Description

The Shurflo 8000-543-238 is a high-pressure 12V DC diaphragm pump from the 8000 Series, specifically engineered for high-performance spraying and delivery tasks. This model is often referred to as the “industry standard” for 12V spot sprayers due to its ability to reach 100 PSI while maintaining a consistent flow.

The “(6)” indicates a bulk/case quantity of six pumps.

Technical Specifications

Key Features

• High-Pressure Output: Unlike standard 12V pumps that cap out at 40–60 PSI, this model reaches 100 PSI, providing the “reach” needed for tall tree spraying or long-distance hose runs.

• Automatic Demand Switch: The built-in pressure switch is factory-set to 100 PSI. It shuts the motor off completely when the discharge is closed (nozzle off) and restarts it instantly upon trigger pull.

• Chemical Compatibility: Features EPDM valves and a Santoprene diaphragm, making it highly resistant to many water-based fertilizers, herbicides (including glyphosate), and mild detergents.

• Self-Priming: Capable of a vertical suction lift of up to 8 feet (2.4m), allowing the pump to be mounted on top of tanks or inside vehicle compartments without requiring a gravity feed.

• Internal Bypass: Designed to handle higher pressures without excessive “cycling” (chattering), which helps protect the motor and pressure switch during operation.

Ideal Applications

• Professional Spot Spraying: Ideal for UTV/ATV-mounted sprayers used for fence lines, invasive species control, and landscape maintenance.

• Agricultural Booms: Can support small boom setups or boomless nozzles that require higher pressure to achieve proper spray patterns.

• Soft Washing: Frequently used as a dedicated application or rinse pump in light-duty professional soft wash systems.

• Industrial Fluid Transfer: Suitable for moving fluids in environments where 12V battery power is the only available source.
