Specifications
Product Description
The Shurflo Pressure Pump 12V 4 l/min 100 PSI 8000-441-138 is a 3-chamber diaphragm pump designed to provide high pressure and fine flow control in professional and mobile applications. With a pressure switch calibrated to 100 PSI (±5 PSI) and a self-priming design up to 3.7 m, it ensures on-demand, stable, and reliable supply even with misting nozzles or spray valves. Its permanent magnet motor with thermal protection, along with high-quality wetted materials (polypropylene, Santoprene diaphragm, and EPDM valves), provides durability and chemical resistance for demanding spraying, dust control, or technical cleaning tasks.
Main Features
- Controlled high pressure: pressure switch cut-off at 100 PSI ±5 PSI for fine mist and precision spraying.
- High self-priming: capable of priming up to 3.7 m (12 ft) with a lower tank.
- Stable flow: 4.0 l/min open flow and 2.1 l/min at 100 PSI, ideal for micronozzle misting.
- Robust construction: polypropylene body, Santoprene diaphragm, and EPDM valves for long service life.
- Continuous operation: continuous duty cycle (dependent on ambient temperature and ventilation).
- Standard connections: 1/2"-14 parallel male thread (NPSM) compatible with Shurflo swivel fittings.
Advantages or Benefits
- Precision and uniformity in the spray pattern thanks to constant pressure, improving the effectiveness of treatments and the use of water/product.
- Easy installation in portable equipment or vehicles: compact size, 1/2" connections, and base with silent blocks.
- Field reliability: motor thermal protection and positive displacement design with integrated check valve.
- Chemical resistance of EPDM/Santoprene for many cleaning products and agricultural uses (check fluid compatibility before use).
- Cost-effective maintenance thanks to the availability of filters, fittings, accumulators, and service kits from the 8000 series.
Purpose or Applications
Recommended for fine mist in humidification or temperature control systems, precision spraying in agriculture and gardening, dust control in street cleaning machinery, portable technical cleaning equipment, and off-grid applications where high pressure with controlled flow is required. It can also be used on board boats or in caravans when high pressure is needed for specific uses.
