Ultra-efficient motor with fan cooling
High-volume liquid transfer capability
Continuous flow with pressure regulation
Up to 14 feet vertical suction lift
5-Chamber Positive Displacement Design: The Zeus pump uses a 5-chamber diaphragm configuration that delivers smoother flow with less pulsation compared to 3-chamber designs. This results in more consistent pressure, reduced system stress, and better spray pattern uniformity.
Self-Priming Capability: The pump can lift liquids up to 14 feet vertically, making it ideal for applications where the pump is mounted above the liquid source. No need for complex priming systems or gravity feed arrangements.
Dry Run Capable: The pump can run dry without damage, providing protection against accidental dry running and reducing maintenance concerns in automated systems.
The 9559-2E5-971 features bypass operation, which continuously circulates liquid through the system even when spray tips are closed. This provides several advantages: • Constant Pressure: Maintains consistent pressure for uniform spray patterns • Reduced Cycling: Motor runs continuously rather than cycling on/off • Temperature Control: Continuous flow helps dissipate heat from pump and motor • System Flushing: Keeps lines clear of sediment and chemical buildup • Extended Pump Life: Reduces wear from constant start/stop cycling
24V DC Ultra-Efficient Motor: The Zeus pump uses a precision-engineered 24V DC motor that delivers maximum power while minimizing current draw. This high-efficiency design reduces battery drain and allows for longer operating periods.
Integrated Fan Cooling: The heavy-duty cooling fan and aluminum heatsink keep the motor temperature within safe operating limits even during extended duty cycles. This thermal management system extends motor life and maintains consistent performance.
Extended Duty Cycle: Designed for 1+ hour continuous duty cycles, making it suitable for large-scale applications and commercial operations where downtime isn't an option.
Polypropylene Housing: Resists most agricultural chemicals, fertilizers, and industrial liquids. Won't crack, corrode, or degrade from chemical exposure. Viton Valves: High-performance fluoroelastomer valves provide excellent chemical resistance and maintain sealing integrity over thousands of cycles. Santoprene Diaphragms: Advanced thermoplastic elastomer diaphragms resist chemicals, maintain flexibility in temperature extremes, and provide long service life. Stainless Steel Fasteners: All hardware uses stainless steel to prevent corrosion and maintain structural integrity.
Agricultural & Turf Spraying: Herbicides, pesticides, fungicides, fertilizers, and growth regulators. Perfect for boom sprayers, spot spraying, and precision application systems.
Industrial Spraying: Concrete sealers, mold release agents, cleaning chemicals, and industrial coatings. Handles viscous liquids and aggressive chemicals with ease.
Fertilizer Transfer & Application: Liquid fertilizer injection, starter fertilizer application, and nutrient solution delivery for hydroponic and greenhouse systems.
Road Maintenance: Dust suppressants, ice melt solutions, line marking paint, and asphalt sealers. Built to handle the demands of municipal and highway maintenance operations.
Washdown & Cleaning: High-pressure washdown systems, sanitizing solutions, and industrial cleaning applications. Ideal for food processing, dairy operations, and equipment cleaning.
Deicing Systems: Liquid deicing agents for airports, bridges, and critical infrastructure. Handles corrosive deicing chemicals without degradation.
Electrical Requirements: • 24V DC power supply (battery or converter) • 50 amp fuse protection recommended • 10 AWG 12" lead wires included Plumbing Connections: • 1" FNPT (Female National Pipe Thread) inlet and outlet • Standard pipe fittings and adapters available • Hose barb and camlock adapters recommended Operating Limits: • Maximum liquid temperature: 140°F (60°C) • Maximum motor shell temperature: 180°F (82°C) • Self-priming height: Up to 14 feet vertical lift
Mounting Options: The pump includes mounting brackets for secure installation on spray rigs, trailers, or stationary applications. The compact 8-pound design makes it easy to integrate into existing systems.
Wiring: Pre-wired with 12" leads using 10 AWG wire suitable for the high current draw. Connect positive to 24V supply through a 50-amp fuse, negative to ground/return.
Plumbing: 1" FNPT connections accept standard pipe fittings. Use appropriate hose sizes (minimum 3/4" recommended) and ensure inlet filtration to prevent debris damage.
This pump is NOT intended for soft wash applications. Using soft wash chemicals (sodium hypochlorite, etc.) in this pump will void the warranty. The standard Zeus model is designed for agricultural and industrial chemicals, not the highly corrosive bleach solutions used in soft washing. For soft wash applications, consider the Zeus SmoothFlo model which is specifically designed for those chemicals.
Pump Mounting Bracket: Heavy-duty mounting bracket included for secure installation. Isolates pump vibration and provides stable mounting platform.
Replacement Parts Available: Complete pump heads, diaphragms, valves, and motor assemblies are available for field servicing and maintenance. Remco's commitment to parts availability ensures long-term serviceability.
Optional Accessories: Pressure switches, flow controllers, tank strainers, hose assemblies, and spray tips are available to complete your spraying system.
Proper Sizing: Use appropriate hose diameter (3/4" minimum recommended) and avoid excessive hose lengths that create back pressure. Inlet Filtration: Install a tank strainer or inline filter to prevent debris from damaging pump valves and diaphragms. Pressure Relief: Install a pressure relief valve set 10-15 PSI above operating pressure to protect the system from over-pressurization. Regular Maintenance: Inspect and clean valves quarterly, replace diaphragms annually or as needed based on operating hours and chemical exposure. Proper Storage: Flush system with clean water after each use, especially when using aggressive chemicals or fertilizers.
