Offshore containers for Hydraulic Power Units (HPU) Hydraulic equipment that is used and transported on and off ships is often housed within a container. Hydraulic power units are commonly required for Launch and Recovery Systems (LARS), Remotely Operated Vehicles (ROV) and Winches. This would be normally designed to meet Offshore or Maritime standards.

How to read hydraulic circuits Hydraulics symbols are an essential component of hydraulic circuit diagrams. Knowing some of the basic principles will help understand a wider range of symbols. Explaining the common ISO1219 symbols enables a complete hydraulic system to be followed:

HPR power packs can often need to be bleed when commissioning, despite being fully tested at the time of manufacture. This is required when the oil drains from the main manifold. Priming the hydraulic power pack is necessary as it fills the cavity between the pump outlet and the pilot check valve.

Before approaching the task of installing a hydraulic powerpack there are 5 things that you must remember not to do...1. Connect the hydraulic power pack to an existing system without cleaning or flushing it.We often see this issue in single acting systems, such as a scissor lift or tipper truck, where a hydraulic power unit is replaced but the pipework and cylinder have contaminated oil in them. When the equipment is first operated this dirt is returned into the hydraulic power pack through the...
