Abstract (en)
[origin: EP0864759A2] The pressure pump (1) has a lateral suction connection (2) equipped with an horizontally directed fitment piece (5) with defined connecting apertures. This fitment piece consists of a nipple with a metric thread. The cistern pump (3) is completely encapsulated and the electric motor (4) has a vertically arranged shaft, which is mechanically connected with the pressure pump part. The pressure pump is a multi-stage centrifugal pump, whose shaft is aligned with that of the electric motor. The pressure side of the pump is connected with a double-walled tube, which is positioned as cooling cover around the electric motor. The suction connection is connected with an extension piece for a suction filter. The pump with its under side is anchored to a stand plate (9), which has vibration dampers (10,11).
