Pumpoasis 12V Diaphragm Sprayer Pump 5.4 GPM, 60 PSI — Chemical-Resistant, Self-Priming with Pressure Switch

This compact 12V pump combines a corrosion-resistant diaphragm, an all-copper motor, and an integrated pressure switch to provide a dependable flow for soft-wash, garden irrigation, RV water supply, and light agricultural spraying. Built for compatibility with common solutions (including Roundup) and equipped with inlet filtration, it balances power and longevity for mobile and stationary applications.

How much flow and pressure can I expect from this pump?

The Pumpoasis pump delivers up to 5.4 gallons per minute and can be adjusted from 0 to 60 PSI to match your spraying needs. An automatic pressure switch stops and restarts the motor to maintain set pressure, reducing wear from continuous operation.

• Maximum flow: 5.4 GPM (gallons per minute)
• Adjustable pressure range: 0–60 PSI
• Auto shutoff via built-in pressure switch to preserve motor life
• Operating current ~10 amps under typical loads

Is this pump safe for chemical use and long-term outdoor service?

This diaphragm pump is built with chemical- and corrosion-resistant materials designed to handle many agricultural and cleaning solutions without rapid degradation. The unit includes overheat protection and a leak-proof integrated housing to extend service life in demanding environments.

• Chemical-resistant diaphragm compatible with common herbicides and cleaners
• All-copper motor and sealed construction for durability
• Overheat protection halts operation and restarts automatically after cooling
• Built-in inlet filter shields internal components from debris

Can the pump self-prime and what fittings are included?

Pumpoasis designed this pump to self-prime up to 10 feet, with a maximum lift head around 114 feet, making it suitable for drawing from small tanks or portable containers. It ships with 1/2" and 3/4" hose adapters so you can connect common garden hoses, sprayer lines, or inline fittings quickly.

• Self-priming height: up to 10 feet
• Lift head capability: approximately 114 feet
• Included adapters: 1/2" and 3/4" hose fittings for broad compatibility
• Use recommended plumbing to avoid frequent pressure switch cycling

How should I install and maintain this pump for best results?

Install the pump on a stable, vibration-damped surface and keep inlet and outlet plumbing balanced to prevent rapid switch cycling. Regularly inspect the inlet filter, hoses, and connections for wear or clogging and flush the pump after use with compatible clean water when switching chemicals.

• Mount on a rubber or vibration-isolating pad for quiet operation
• Keep inlet/outlet hose diameters consistent to reduce cycling
• Check and clean inlet filter periodically to prevent debris damage
• Flush pump before storing or when changing fluids

Who is this for: The Pumpoasis 12V Sprayer Pump is aimed at homeowners, landscapers, and small-scale farmers who need a portable, chemical-tolerant pump for spray applications, RV and boat water systems, and soft-wash or irrigation tasks. It is also a practical choice for contractors and DIY users seeking a compact, self-priming diaphragm pump with adjustable pressure, robust materials, and basic overheat protection for reliable daily use.
