| PRODUCT PERFORMANCE INFORMATION
|
The piston (5) is moved by the
electromagnetic field generated by the single wave diode rectified current
flowing through the coil (4).
Each current pulse moves the piston
against the pressure spring (3).
This movement by reducing the
volume in the suction chamber, opens the valve (6) set in the piston to
let the liquid run into the pressure side.
When the current pulse
ceases, the pressure spring pushes back the piston toward the pressure
side. The increase of pressure closes the piston valve and the liquid
flows through the valve (7) set in the pressure connection (8) and into
the pressure pipe.
This movement creates a low pressure in the
suction chamber which opens the valve (2) set in the suction connection
(1).
The liquid is sucked into the pump and the cycle starts again,
50 times per second (at 50 Hz).

The piston size and the length of
its displacement defines the flow rate. The pressure limits itself
automatically. The pump will run without damage when the liquid flow is
stopped momentarily, The pump works not only tied to the standard voltage
and frequency but can be controlled by a frequency regulation or a pulse
control unit.
