And what’s more, they are available on next day delivery so you can compensate for your forgetfulness as soon as possible. Kelco is a specialist manufacturer of corrosion resistant flow switches, level switches, and float switches, the majority of which have no metal parts in contact with process fluids. This feature allows them to be used reliably in aggressive liquids such as acids and alkalis, sea water and saline ground water. A mother was quoted today: “Give me superbly-engineered Australian hardware over chocolates and flowers any day of the week.”

| |  | The E10 loss of prime pressure switch is a solid-state digital pressure switch specifically for the control and protection of domestic and industrial pressure pumps and air compressors. Pressure switches normally have two set points, a low pressure cut in point and a high pressure cut out point.
A pump under the control of such a switch operates between the two set points. If pressure is lost due to the pump running dry, or due to a burst pipe, the pump will continue to run simply because the pressure switch remains on. In such a situation the pump will invariably sustain substantial damage due to being run dry.
| |
| | The E10 pressure switch addresses this problem by providing a third adjustable switch point that can be set below the normal operating range to turn the pump off and prevent it being damaged if it runs dry. | |
| | | The E10 Loss of Prime Pressure Switch features: | - Three digitally adjustable set points
- Suitable for sea water use
- Simple plug in installation
- Loss of pressure warning light
- Weatherproof to IP67
- 10 Bar (150psi) Rated
| - Four quadrant digital fine tuning
- Control motors to 3.75kw 5hp
- Automatic override on startup
- Indicator lights for all functions
- 10 Bar (150psi) Rated

| |  | Kelco manufactures flow switches that are ideal for use in pool pump and heater protection. Designed originally for rigorous applications in the harsh and aggressive ground water of the great Australian deserts and in heavy industrial water treatment, the Kelco paddle flow switches were quickly seized on by pool heater manufacturers because of their unique non-metal construction and total resistance to pool chemicals.
Used in bulk sodium hypochlorite handling systems in municipal and commercial pools, the Kelco flow switches soon found application in all facets of the pool industry.

| |  | The L26 series heavy duty level switches provide a highly reliable accurate and low cost solution to tank level control. Offering polypropylene or stainless steel and polypropylene construction, the L26 level switches are built tough, from their high impact weatherproof casing to their high compliance micro switches.
These level switches are intended to give long reliable duty under the most arduous conditions. The L26 level switch incorporates our unique seal less magnetic dampening system that both couples the internal switch mechanism to the float arm and ensures a reliable switching action even where surface agitation is present.
| | |
| | | Applications include: | - Low level protection for pumps
- Chemical tank level monitoring
- Safety monitoring in chemical tanks
| - Tank liquid level control
- Level control in water treatment
