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.
Long life expectancy
The simple machanism 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.
