement vane pump design delivers consistent flow across varying demand levels, while the PST-1 accumulator tank reduces cycling frequency and extends pump life through shock absorption. This complete water pressure solution is engineered for both marine and land-based applications including deck washing, fresh water systems, RV water supplies, and industrial wash-down operations.
The system's robust construction and proven reliability make it the preferred choice for boat owners, RV enthusiasts, and facilities managers who demand dependable water delivery performance. With minimal maintenance requirements and simple 12-volt DC operation, the Groco WSC-80 12V system provides years of trouble-free service in demanding environments where other systems fail.

Frequently Asked Questions
Q: Is the Groco WSC-80 12V system truly self-priming or does it require pre-filling?
The WSC-80 features genuine self-priming capability, meaning it can extract water from the source without requiring manual pre-filling of the pump chamber, provided the inlet line is submerged or has access to water within the priming lift height limitations.
Q: What is the maximum lift height for self-priming operation from the water source?
The self-priming capability typically allows for lift heights up to approximately 6-8 feet from the water source surface, though actual performance depends on water temperature, atmospheric pressure, and installation configuration.
Q: Can the PST-1 accumulator tank be replaced or serviced if it fails?
Yes, the PST-1 accumulator tank is a separate component that can be individually replaced without replacing the entire pump system, making repair and maintenance more economical over the product lifecycle.
Q: What power supply and wiring gauge are recommended for the 12V WSC-80 system installation?
A dedicated 12-volt DC power supply with appropriate amperage capacity (typically 15-30 amps depending on motor specifications) and properly sized marine-grade electrical wiring is essential, with installation by qualified electricians recommended for marine applications.
Q: Is the Groco WSC-80 12V suitable for both freshwater and saltwater marine environments?
The system is designed for freshwater applications and can handle temporary saltwater exposure, though regular freshwater rinsing after saltwater contact and proper maintenance protocols are essential to prevent corrosion and ensure long-term reliability in coastal environments.
