Delavan Cast Iron 8-Roller Pump
The Delavan 8900C series features an eight-roller design built from cast iron, delivering 24 GPM at up to 150 PSI with a rated speed of 1000 RPM. This configuration favors smooth liquid transfer and reliability in agricultural sprayers or industrial fluid transfer tasks where consistent pressure matters. The cast iron construction enhances durability in challenging environments, and the unit’s inherently simple rotor layout supports straightforward maintenance in the field. Applications include agitation, weed control mixtures, and various water-soluble chemical transfers where stability under load is essential.
HYPRO 7560C Cast Iron 8 Roller Pump
The HYPRO 7560C is a robust eight-roller pump designed for heavy-duty spraying. Cast iron construction provides wear resistance, while the eight-roller design supports smoother fluid transfer and high reliability in demanding spraying schedules. This pump is suitable for agricultural sprayers, pressure washing setups, and transfer operations requiring consistent performance at elevated pressures. When pairing with compatible engines or PTO drives, the 7560C delivers dependable flow up to about 22.5 GPM at high efficiency, with high-end models achieving 300 PSI at 1000 RPM. Maintenance considerations include seal wear and rotor inspection for long service life in outdoor environments.
7560C Cast Iron 8 Roller Pump (GMKYH)
This 8-roller model emphasizes durability with cast iron construction and broad compatibility. It delivers a maximum flow around 22.5 GPM and supports high-pressure operations up to 300 PSI, making it suitable for intensive agricultural spraying or industrial cleaning tasks. The design aims for reliable start-up and sustained operation under load, aided by robust rollers and a heavy-duty housing. For installers, the unit’s 3/4″ NPT ports align with common sprayer lines, enabling easy integration into standard systems.
7560C Cast Iron Housing 8 Roller Pump (Zgrao)
From Zgrao, this 7560C housing unit emphasizes rugged cast-iron construction with a 15/16″ solid stainless steel shaft. It delivers around 22.5 GPM with up to 300 PSI, and features a 3/4″ NPT port size for flexible installation. The design supports extended service life in harsh environments, including agricultural fields and industrial spray operations. The counterclockwise rotor orientation and the eight-roller configuration contribute to smooth fluid flow, reduced pulsation, and reliable field serviceability, which is advantageous for ongoing maintenance cycles in demanding spraying workflows.
Delavan 6900C 6 Roller Pump
The Delavan 6900C variant features a six-roller design with cast-iron construction and is optimized for agricultural spraying and water transfer. It presents a broad range of RPM options (540/1000) and GPM across different PSI targets, ensuring compatibility with varied sprayer configurations. The product offers comprehensive specifications covering shaft diameter, inlet/outlet, and overall dimensions, allowing precise matching with existing hoses and mounting platforms. This pump is a practical choice when space or budget considerations favor a lower-roller count with still solid performance.
Buying Guide: Key Purchase Considerations
When selecting a roller pump for sprayers, consider the following factors to ensure compatibility and long-term value:
- Flow rate and pressure: Match the required GPM and PSI to your sprayer’s nozzle pattern, tank size, and spray requirements. Higher GPM does not always mean better if your system cannot handle higher flow.
- Number of rollers: 6-roller designs tend to be more compact and economical, while 8-roller pumps generally offer smoother flow and higher durability for continuous use.
- Material and durability: Cast iron bodies are common and durable but heavier. Consider corrosion resistance if spraying with chemically aggressive liquids; alternative materials may be offered by some models.
- Inlet/outlet ports and NPT size: Ensure 3/4″ NPT or other port sizes align with your hoses, fittings, and adapters to avoid bulky modifications.
- Drive compatibility: Check PTO, belt, or engine drive compatibility and shaft dimensions to ensure proper mounting and alignment with your power source.
- Self-priming capability: Self-priming pumps reduce startup time and improve reliability when moving between tanks or elevations.
- Maintenance access: Look for modular rotors and accessible seals to simplify field servicing and extend pump life.
- Environmental and chemical compatibility: If spraying fertilizers or harsh chemicals, review seals and rotor materials for resistance to wear and chemical exposure.
- Warranty and support: Consider brands with established support channels and parts availability for ongoing maintenance and replacements.
- Installation footprint: Dimension and weight influence mounting options and vehicle or trailer integration.
Overall, the right roller pump balances flow, pressure, durability, and compatibility with your sprayer setup. The five models highlighted here provide a range of capabilities—from high-flow, high-pressure configurations to compact, versatile options—supporting diverse spraying tasks in agriculture and industrial settings.
