Controllable Piston Diaphragm Pumps
are leak-free oscillating displacement pumps designed for the dosing of volumes up to 1500 l/h and up to maximum 50 bar - depending on flow capacity.
They are an ideal combination of the high supply pressure of a piston pump and the perfect leak-proof diaphragm pump.
Field of application:
Flow free mediums with:
Performance characteristics:
C409.2...KM
A suitable material is available for each dosing medium!
Appropriate materials are selected for valves, ball valves, valve seals and diaphragms.
The electronics make possible: proportional dosing via analogue signals 0/4 ... 20 mA or contact signal with the option of impulse partitioning or impulse multiplication.
An integrated LCD display and four LEDs give information about the actual status in operational mode, when empty,when diaphragm rupture occurs and when there are multiple faults.
A connection for a relief valve and a „pump empty“ display with beginning and end contact is standard equipment. As an option the dosing pump can be constructed with a diaphragm rupture signal.
Drive motor with single-phase alternating current.
