Remco 5.3 GPM Demand Pump 12 VDC — 3/4" Quick Attach, 60 PSI, Santoprene Diaphragm

Built from heavy-duty components in the U.S.A., the Remco 5500 Series pump delivers consistent flow, low operating temperature, and chemical compatibility for herbicides, fertilizers, insecticides, and other liquid transfer tasks. Its sealed motor, Santoprene diaphragm and Viton valves make it suitable for demanding duty cycles, while 14 AWG wire leads and a compact footprint simplify installation on sprayers, utility vehicles, and equipment wash stations.

How does this pump perform under continuous agricultural use?

The 5.3 GPM demand mode keeps spray pressure near 60 PSI while minimizing motor heat, helping the pump run efficiently during repeated cycles. Designed for intermittent duty, the pump handles long sessions typical of field spraying and equipment cleaning.

• 5.3 GPM (20.06 LPM) maximum flow at demand operation
• 60 PSI (4.1 Bar) operating pressure setting for consistent spray patterns
• Sealed 12 VDC motor reduces exposure to dust and moisture
• Low heat generation and lower power consumption compared to similar models

What chemicals and liquids is the Remco pump compatible with?

Materials were selected for broad compatibility with common agricultural chemicals without sacrificing durability. The Santoprene diaphragm and Viton valves resist degradation from many herbicides, fertilizers, and insecticides, while construction tolerates fluids used for washdown and fluid transfer.

• Viton valves for improved chemical resistance
• Santoprene diaphragm for long service life with chemical sprays
• Suitable for liquid fertilizer, herbicide, insecticide, and wash fluids
• Not for use with unknown or highly reactive chemicals without testing

How do I install and connect the Remco 5517-1E1-82B on my vehicle or sprayer?

Installation is straightforward: secure the pump to a stable mount, connect 12 VDC power with the supplied 14 AWG leads and SAE 2-pin connector, and attach 3/4" quick attach hoses. Self-priming capability and quick attach ports reduce setup time in the field.

• 6" length 14 AWG wire leads with SAE 2-pin connector (also available in 12" option)
• 3/4" quick attach fluid ports for rapid hose connection
• Self-priming up to 14' (4.0 m) vertical lift
• Observe maximum liquid and motor temperature limits for safety

What service and operating limits should I watch for?

The pump supports intermittent duty cycles and can run dry briefly, but the motor lacks internal thermal protection. Keep liquid temperatures below 140°F (60°C) and monitor motor surface temperature to stay under recommended limits for longevity.

• Maximum liquid temperature: 140°F (60°C)
• Maximum motor surface temperature: 180°F (82°C); optimal under 150°F (66°C)
• Dry-run capability for short intervals, not continuous dry operation
• 100% factory tested prior to shipment

Who is this for? The Remco 5.3 GPM Demand Pump is aimed at professionals and serious equipment owners who need a durable, efficient 12 V pump for agricultural spraying, liquid fertilizer transfer, equipment washdown, dust suppression, or automotive fluid exchange. It fits service technicians, contractors, and farmers looking for a U.S.-made, chemically compatible diaphragm pump that balances high flow with low operating temperature. If you require continuous 24/7 operation or have unusual chemical requirements, consult Remco specifications or technical support to confirm suitability before purchase.
