Oscillating piston vacuum pump is constructed from identical modules, each with piston drive and mounted on common rail, dependent upon customer demand

摘要

The pump is constructed from several identical modules, fastened to a common rail. The modules are connected parallel and/or behind each other, dependent upon customer demand. Each module has an oscillating piston drive. Intake and outlets (55,56) are located on the end faces of the modules, and these modules are fastened to the rails. This creates a common intake channel (57) and a common outlet channel (58), with an opening of the intake channel forming the pump intake, and an opening of the outlet channel forming the pump outlet.
