Workshop Technical Tip: Due to its 3-section design, this pump requires particular attention to oil quality. The suction port feeds all sections simultaneously, so any leak in the intake (air ingestion) can lead to cavitation and rapid destruction of the entire unit. During installation, ensure that the pressure ports are connected according to the diagram – the gear section (pilot) is responsible for control, while the piston sections provide the working power. Remember to prime the pump housing with oil before the first start!
