VoluBrane Pump 97643/97643 PAS
The VoluBrane Pump is suitable for volumetric dispensing of drops of anaerobics, cyanoacrylates, UV acrylics, acrylics
and activators up to 15,000mPas viscosity.
The VoluBrane Pump is self priming up to a viscosity of 500mPas. It is designed for integration into automated work
stations and robotic applications. A precise amount of product can be set and high repetition accuracy is ensured.
The maximum dispensing volume is 0.4 ml. The minimum dispensing volume is 0.004ml.
The volumetric VoluBrane Pump system comprises an air operated volumetric diaphragm pump, one electromagnetic
dispense and one fi ll valve, electronic stroke adjustment, an electronic control system and a 4 pin I/O. Dispensing
volume is adjusted on the thumb wheel and via display indication. It is monitored by electronic measurement of the
diaphragm stroke.
During priming, the fi ll valve is opened, the dispensing valve is closed. The product chamber is fi lled by suction
and, if required, also by the supply pressure of the material. Dispensing volume is mechanically adjustable.
During the dispensing cycle, the fi ll valve is closed while the outlet valve is open. Dispensing is controlled by a
pneumatic cylinder and the thumb wheel stroke adjustment.

Eccentric Rotor Pumps 97660/63/65/69
The Eccentric Rotor Pump is ideally suited for volumetric dispensing of materials ranging from anaerobic adhesives
and sealants to very pasty silicones.
The direction of fl ow is reversible and the dispensed amount proportional to speed of rotation, i.e. the system allows
for continuously variable adjustment of the dispensing rate via motor speed adjustment. The drive shaft is sealed by
two double acting sealing rings made of UHMW-PE and PTFE; it is fi tted with a barrier liquid connection.
Eccentric Rotor Pumps are positive displacement pumps providing volumetric dispensing and a nearly pulsation free
fl ow of material.
Volume fl ow depends on the size of the pump and the number of revolutions. The pumps can be driven by either a
digital AC servo drive or a DC drive. Pump and drive are fi xed together with a mounting clamp for fast assembly and
disassembly. As a rule, the pumps are operated with a shut-off valve at the product outlet as self-sealing capability will
degrade over time.
