HYPRO 7560C Cast Iron 8 Roller Pump
The HYPRO 7560C is a rugged, eight-roller pump designed for heavy-duty agricultural and industrial spraying. Its cast iron body enhances durability in challenging environments, while the 8-roller configuration supports smooth, high-volume flow. Compatible with standard 3/4″ NPT connections, this unit can be driven by gasoline engines or PTO belts, offering flexible installation options. The 300 PSI maximum pressure helps maintain spraying precision under demanding conditions, and the self-priming capability minimizes downtime during setup. Users seeking long service life and reliable priming will benefit from the design principles of this model.
7560C Cast Iron 8 Roller Pump (Zgrao)
This 7560C variant from Zgrao emphasizes rugged cast-iron construction with a robust 15/16″ solid stainless steel shaft for extended service life. With a flow capacity around 12 GPM at 540 RPM and up to 22.5 GPM at higher speeds, it delivers strong performance for spraying and liquid transfer. The pump supports up to 300 PSI, ensuring precise and consistent spray patterns. Its counterclockwise rotation and 3/4″ NPT ports enable flexible installation, and compatibility with PTO or fuel engines adds versatility for field use.
Hypro 6500C Roller Pump, Cast Iron
The Hypro 6500C offers a six-roller, cast-iron design that delivers reliable performance across agricultural and industrial tasks. While a bit smaller than the 8-roller models, it remains a workhorse for mid-range spraying and transfer applications. Its 9.7 GPM at 540 RPM and wider torque tolerance support steady operation under real-world conditions. The unit’s durable construction and straightforward maintenance make it a practical choice for budget-conscious buyers requiring durability without excessive size.
Delavan Cast Iron 8-Roller Pump – 24 GPM
The Delavan 8900C is a classic 8-roller pump capable of delivering up to 24 GPM at 150 PSI. Built with cast-iron components, it is well-suited for heavy-duty field spraying and liquid transfer tasks. The generous flow rate supports rapid spraying on larger plots or for high-volume applications, while the 1000 RPM operating range helps maintain consistent performance. This model emphasizes durability, serviceability, and compatibility with standard hose and nozzle setups common in agricultural spray operations.
Delavan 6900C 6 Roller Pump
The 6900C 6-roller pump from Delavan focuses on broad compatibility and practical performance. With up to 19.6 GPM at 0 PSI and 9.7 GPM at 20 PSI, it covers both high-flow transfer and consistent spray output. The CCW rotation, cast-iron housing, and a detailed spec sheet indicate a design intended for rugged field use and long service life. The model lists an extensive feature set including Viton lip seals and sealed bearings, making maintenance and field service straightforward for commercial operations.
Generic 7560C Cast Iron 8-Roller Pump
The Generic 7560C Cast Iron 8-Roller Pump emphasizes broad system compatibility and robust construction. It features 3/4″ NPT ports and a maximum flow of 22.5 GPM with pressure up to 100 PSI, making it a versatile option for agricultural and industrial spraying setups. The self-priming capability supports efficient startup, while the eight-roller design aims to reduce pulsation and provide steadier flow for demanding tasks. Given its compatibility with gas engines, PTOs, or belt drives, this model suits a wide range of configurations.
Buying Guide: Key Purchase Considerations
- Flow rate and pressure: Match GPM and PSI ratings to your sprayer’s needs. Higher GPM helps cover larger areas quickly, but ensure your pump can operate within your system’s pressure range.
- Construction materials: Cast iron housings provide durability and corrosion resistance for agricultural use, while some models consolidate lightweight options for portable setups.
- Drive compatibility: Consider engine type (gas, PTO, belt-driven) and shaft size (for example, 15/16″ shaft) to ensure proper mounting and drive coupling.
- Self-priming capability: Essential for reducing startup time and air lock issues in field spraying and liquid transfer tasks.
- Maintenance and serviceability: Field-serviceable components, seals (Viton or similar), and ease of rotor/roller replacement reduce downtime and operation costs.
- Chemical compatibility: If spraying fertilizers or chemicals, verify wetted materials and seals are compatible with your liquids to prevent degradation.
- Size and mounting: Check available space and mounting patterns to ensure the chosen model fits your sprayer chassis or transport frame.
- Noise and vibration: Some eight-roller configurations provide smoother operation; consider mounting hardware and vibration dampening for quieter operation in the field.
- Warranty and support: Look for manufacturers offering solid warranty coverage and readily available parts to minimize long-term ownership costs.
When selecting a roller pump for sprayers, buyers should assess not only the peak specifications but real-world operating conditions, including fluid types, temperatures, and the required spray pattern. The models listed above span a range of capacities, from compact, mid-range units to high-volume, heavy-duty pumps, enabling informed comparisons for various agricultural and industrial spraying scenarios.
