A hot melt adhesive metering pump assembly, and an integral reservoir tank fluidically connected thereto and the hot melt adhesive metering pump assembly comprises a plurality of rotary, gear-type metering pumps which are arranged in a compact, longitudinally spaced manner upon a drive gear manifold. All of the driven gears of pumps are respectively driven by manifold pump drive gears which are rotatably mounted upon a common motor-driven rotary drive shaft rotatably disposed within the drive gear manifold, and a first side wall member of a base portion of the reservoir tank is integrally connected to a side wall portion of the drive gear manifold, while a second side wall member of the base portion of the reservoir tank is provided with a plurality of hose connections to which hot melt adhesive delivery hoses are to be connected so as to respectively convey the precisely metered amounts of the hot melt adhesive material toward the applicator heads.

Hot melt adhesive metering pump assembly with integral reservoir tank

A new and improved remote, hot melt adhesive metering station (), for supplying predetermined or precisely metered volumes of hot melt adhesive material toward applicator head or dispensing nozzle structures, comprises a plurality of rotary, gear-type metering pumps () which are arranged in a compact, longitudinally spaced manner upon an axially elongated drive gear manifold () such that the rotational axes of the plurality of rotary, gear-type metering pumps () are disposed parallel and adjacent to one side of the axially elongated drive gear manifold (). Hot melt adhesive material is supplied from a remotely located adhesive supply unit (ASU), to the drive gear manifold (), by an inlet supply port hose connection (), and all of the pump driven gears () of the plurality of rotary, gear-type metering pumps () are respectively driven by manifold pump drive gears () which are all rotatably mounted upon a common, motor-driven drive shaft () rotatably disposed within the drive gear manifold (). The drive gear manifold () is also provided with a plurality of outlet port hose connections () to which hot melt adhesive delivery hoses are to be connected.
