How To Optimize Contact Pressure Setting; For Maximum Of Hose Life; Pump Operation With Partial Use Of A Multi - Channel Pump Head - Heidolph PD 5001 Manual De Instrucciones

Fold hose over rotor, depress latch (refer to pig. 37) until pawl snaps in (refer to fig. 38).

fig. 37
Note: as required, depress hose cassette at place marked in fig. 38, to ease snap action.
Adjust hose contact pressure. Turn knob (59) until inside edge of wedge is centered between
-
#1 and #2 marks on the data plate graduation (refer to fig. 34).

5.1.1. How to optimize contact pressure setting

For certain applications, contact pressure needs re-adjustment . For example, varying feed rate of
a particular hose, minimizing feed rate fluctuations caused by changes in system pressure, or to
simply extension.

5.1.1.1. For maximum of hose life

With the pump running, decrease hose contact pressure adjusted before. To this end turn
regulating knob (59, fig. 34) counterclockwise to displace wedges to a higher scale reading
(towards 5). Go ahead turning knob (59, fig. 34) until feed rate or pressure are too low. From this
point go ahead turning knob clockwise until feed rate and pressure are ok.
5.1.2. Pump operation with partial use of a multi-channel pump head (fig. 39)
Pump may be run with all or part of the multi-channel pump head's ports connected. Both metal
rods of the pump feature an elastic packing (60) on both ends that secures cassettes on the pump.
Secure multi-channel pump heads with part of the ports loaded with cassettes by slipping packings
(60) over the rods towards the front end of the outboard cassette (refer to e.g. position A). On
