Hydraulic gear pump with close up detail showing ceramic heater element insulators with flat, possibly nichome, metal strip element threaded through them. This oil heating system was designed to maintain a specific viscosity of the oil regardless of environmental temperature, to better maintain oil flow rates and thus pump efficiency. The heating system is found only rarely on surviving relics.

Close-up of Askania gear pump relic with oil heaters. This picture shows an unusual feature on the otherwise normal cast aluminium base of this gear pump. The knurled knob positioned between the oil flow balance adjusters has a purpose that is unknown to us. The two oil-flow balance adjuster valves visible in the picture have slot head adjuster screws and you can also see the knurled circumference on each screw. This parallel knurling is engaged by a crease formed in the facing surface of the copper spring strips. The function of these strips is to create tactile feedback that the technician making the adjustment can feel in the handle of the screwdriver. This was done because the gear pump needed to be adjusted in a dark and narrowly confined space.
Gear pump showing flow adjusters (two slot head screws nearest bottom of picture) and ceramic heater elements situated at each end of the block. The square drive shaft coupler (corroded but still identifiable) has been highlighted in red paint. The open holes either side are the main control valve guides. The copper spring strips visible on each oil flow adjuster provide locking and tactile feed-back for the adjusting process. This relic was recovered from Usedom island.
