HIGH-FLO

HIGH-FLO is a brand of diaphragm pumps used in agricultural, industrial, and commercial spraying and fluid-transfer systems. The line is known for on-demand electric sprayer pumps that combine a positive-displacement diaphragm design with a demand pressure switch, allowing the pump to start and stop automatically as flow is required. This operating principle reduces cycling and power draw compared with continuous-duty pumps, and it is well suited to sprayer systems where the operator controls flow at the nozzle or wand. The pumps are built with a GFPPL (glass-fiber reinforced polypropylene) housing and Viton elastomers, materials selected for resistance to a range of agricultural chemicals, cleaners, and mild industrial fluids. Available configurations differ primarily in the number of diaphragms—two, three, or four—which affects flow rate, pressure stability, and pulsing characteristics. The demand pressure switch is integrated into the pump body, simplifying plumbing and wiring in retrofit or new-build sprayer systems. Typical applications include agricultural sprayers, turf and landscape equipment, vehicle-mounted spray tanks, pressure washing and misting systems, and transfer of compatible chemicals in industrial settings. Because the wetted materials are GFPPL and Viton, the pumps are compatible with many common pesticides, herbicides, fertilizers, and cleaning solutions, though chemical compatibility should always be verified against the specific fluid and concentration. The pumps are self-priming in most configurations and can run dry for short periods without damage, which is useful in demand-controlled systems where the supply may be interrupted. Electrical configurations vary by model and are typically designed for low-voltage DC operation common in mobile and vehicle-mounted equipment. 3G Electric supplies HIGH-FLO on-demand electric sprayer pumps as part of its industrial equipment catalog. The available SKUs include models with two, three, and four diaphragms, all sharing the GFPPL housing and Viton seal construction. Each listing includes manufacturer part numbers, diaphragm count, housing material, and seal material so buyers can match the pump to the required flow and pressure. 3G Electric supports the line with global logistics, documentation, and quotation services for original equipment manufacturers, maintenance teams, and procurement groups. For technical selection, the key variables are the number of diaphragms, the demand pressure switch setting, the chemical compatibility of GFPPL and Viton with the fluid, and the electrical supply available on the equipment. Buyers should confirm the pump model against the sprayer manufacturer’s specification or the required flow rate at the target pressure. 3G Electric can provide spec sheets and part-number cross-references to help confirm fit. The brand’s focus on demand-controlled diaphragm pumps makes it relevant to any application where automatic pressure regulation and chemical resistance are required in a compact, electrically driven package.

Frequently asked questions

Common questions about HIGH-FLO from 3G Electric.

What is the difference between the HIGH-FLO on-demand electric sprayer pumps with two, three, and four diaphragms?

The diaphragm count is the primary differentiator among the HIGH-FLO on-demand electric sprayer pump models. A two-diaphragm pump (for example, manufacturer part number 5151086) produces a given flow and pressure with a certain amount of pulsation. A three-diaphragm model (5151087) and a four-diaphragm model (5151088) generally provide smoother output and can be specified for higher flow or more stable pressure in sprayer systems. All three share a GFPPL housing and Viton elastomers and include a demand pressure switch. Selection depends on the required flow rate, pressure stability, and the sprayer manufacturer’s specification.

What materials are used in HIGH-FLO on-demand electric sprayer pumps, and what chemicals are they compatible with?

HIGH-FLO on-demand electric sprayer pumps use a GFPPL (glass-fiber reinforced polypropylene) housing and Viton elastomers for the diaphragms and seals. GFPPL provides structural strength and resistance to many agricultural chemicals, while Viton is selected for compatibility with a range of oils, fuels, and aggressive fluids. These materials are commonly used with pesticides, herbicides, fertilizers, and mild cleaning solutions. Compatibility depends on the specific chemical, concentration, and temperature, so the fluid manufacturer’s compatibility chart should be consulted before use. 3G Electric can provide material specifications for review.

How does the demand pressure switch work on a HIGH-FLO electric sprayer pump?

The demand pressure switch on HIGH-FLO on-demand electric sprayer pumps monitors outlet pressure. When a spray valve or nozzle is opened, pressure drops and the switch starts the pump. When the valve closes, pressure rises to the switch set point and the pump stops. This on-demand operation reduces unnecessary running, limits heat buildup, and lowers power consumption compared with continuous-duty pumps. It also allows the pump to be mounted remotely from the spray control point. The switch set point is factory-configured for the pump model; buyers should confirm that the set point matches the system’s pressure requirements.

Can HIGH-FLO on-demand electric sprayer pumps run dry?

HIGH-FLO on-demand electric sprayer pumps are diaphragm-type positive-displacement pumps. In many configurations, they can run dry for short periods without immediate damage, which is useful during priming or when the supply tank runs empty. However, prolonged dry running can cause excessive wear to the diaphragms and valves. The demand pressure switch helps limit dry running by stopping the pump when no flow is required, but it is not a guarantee against dry-run damage. For systems where dry running is frequent, additional protection or operator procedures should be considered.

What information is needed to select the correct HIGH-FLO sprayer pump model?

To select a HIGH-FLO on-demand electric sprayer pump, the required flow rate at the target pressure, the electrical supply available (voltage and current type), the chemical being sprayed and its concentration, and the mounting and port configuration are needed. The diaphragm count (two, three, or four) affects flow and pressure stability. The manufacturer part numbers 5151086, 5151087, and 5151088 correspond to different diaphragm counts. 3G Electric can provide spec sheets and cross-reference existing pump part numbers to help confirm the correct model for the application.
