Pumpoasis 12V Sprayer Pump 2.5 GPM, 60 PSI — Chemical‑Resistant Diaphragm with Pressure Switch

Pumpoasis 12V Sprayer Pump is a compact, self-priming diaphragm pump delivering 2.5 GPM and up to 60 PSI for chemical-resistant spraying, RV water systems, and light agricultural duties.

This rugged 12-volt sprayer blends durable materials with automatic pressure control to handle a wide range of outdoor and mobile water tasks. Built with corrosion-resistant components, a copper motor, and an integrated pressure switch, it supports liquid transfer, soft wash, and on-board water supply applications. Self-priming capability and built-in safety features make it suitable for variable field conditions and intermittent use.

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

The Pumpoasis pump produces about 2.5 gallons per minute and can reach a maximum of 60 PSI. A pressure-adjustable switch allows the unit to stop automatically near the set point, conserving power and reducing wear when not required.

• Rated flow: approximately 2.5 GPM for steady spray operation
• Pressure range: 0–60 PSI adjustable via the internal switch
• Automatic shutoff prevents unnecessary cycling and extends life

Can this handle chemicals and corrosive solutions?

This diaphragm pump uses chemical-resistant materials designed to tolerate a variety of liquid formulations, including many common herbicides and cleaning agents. A sealed, leak-resistant housing and an inlet filter help protect internal parts from contaminants.

• Corrosion-resistant diaphragm compatible with many solutions
• Leak-proof construction minimizes exposure to harsh liquids
• Built-in inlet filter blocks debris that could damage the pump

What mounting and installation features help in vehicles or boats?

Designed for mobile and stationary setups, the pump includes a rubber noise-damping base for quieter operation and multiple hose adapter sizes to match common fittings. Its 12V DC operation makes it straightforward to install in RVs, boats, ATVs, and off-grid rigs.

• 12V DC power compatible with typical vehicle and marine systems
• Noise-dampening rubber base for stable, low-vibration mounting
• Includes 1/2" and 3/4" adapters for flexible hose connections

How reliable is it for long-term or seasonal use?

The pump was engineered for extended service life using robust components such as an all-copper motor and thermal protection. Overheat protection pauses operation during high-load conditions and restarts automatically after cooling, reducing risk of damage from prolonged runs.

• Copper motor provides durability and consistent performance
• Overheat protection prevents motor burnout and restarts when safe
• Expected long service life when used and maintained properly

Who is this for: Pumpoasis's 12V sprayer is aimed at homeowners, landscapers, and mobile-application users who need a compact, chemical-tolerant pump for spraying, soft-wash, RV water systems, and light agricultural tasks. It suits anyone seeking a balance of portability, adjustable pressure, and corrosion resistance for seasonal or regular outdoor use.
