Specifications
Product Description
The Shurflo Pressure Pump 24V 2.1 l/min 80 PSI 8005-991-837 is a 3-chamber diaphragm pump specially designed to operate as a reverse osmosis booster and filtration systems at 24 V. Unlike the model without a pressure switch, it integrates an adjustable pressure switch 60–80 PSI (factory setting: cuts off at 80 PSI and resets at 60 ± 5 PSI), allowing on-demand operation without the need for external control. Its self-priming capability up to 7 ft (≈2.1 m) simplifies installation with a tank below, while the one-way check valve prevents backflow and maintains the water column in the line.
Main Features
- Nominal voltage 24 VDC with permanent magnet motor and thermal protection.
- Integrated pressure switch: cut-off at 80 PSI, start at 60 PSI (adjustable between 60–80 PSI).
- Nominal flow rate 2.1 l/min (0.55 GPM) open flow; stable performance at high pressure.
- Self-priming 7 ft and maximum inlet pressure 30 PSI.
- Ports 3/8"-18 NPT female compatible with standard fittings.
- Materials: Nylon (body), EPDM (valves), and Santoprene (diaphragm).
Advantages or Benefits
- Simple automation: the pressure switch manages ON/OFF according to line pressure.
- Pressure accuracy to maximize R.O. membrane performance and improve produced water quality.
- Flexible installation thanks to self-priming and 3/8" NPT ports.
- Reliability with integrated check valve and positive displacement design.
- Efficiency: low consumption (≈ 0.5–1.6 A depending on pressure), ideal for 24 V and off-grid systems.
Purpose or Applications
Booster for domestic/boat reverse osmosis, precision filtration, laboratories, vending, and any system requiring controlled pressurization with limited flow. Also useful as a booster pump in instrumentation circuits and small water processes.
