More Information
Summary:The invention relates to a motor pump unit (12) for a high-pressure cleaning device (10), wherein the cleaning fluid conveyed by the pump assembly (34) is used for cooling the motor (22), comprising a motor housing (32) surrounding the motor (22) and a cooling channel (42), which surrounds the motor (22) and through which the cleaning fluid can flow for heat removal. In order to provide such a motor pump unit in which the electrical safety is enhanced relative to a conventional motor pump unit, according to the invention the cooling channel (42) surrounds the motor housing (32), wherein the motor pump unit (12) comprises at least one heat-conducting spacer element (48) by means of which the cooling channel (42) is spaced relative to the motor housing (32). The invention further relates to a high-pressure cleaning device.
