Description
Pump head DG2A is a dual-channel pump head fitted with 6 rollers and constructed for flow rates up to 75 ml/min. Tubing with a wall thickness of 1 mm and an inner diameter of 1–3 mm can be installed in the head. The two-channel arrangement allows simultaneous handling of two fluid lines within a single compact unit. Available as one piece from manufacturer Landgraf HLL, the DG2A is intended for integration into matching pump systems used in laboratory environments. Each channel accepts tubing within the specified dimensional range, enabling flexible configuration for parallel transfer or comparative dosing tasks. The six-roller design provides reliable occlusion and steady conveyance across the stated flow range. Compact form factor simplifies mounting and exchange on compatible drives. By combining dual-channel capacity with clearly defined tubing limits and a maximum throughput of 75 ml/min, the DG2A supports efficient multi-line fluid handling in routine analytical and process applications where two independent streams are required.

Questions about Pump head DG2A, 2 channel, 6 rollers, up to 75 ml/min
What is this article?
Pump head DG2A, 2 channel, 6 rollers, up to 75 ml/min is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Shakers, rockers & rotators, inside Stirring, shaking & mixing, in Lab instruments.
A shaker, rocker or rotator moves a rack, a plate or a bottle so the contents keep moving without a stirrer bar. Orbital, reciprocating and rocking motions are different. The platform, the load and the speed range are the specification.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
