The product notes do not include explicit GPM or PSI values beyond general capability, but the design aligns with standard 3/4″ NPT mounting and conventional sprayer systems.
7560C Cast Iron 8 Roller Pump Compatible With Hypro
Rugged build and flow potential: This entry emphasizes a rugged cast-iron construction paired with an 8-roller layout designed for stability under continuous operation. The description notes a wide operating window with a maximum pressure around 300 PSI and a flow range that can reach up to 22.5 GPM in some configurations, which is suitable for larger sprayers or tasks requiring higher throughput. The design also supports flexible installation, including counterclockwise rotation and three-quarter inch NPT connections for easy integration with existing sprayer systems.
Maintenance and versatility: The unit is described as adaptable to various drive schemes, including PTO or engine-driven setups. That flexibility helps managers tailor installation to different sprayer rigs, potentially reducing downtime during routine maintenance or component swaps. While exact performance figures depend on the installation, the configuration is well-regarded for industrial spraying tasks needing reliable prime and steady flow.
Hypro 6500C Roller Pump, Cast Iron (6500C)
Design and capacity: The Hypro 6500C is a six-roller cast-iron pump designed for agricultural and industrial spraying. With a flow profile around 22 GPM at higher speeds (1000 RPM) and a lower 9.7 GPM at 540 RPM, it provides flexibility for different spray pressures and coverage needs. The cast-iron construction supports durability in demanding environments, and 3/4″ NPT inlet/outlet ports match common sprayer interfaces, simplifying retrofits or upgrades on existing rigs.
Operational characteristics: This model emphasizes a balance between flow and pressure suitable for medium to large sprayers. The six-roller arrangement is known for smooth operation and reliable prime, particularly when paired with standard engine or PTO drives. Users typically select this pump when they need solid throughput without stepping up to the higher-roller, higher-cost variants.
Delavan Cast Iron 8-Roller Pump – 24 GPM
High-flow capability and Robustness: The Delavan 8-roller model is specified to deliver 24 GPM at 150 PSI, with a 1000 RPM operating speed. Cast iron construction supports durability in challenging spraying applications, including agricultural and industrial tasks where larger volumes are required. The 8-roller arrangement promotes stable flow and consistent discharge across a range of duty cycles, making it a popular choice for high-demand sprayers.
Key features: The design focuses on a straightforward, field-serviceable format with standard mounting points and 3/4″ NPT connections. This aligns with common sprayer configurations, enabling easier maintenance and part compatibility across different brands and rigs. The product line is often chosen for its proven reliability in continuous spraying operations where uptime matters.
Delavan 6900C 6 Roller Pump
Comprehensive specifications and field practicality: The Delavan 6900C 6-roller unit is described with extensive data, including rotation direction, RPM options, intake and discharge fittings, and various GPM metrics across different PSI points. Features emphasize a cast-iron housing, field serviceability, and inclusion of premium components like Viton lip seals and heavy-duty sealed bearings. The design caters to agricultural spraying and water transfer tasks, offering versatility across diverse conditions.
Performance profile: This pump is positioned as a reliable mid-range option that balances flow (up to around 19.6 GPM at zero PSI) with adequate pressure (up to 150 PSI).

Buying Guide: Key Considerations For Roller Pumps
- Flow rate and pressure: Match GPM and max PSI to your sprayer’s nozzle arrangement, tank size, and desired coverage. Higher roller counts often yield smoother operation at elevated flows, but may increase cost.
- Construction material: Cast iron offers durability and wear resistance in tough environments, but consider weight and corrosion risk in aggressive chemicals. Aluminum or composite components may be lighter but less robust for some tasks.
- Connection and compatibility: Check inlet/outlet sizes (commonly 3/4″ NPT) and shaft options to ensure compatibility with your engine, PTO, or belt drive. Confirm rotation direction (CW/CCW) for proper integration with your system.
- Maintenance and parts availability: Field serviceability, seal types (e.g., Viton), bearings, and availability of replacement rollers influence downtime and lifecycle costs.
- Chemical compatibility: Ensure materials resist your typical spraying fluids (water, fertilizer solutions, mild chemicals, etc.) to prevent premature wear or swelling.
- Installation footprint: Evaluate mounting space, vehicle or trailer configuration, and alignment with hoses and fittings to minimize routing complexity.
- Durability vs. cost: Higher-capacity, multi-roller pumps offer performance benefits but may incur higher upfront costs—balance with expected usage, maintenance, and uptime requirements.
- System integration: Consider whether the pump supports your existing drive train (engine, PTO, or electrical) and if it can be easily swapped without major plumbing changes.
In selecting a roller pump for sprayers, the ideal choice depends on the spraying task scale, chemical compatibility, and maintenance expectations. The listed options represent a spectrum from rugged, high-durability casts to flexible, broadly compatible units designed for various rig configurations. Always verify exact GPM/PSI figures from the supplier or technical data sheets for precise matching to your sprayer system.
