1. A hydraulic unit configured for open-loop and closed-loop control of brake pressure in a brake circuit of an electronically slip-controllable braking system of a motor vehicle, comprising:
a pump housing equipped with an actuatable brake pressure generator;
a motor configured to drive the brake pressure generator; and
an electronic control device configured to electrically control the motor, wherein:
the motor and the control device are disposed on opposite sides of the pump housing from one another;
a shaft bore is formed on the pump housing, which shaft bore extends from a first side of the pump housing on which the motor is disposed to a second side of the pump housing to which the electronic control device is attached;
a motor shaft configured to be rotationally driven by the motor to form a rotational movement, is rotatably arranged in the interior of the shaft bore;
a sealing apparatus is configured to seal the shaft bore with respect to an interior of the electronic control device; and
the sealing apparatus comprises an insertion seal which is disposed in a seal socket of the pump housing and to which a mechanical preloading force is applied by a mechanical preloading apparatus to anchor the electronic control device to the pump housing.
