Features
Long life expectancy
The simple mechanism and the very few construction parts guarantee a long and reliable period of operation.
Low noise level
The soundproof casing and the muffler integrated in the tank base reduce operating noise. The Secoh diaphragm pumps are extremely quiet, as shown by the decibel values.
High degree of efficiency
Operation is based upon the principle of electromagnetic oscillation, which eliminates the need for any sliding parts, thereby minimising power consumption and providing a high degree of efficiency.
Completely oil-free
The completely oil-free operation guarantees a dry and unadulterated air flow.
Compact and light construction form
Motor and pump parts are combined in one single construction.
Low vibration
The pump casing is separated from the outer casing by vibration-isolating rubber
Very little pulsation
Thanks to the specially formed pump chambers and the muffler integrated in the tank base, the exhaust air flow is practically pulsation-free.
Rainproof
The SLL and EL series are rainproof and therefore eliminating the need for special housing and can be placed f. e. on a house wall.
Applications
The following examples demonstrate some possible fields of application.
- Domestic sewage plants
- Filter systems
- Koi and garden ponds
- Aeration of chemical and biological bath
- Scent systems and odour neutralisation
- Tank pressuration
- Airbeds and decubitus mattresses
- Underwater massages and whirlpools
- Compression therapy
- Aqua-Air-Lights and design pillars
Operating principle
The activated electromagnets put the magnet holder into a linear movement. The magnet holder, which moves back and forth between the electromagnet at the same frequency as that of the power supply, sets a diaphragm going on both sides, which then changes the valve box volume. By discharging via the valves, both vacuum and pressure can be realized.
The operating principle of an electromagnetic oscillation is well known for its excellent efficiency! The electrical energy is not used up by mechanical friction in crank assemblies, sliding parts or bearings, but is directly utilized for pump movement via the membranes. Lubricants are not necessary and are not to be found either in the linear drive or in the pump chamber. This means no wearing parts and therefore long lifetime, oil-free operation and absolute low power consumption.
