FAQ
What makes the GROCO PJR-B 24V different from standard pressure pumps?
The PJR-B 24V uses a heavy-duty bronze rotary pump capable of delivering higher flow rates and longer operational life compared to many standard diaphragm-style pressure pumps.
Can this system be used outside marine environments?
Yes. Although commonly installed in yacht water systems, it is also suitable for RVs, industrial equipment, utility trailers, commercial washdown systems, and mobile service applications.
Does the system include dry-run protection?
Yes. GROCO’s patented NOFLO protection technology automatically shuts down the system during low-water or dry-run conditions to help protect the pump.
Is the pressure tank included?
Yes. The PJR-B 24V includes an integrated 2-gallon pressure storage tank for smoother water delivery and reduced pump cycling.
What type of fluids can this pressure system handle?
The unit is designed primarily for freshwater and low-solids non-flammable liquids compatible with bronze pump construction.
Is professional installation recommended?
Professional installation is recommended to ensure proper electrical wiring, plumbing support, pressure settings, and long-term performance.
