Retrofittable pumping system for liquid/paste application

UK Flowtechnik (Nottingham, UK) has launched the trademarked VISCO.pump, a compact system designed specifically to enable the precise, automatic dosing of fluids and pastes.

UK Flowtechnik (Nottingham, UK) has launched the trademarked VISCO.pump, designed by Beinlich Pumpen GmbH (Gevelsberg, Germany) the renowned manufacturer of gear and radial piston pumps designed specifically to enable the precise dosing of fluids and pastes proportionate to the rotational speed. Its pumping principle enables precise dispensing of beads and dots as required, as part of an automated process. VISCO.pump is said to accurately dispense liquids and pastes with up to 60% filler content. The dosing quantity can be set to be absolutely linear, with dosing accuracy/ repeatability of ±1% or less. The company claims the pump’s linear volumetric efficiency and high predictability on delivery makes the pump almost “plug-and-go” — it is reportedly much easier to use than other pump designs and the cost of installing and commissioning it is comparatively low, and it can be retrofitted into existing systems, if required.

VISCO.pump applications include  dosing of filling compounds, coating of electronic components, protective coating of printed circuit boards, application of epoxy resin adhesives, bead dispensing, sealing, underfillings, dosing and metering and filling.

The geometries of the pump — the compensation of the inlet pressure, in particular — reduce considerably the installation space required. That and other adaptations of the rotor and stator geometries enabled Beinlich to make the VISCO.pump significantly smaller than previous systems. This makes the pump particularly well-suited for use in small dosing robots, says the company, because the centrifugal forces in fast, dynamic traverse paths cannot influence the pump. Moreover, the wall thickness of the rubber must be adapted to the counter-pressure so that the pump can function at optimal pulsation. The adapted geometry of the displacer reduces the necessary starting torque, whereby small, dynamic motors without transmissions can be assembled, thus reducing the weight and the installation length.
