Abstract: A melter for preparing a molten medium, in particular for preparing a molten adhesive, has a melting tank that has a melting chamber for receiving and melting a medium to be melted. The melter has a heating device for heating the melting chamber. The melting chamber has an upper chamber section and a lower chamber section. The melting tank has a dispensing opening that can be fluidly connected to a delivery device for delivering the molten medium. The melting tank further has a drain opening. The dispensing opening and the drain opening open into the lower chamber section. The melter further has a closure body for closing the drain opening. In a closed position, the closure body closes the drain opening and an end section of the closure body projects into the lower chamber section.

Abstract: A delivery unit for dispensing adhesive having a housing, a melting apparatus arranged within the housing for melting the adhesive, a distributing device for dispensing molten adhesive in at least one line connectable to the distributing device, and a pump for conveying the molten adhesive through the distributing device, wherein the housing has a plurality of outer side faces, two of the outer side faces are of a flat configuration and arranged perpendicular to a support plane of the delivery unit on a base and substantially at a right angle to each other, and wherein the distributing device, in a region in which the line is connectable to a connector of the distributing device, has a boundary surface of a flat configuration. The two outer side faces are arranged at a distance apart with the boundary surface therebetween forming an obtuse angle with each of the two outer side faces.

Abstract: A piston pump and a method for determining a volume Veff of a liquid medium delivered to a consumer by a double acting, pneumatically driven piston pump, wherein the piston pump is subject to leakage when a constant pressure is acting on a drive of the piston pump and at least one double stroke of a piston pump from one dead center position thereof to the other dead center position thereof and back to the first dead center position is carried out includes: a. without the piston pump being able to deliver the medium to the consumer, a leakage time tL auf for one stroke of the piston pump from the bottom dead center position thereof to the top dead center position thereof is measured, b. without the piston pump being able to deliver the medium to the consumer, a leakage time tL ab for one stroke of the piston pump from the top dead center position thereof to the bottom dead center position thereof is measured, c. a quotient of a volume of the medium Vauf theoretically delivered by the piston pump without leakage and of the leakage time tL auf is determined for the stroke of the piston pump from the bottom dead center position to the top dead center position, d. a quotient of a volume Vab theoretically delivered by the piston pump without leakage and of the leakage time tL ab is determined for the stroke of the piston pump from the top dead center position to the bottom dead center position, e. the time tauf for the stroke of the piston pump from the bottom dead center position to the top dead center position and the time tab for the stroke of the piston pump from the top dead center position to the bottom dead center position is measured as the medium is delivered to the consumer, f. the effectively delivered volume Veff is multiplied by the number of double strokes in accordance with V eff = ( V auf - V auf t L   auf × t auf ) + ( V ab - V ab t L   ab × t ab ) .
