Specifications
Product Description
The Shurflo Pressure Pump 12V 6.8 l/min 50 PSI 8000-543-250 is a 3-chamber diaphragm pump designed for continuous operation in agricultural spraying and mobile applications. It is designed without a pressure switch to operate with line valves/nozzles, incorporating a 45 PSI internal bypass that stabilizes pressure and prevents overloads when flow is restricted. Its polypropylene construction with Viton valves and Santoprene diaphragm ensures chemical resistance and long service life.
Main Features
- Power supply: 12 VDC with permanent magnet motor and thermal protection.
- Nominal flow rate: 6.8 l/min open flow; stable operation with nozzles at 30–50 PSI.
- Pressure control: 45 PSI internal bypass (no pressure switch; max. bypass 60 PSI).
- Self-priming: up to 11 ft (≈3.3 m); max. inlet pressure 2.1 bar (30 PSI).
- Connections: 3/8"-18 NPT female for direct threading to fittings/nozzles.
- Materials in contact: PP (body), Viton (valves), Santoprene (diaphragm).
Advantages or Benefits
- Continuous and stable operation for spraying and phytosanitary treatment equipment.
- Greater reliability by operating without a pressure switch: fewer cycles, less water hammer, and fine control from the valves.
- Easy installation: 3/8" NPT ports, base with silentblocks, and compact size.
- Chemical resistance thanks to Viton/Santoprene; suitable for numerous agricultural products.
- Low maintenance with available 8000 series kits and spare parts.
Purpose or Applications
Ideal for agricultural spraying (fan/cone nozzles), backpack and cart sprayers, dust control on machinery, humidification, and portable 12 V equipment. Also suitable for technical cleaning and light transfers where moderate pressure and controlled flow are required.
