Hypro Silver Series 7700N Roller Pump

Hypro Silver Series 7700N Roller Pump, 7-Roller, 13gpm @ 540Rpm, 3/4" inlet & outlet, 15/16" Shaft

The Hypro 7700N Roller Pump is a rugged, chemical‑resistant, 7‑roller positive‑displacement pump engineered for agricultural, industrial spraying, and transfer applications. Built to deliver consistent flow and pressure with low starting torque, it handles herbicides, fertilizers, emulsions, solvents, and more. With its durable Ni‑Resist housing and 15/16" solid shaft, the 7700N ensures long service life, even under demanding conditions.

✅ Key Features & Specifications

• Pump type: Roller‑pump, 7 roller assembly
• Inlet/Outlet port size: ¾" NPT
• Shaft: 15/16" solid stainless‑steel shaft
• Flow capacity: Up to 22.1 gallons per minute (GPM) / 83.7 liters per minute (LPM) at 800 RPM; roughly 14.2 GPM at 540 RPM
• Pressure rating: Up to 200 PSI (13.8 bar) intermittent; 100 PSI continuous recommended for extended duty
• Max fluid temperature: 140 °F (60 °C)
• Roller seals / rollers: Uses Super Rollers (poly/Teflon) for improved chemical resistance and longevity; standard Viton shaft seals for chemical compatibility and sealing integrity.
• Housing / Rotor materials: Ni‑Resist body (as “N” variant) — offers superior corrosion resistance compared to plain cast iron, better for aggressive chemicals or fertilizers.
• Weight: Approx. 14 lb (≈6.36 kg) for easy handling and installation.
• Rotation direction: Standard is ounter-clockwise (when viewing the shaft end), but clockwise versions or reversed‐rotation models are available.

🔧 Best Uses & Why It’s a Great Choice

• Agricultural spraying: Ideal for herbicides, pesticides, liquid fertilizers, and other chemicals — rollers and Viton seals resist chemical wear and give long life.
• Sprayer/chemical transfer: Its positive-displacement roller design ensures consistent flow regardless of pressure, making it reliable for both tank-fill and high-pressure spray systems.
• Durability & low maintenance: The Ni‑Resist or “Silver Series” housing and stainless shaft resist corrosion. The 7‑roller design provides smooth, continuous delivery with low starting torque — easier on drive motors or PTOs.
• Flexibility: Works on 540 rpm PTO shafts, electric motors, or gas engines; suitable for both small utility rigs and larger sprayer setups.
