For consistent, optimal system pressure and high-precision power support

The compact CP14 power steering pump supplies exactly the right amount of oil that is needed for operating hydraulic steering systems in passenger cars and light commercial vehicles.

Robust Design

Proven design ensures reliable supply to the steering system

High power density

with low weight

Flexibility

Modular assembly system

Our wide-ranging production program includes various pump designs and model series. We would also be happy to customize our solutions optimally to your individual wishes and requirements. Evamo's highly flexible modular assembly system makes most anything possible.

Because of our flexible construction method, we can implement customer-specific requirements in the production of the CP14 power steering pump. This gives us the option of installing customer-specific drive components or brackets in order to adapt the pump to the assembly space.

Individual product request
The innovative product design of the CP14 passenger car power steering pump has integrated volume control for energy savings in passenger vehicles.

Function

Light weight with integrated volume control

The CP14 power steering pump is powered via a motor belt drive. The hub or belt pulley is pressed onto the shaft. Mounting the pump to the engine bracket is done either directly or via a pump bracket.

The CP14 consists of a housing with a pressed-in intake port and an integrated volume flow control, valve screw with a pressure connection thread, cover, front plate, shaft and rotor set. The rotor set is comprised of a rotor, ten radially-guided blades as well as the cam ring with two symmetrically arranged suction and pressure zones.

The fixed geometric delivery volume is defined by the design of the cam ring. The pump shaft is installed in the housing with plain bearings.

The volume flow control limits the supplied volume flow to a fixed value and a pressure control valve in the valve pistons controls the system pressure.
