Lefoo, operating in various companies around the world, develops solutions for working in hydraulic systems, using water pumps and the entire system involved.
As a result, we have developed an extremely reliable line for pumping applications and automatic control of water pressure in hydraulic systems, with robust products and with a wide range of options for the specific needs of each customer and application.
Among this line are:
The LF55 pressure switch series is used with cooling fluids, air and water (up to 120 ° C). Its activation by MICRO SWITCH guarantees a reliable electrical switching. The mounting bracket provided is standard. SPDT electrical contacts (double contact). Other thread options are also available on request.
Pressosoato LF55 is widely used in fire systems, as an option of extreme quality to the pressure switches normally used, offering an incomparable cost-benefit ratio, supported by a credibility won by customers all over the world.
The LF55 pressure switch is also the ideal choice in water pumping systems, such as water tanks, reservoirs, etc.
We work with machine manufacturers, component distributors and companies responsible for the installation and maintenance of fire systems, in the development of components on demand, in addition to differentiated commercial conditions.
The LF20 pressure switch is specifically designed to support extended service applications. This switch is factory-set, but capable of being adjusted in the field. It has different diaphragms for compatibility with a wide variety of fluids and various terminations, including a Metri-Pack connector that forms a tight seal when connected. Prominent benefits of design include durable construction, compact size and improved setpoint integrity. It can be widely used for swimming pools and spas, anti-skid systems, water pump systems and dental air compressors, heavy construction, off-road equipment and other pressure control systems.
The T2000 pressure transmitter uses a ceramic pressure sensor that is temperature compensated and laser cut for accurate span and offset calibration. The typical advantage is its compact size, which facilitates installation in places with little space. Some typical applications of this pressure sensor are: Process and automation control, compressors and pumps, engine controls, Off-road vehicles, among others.
