The mechanics
Highest protection against chemical attacks, dust and spray water by
means of glass-fibre reinforced plastic. Sturdy, impact-proof, light and
enclosure rating IP 65 according to DIN 40050 and IEC 529.
Conventional pump drives consist of an electric motor with gears and
many moving parts.
The ProMinent solenoid drive has only one moving part, the armature!
This is a low-maintenance short-stroke solenoid with a new type of
noise suppression and a maximum stroke length of 1.25 mm.
The stroke length adjusting mechanism is connected directly to the
solenoid. Thus a most accurate stroke length adjustment is possible
without locking and self- adjustment.
A DEVELOPAN
fabric-reinforced high-quality EPDM with a vulcanised steel core and
PTFE Teflon coating on the media-contacted side.
Liquid ends for gamma pumps are available in four material versions
- polypropylene (PP)
- acrylic (NP)
- PTFE (TT)
- stainless steel 1.4571 (SS)
Additionally material versions PP and NP have a combined bleed valve
with fine adjustment.
Especially for highly viscous materials, liquid ends from the HV series
are available in
- polypropylene (PP4)
with extended flow cross section and larger, springloaded single ball
valves.
Gamma metering pumps are available for 230 and 115 V mains
voltages. Wide voltage ranges are accepted: from 207 to 254 V in the
upper and from 108 to 135 V in the lower range: for mains frequencies
from 50 to 60 Hz.
The electronic control system is continuously self-monitoring. In the
event of a system error in the microprocessor, the pump is switched off
and an alarm is issued.
Lighting
The optional illumination of the LCD display (4) guarantees that the
display can be easily read even in bad light conditions.
