Single Acting Pump Operation Notes

E 2020 Nordson Corporation
1. The maximum number of products per minute that can be glued depends
on:
-
The amount of time required to apply adhesive per product
-
The pump's recharge time
2. Pump recharge time depends on:
-
The amount of adhesive dispensed per pump cycle
-
The adhesive viscosity
-
The air pressure supplied to the pump
3. For a full stroke (2.2 cu. in., 36 cc), expect between 750 milliseconds
and 1 second to recharge. Less than a full stroke will take less time.
4. To ensure full pressure is available at the applicators, trigger the pump
about 1 second before triggering the applicators.
5. The pump must be cycled to pressurize the system after pressure is
relieved, for example, shutting off the melter, or the pump, or triggering an
applicator without triggering the pump.
6. System pressure will gradually decrease when the pump is not cycling
frequently. Cycle the pump to pressurize the system if it has been idle for
more than 5 minutes.
