FIMCO 5151087 Hi Flo Diaphragm Sprayer Pump
This 12-volt DC diaphragm pump delivers up to 2.4 GPM with a maximum 60 PSI level, designed for compatibility with common sprayers and 10-amp circuits. The unit uses Viton valves and a Santoprene diaphragm, offering strong chemical resistance and reliable performance for standard agricultural and landscape spraying tasks. Notable improvements include increased motor life, optimized chamber flow, and enhanced check valves, contributing to longer service life and steadier spray. It also includes a dual-warranty structure for consumer and commercial applications.
Hypro 6500C Roller Pump with Quick Coupler (Bundle)
This bundle includes two items: a Hypro 6500C roller pump and a 1321-0006 quick coupler. It supports a high flow of up to 22 GPM and handles pressures up to 300 PSI, with a maximum speed of 1200 RPM. The ports are 3/4″ NPT with a 5/8″ solid stainless steel shaft, and the design uses a CCW rotation suitable for many standard sprayer configurations. It’s a robust option for larger applications or agricultural spraying where rapid liquid transfer is essential.
HYPRO HYPRO 4101C 4-Roller Pump
Designed for demanding spraying tasks, the HYPRO 4101C offers up to 7.2 GPM and 150 PSI with a 2600 RPM rating. It uses a solid shaft and Viton seals, ensuring compatibility with fertilizers, agricultural chemicals, and industrial liquids. The cast iron housing and components provide rugged durability in tough environments, making it a strong candidate for heavy-duty fertilization and chemical transfer duties where long-term reliability matters.
PTO Valve Air Kit for Dump Trucks (Kozlira)
This complete PTO valve air control kit provides a full pneumatic solution for dump truck hydraulic systems. It includes the valve, a 10-meter air tube, a console tower, and installation accessories. The kit features a four-position PTO switch with auto-disengage and a safety light to enhance operator awareness. It emphasizes feathering control for smooth, precise descent and a self-locking middle position to prevent unintended movement, improving overall system safety and control during operation.
Buying Guide — Key Purchase Considerations
When selecting a PTO sprayer pump rebuild or control kit, consider compatibility with your current sprayer model, electrical requirements, and the chemical types you routinely handle. Look for:
- Flow and pressure requirements: Match GPM and PSI ratings to your spray pattern and coverage area. Higher flow suits larger landscapes, while moderate flow supports precision applications.
- Chemical compatibility: Viton seals and Santoprene diaphragms resist common fertilizers and agricultural chemicals, but confirm compatibility with any specialty products you use.
- Durability and materials: Cast iron housings and solid shafts contribute to longevity in challenging environments, especially with abrasive liquids.
- Power and wiring: Ensure 12V DC operation aligns with your battery capacity and fuse protection. Assess total amperage draw to prevent electrical overloads.
- Installation and compatibility: Quick couplers and standard NPT fittings simplify installation with existing lines and hoses.
- Warranty and service: Consumer or commercial warranties can provide peace of mind and support for maintenance or part replacement.
For selecting between a diaphragm pump, roller pump, or complete PTO valve kit, weigh the trade-offs between flow stability, chemical resistance, and maintenance requirements. Diaphragm pumps are robust for varied chemicals; roller pumps excel at high_flow applications; valve kits emphasize precise control and safety during operation. Your choice should align with spraying tasks, liquid types, and available electrical infrastructure.
