Single-point level switch operating on Archimedes' principle — a non-floating polypropylene displacer suspended from a billet-aluminium head changes weight as it submerges, actuating a 20 A S.P.D.T. micro-switch (rated to 500 VAC) through a magnetic isolator. No metal parts in contact with liquid, full IP67 housing. -
Top entry two-position level regulator on a single suspended cord — two solid twist-lock displacers set the high and low switching points, from a 115 mm minimum to a 20 m maximum level differential. 20 A S.P.D.T. switch rated to 500 VAC (2 HP UL motor rating at 250 VAC) in a heavy-duty all-metal weatherproof housing. -
Four pressure switches in one. The E30 MK2 digital pressure switch can be configured to operate as a loss-of-prime switch, pressure guard for high/low protection, single-point snap-action switch, or dual-pump controller — 16 unique functions across 4 operating modes. -
Tough, highly-sensitive paddle switch for both hot and cold liquids. Magnetic repulsion drive (no seals, diaphragms or bellows) gives a high-pressure switch with no points of potential failure. Polypropylene or 316 stainless process connection; 3/4" or 1" BSP/NPT. -
A paddle flow switch with built-in digital timers that override the normally-off state of the switch and let a pump start in spite of an initial lack of flow. Includes an adjustable run-on timer that lets the pump ignore minor flow interruptions while still being fully protected against running dry. -
From a simple start-up timer to a full set of advanced flow- & time-based functions, the F29 MK3 is simply the most powerful and versatile flow switch available. -
The ultimate in versatile and flexible pump control — simple to use and very powerful. Monitors system pressure and flow to ensure complete pump protection, with five operating modes for single or dual pump systems. -
Built tough for the most arduous industrial and mining applications. Rugged but highly-sensitive paddle switch with a billet-aluminium housing and a one-piece 316 stainless steel process connection. 400 bar pressure rating, manual override built into all models. -
Designed for both fresh-water and effluent irrigation systems. Learns the operating pressure each time the system is started, then applies its own under- and over-pressure set points for highly targeted leak and over-pressure detection. Suits fixed pods or travelling irrigators. -
Compact 75 mm three-wire float switch for highly accurate and repeatable single point level sensing and control. Polypropylene float cell, hermetically sealed, with CPE rubber cable and no mercury or lead. Ideal for water, sea water, most acid and alkali solutions and effluent or sewage: the teardrop float has no shoulders or edges for solids to build on. -
Compact vertically-oriented probe-style float switch — 25 mm diameter outer body fits down a 25.4 mm pipe or borehole. Vented UPVC housing with internal polypropylene float. ±1 mm switching repeatability; ideal as an alternative to conductivity probes in submersible borehole pumps. -
Diesel- and oil-resistant variant of the K Series — same compact 75 mm tilt-action float, but with orange polyurethane cable made for single point level control in oils. NOT suitable for water or sewage applications. -
Side-entry float-arm level switch for tank and chemical-tank level control. Polypropylene or 316 stainless construction with a polypropylene float, 1" BSP / NPT process connection. 5–500 V AC, 15 A S.P.D.T. micro-switch (L-H) or low-voltage gold-contact micro-switch (L-L), both with a built-in manual override. -
Industrial / mining-grade side-entry float level switch — same proven action as the L Series but in a billet-aluminium housing with a 316 stainless steel process connection. Polypropylene float and arm; 5–500 V AC, 15 A S.P.D.T. micro-switch (LM-H) with built-in manual override, or low-voltage gold-contact micro-switch (LM-L). -
Super-sensitive version of the popular P20 inline flow switch — detects flows under 350 mL/hour. Pure-mechanical, magnetically-actuated, with no metal parts in contact with the liquid; ideal for monitoring chemical metering pumps, water treatment, cooling towers, and other low-flow industrial processes. -
Simple, reliable inline flow switch for liquids or gases in tubes and small-diameter pipes. Detects continuous or pulsed flows, with no metal parts in contact with the liquid — ideal for sea water, ground water, acids and chemical solutions. -
Rugged all-position flow switch for liquids in 15 mm to 25 mm (1/2" to 1") diameter pipes — up to 100 L/min. Detects continuous or pulsed flows; no metal parts in contact with the liquid. The P25-S model includes a heavy-duty mechanical switch + manual override for direct control of pump motors (motor load 8.3 A at 250 VAC, UL 2 HP). -
Larger, beefier sibling of the K Series — heavy duty polypropylene float fully overmoulded around a high quality three core cable. Heavy duty S.P.D.T. microswitch rated 21 A at 250 V AC, able to directly control small pump motors. Sealed, tamper-proof, no metal parts in contact with the liquid and highly chemical-resistant. -
Uses a flexible stainless wire sensor rather than a paddle to detect flow. Suits open discharge applications and pipes from 50 mm (2") upwards. Ideal where solids or semi-solids are present — sewage pumping, slurry, mining, and high-velocity normal pumping where paddles foul or fatigue. -
Mining/industrial-grade trailing-wire switch in a billet-aluminium housing with 1" 316 stainless steel process connection, for harsh mining applications. Suits open discharge applications and pipes from 50 mm (2") upwards. Tolerates high pressure, abrasive slurries, sewage, fibres, and high flow velocities. Built-in manual override. -
Magnetically actuated piston switch with a solid machined 316 stainless-steel body — 200 bar pressure rating, handles liquids up to 90 °C. Ideal for hot/cold water pressure boosting, gravity hot-water systems, safety showers and other high-reliability applications.
