Characteristics of the unit
The OF7 serves as a mobile filtration unit and is especially suitable to fill
hydraulic units, to flush small hydraulic units e.g. when commissioning, for
offline filtration of mineral oil in hydraulic units and for recirculation with or
without simultaneous filtration.
OF7K Additional Feature
The OF7K version is a modified standard version to suck up leaking oil with
integrated protection from dry-running.
The OF7K version has the following additional features or restrictions:
- Up to 60 hours of dry-running protection for the vane pump.
Dry-running protection is enabled by the return line (thin plastic tube)
leading from the filter back to the pump. For this, before starting up the
unit, the filter cartridge has to be at least half-filled with the fluid to be
pumped.
- The maximum operating pressure is 3.5 bar.
- Suction screen and reducer from G ¾“ to G ½“.
A 100 µm strainer is screwed into the reducer to protect the pump from
coarse contaminants. Due to the reduction in cross-section, the nominal
flow rate is also reduced.
- The relay in the terminal box has floating contacts to signal "voltage
present" and "pump switched on".
The contact is normally closed.
- A signal cable 10 m or 15 m 2x0.5 mm² with 5-pin coupling (pins).
Connector: AMP T 3360 001
