Oil service equipment for hydraulic and lubrication systems

  • Stationary Units Standard - (US Series)

  • Mobile Units Standard - (UM Series)
  • Mobile Units for fluid controlling - (UMFC Series)
  • Mobile Units - Explosion Proof - (UMP Series)

Effective oil service for hydraulic and lubrication systems requires, beside using an operating filter, the application of a filter unit for off-line filtration, oil change and filling. Before the initial start-up in production facilities and lubrication systems, as well as in mobile and stationary hydraulics, a flushing should be performed, which often isn’t the case. Unfiltered oil gets into the tank and causes sludge accumulation. In order to prevent the above mentioned contamination process, the fluid should be filled in via a fine filter of an off-line filtration unit.

An off-line filtration unit with an electric motor, improves the cleanness and quality of the operating fluid and prolongs its durability, thereby preventing early wear and tear of system components.

Off-line filtration

During off-line filtration the filter is located in a circuit which is separated from the main stream. By separating the streams, off-line filtration can be performed as long as it takes for the operating fluid to reach the wanted cleanliness class, regardless of the system’s running time.

Stationary filter units – US series

The stationary filter units - US series are meant for fine filtration, filling or flushing of hydraulic systems. Equipped with a gear pump driven by an electric motor, the US filter units are designed in different sizes, for different volume flows and with various filter elements depending on the needed filtration fineness.

The stationary filter units with plate heat exchanger - USP series are an ideal tool for maintenance and service personnel to cool and clean the hydraulic and/or the lubricating oil. Tests showed that 10 °C lower temperature is doubling the life time of the operating hydraulic oil, and preventing additional side effects of thermal degradation, seal failure, loss of film strength on the surface of the hydraulic components (like valves, cylinders etc.) which might lead to severe damages and unscheduled downtime of the systems.

Mobile filter units – UM series

The mobile filter units - UM series were as well developed for oil maintenance on hydraulic and lubrication systems, being the mobile version of the US filter series.

The main aim of the mobile oil service units for fluid controlling - UMFC series is to simplify off-line filtration and filling of reservoirs, and to monitor ISO cleanliness levels at the same time. Instead of having to replace oil prematurely, it can be filtered and used again, saving costs for oil disposal or for buying new oil – not to mention the effects on the environment. The UMFC units include a fluid control function, performed by the particle counter CCT 01-Set and the water sensor WSPS 05.

Advanced Fluid Management: Fluid Purifier Systems IFPM/IFPS

The IFPM/IFPS Fluid Purifier Systems are designed for viscosity ranges from transformer oils to heavy gear lube oils (ISO 460), able to remove free, emulsified and dissolved water, free and dissolved gases and particulate contamination down to 1μm. The fineness of the filter - ranging from very fine to coarse - is selected according to the kind of contamination. The IFPM/IFPS systems are available in four different standard sizes from 20 to 100 l/min, mobile (IFPM) or stationary (IFPS), and as explosion-proof as well.

Due to the reduction of fluid ageing, the maintenance of lubricity and the decrease of the air and water content, the equipment reliability of the whole system and the durability of the used fluids, are being significantly improved.
