UK Flowtechnik has launched a new small-scale progressive cavity pump designed specifically to enable the precise dosing of fluids and pastes proportionate to the rotational speed.
The VISCO.pump, made by Beinlich Pumps, can be used for dispensing polyurethane (PU) and can accurately dispense liquids and pastes with up to 60% filler content. The dosing quantity can be set to be absolutely linear, with a dosing accuracy and repeatability of ± 1 per cent or less.
The new technology is based on the volumetric principle of an endless or infinite piston where the rotor and stator components form a sealed metering chamber. The eccentric movement of the rotor allows for a low-shear motion of the medium from one chamber to the next chamber without damage to the media.
