8.3 Cleaning the pump hose
The inside of the pump hose can be easily cleaned by
rinsing the pump with clean water. If a cleaning fluid is
added to the water, check if the hose liner material is
resistant to it. Also check if the pump hose can resist
the cleaning temperature. Special cleaning balls are
also available. Contact your Bredel representative for
more details.
8.4 Changing lubricant
1. Place a tray (A) under the drain plug, which is in
the cover of the pump. Remove the drain plug
(B). Drain the lubricant from the pump housing
into the tray. Place back the drain plug and
tighten it.
2. The pump housing can be filled with lubricant
via the breather (A) on the cover. For this
purpose remove the breather cap (B) and
position a funnel (C) in the breather. Pour the
lubricant into the pump housing through the
funnel.
10 Replacing the rotor with
integral pressing shoes. Wear on the running sur-
face of the pump hose
