Solenoid Diaphragm Pumps

Field of application:
Designed for the exact dosing of liquid media in all industrial fields. The dosing control is performed process-bound for the most part.
R204.1/ C204.1
Electronically controlled dosing pumps which can be used for many applications. They are designed for industrial use and guarantee highest operational reliability.Extended  range for all magnetic diaphragm pumps by one 0.4 l pump. The new pump types are also fitted with a high quality Full PTFE diaphragm.
Performance range: 0,4 l/h and 35 l/h
pressures up to max.: 10 bar.
Capability characteristics:
Directly controllable  PROFIBUS-DP-Interface  High dosing accuracy  Long service life of diaphragms*  High qualitiy materials  Linear control characteristic  Low maintenance  Low operational costs  Leakage-free  Unlimitedly safe to run dry  Easy to operate  Low weight
* in comparison with previous commercially available drive diaphragms

sera solenoid diaphragm pumps R204.1 and C204.1
Self Ventilating Solenoid Diaphragm Pumps
RS204.1/ CS204.1
electronically controlled, selfventilating dosing pumps which can be used for many applications. They are designed for industrial use and guarantee highest operational reliability. They are used for the dosing of easily degassing media in combination with small liquid quantities.
Without an automatic venting valve, a failure of the pump often occurs as gases accumulate in the pump body and in the valves. The automatic venting valve is controlled using an automatic venting device via the pump electronics.
Performance range: 0,4 l/h and 35 l/h
pressures up to: max. 10 bar.
Capability characteristics:
Self ventilating  Directly controllable  PROFIBUS DP-Interface  High dosing accuracy  Long service life of diaphragms*  High qulaity materials  Linear control characteristic  Low maintenance  Low operational costs  Leakage-free  Unlimitedly safe to run dry  Easy to operate  Low weight
