General
Application or Use
Each pump is designed for operation at the conditions stated on the pump label (Fig 2). Should the need
arise to operate the pump outside of the conditions indicated on the pump label, Sundyne should be
contacted to check and confirm that the pump can be operated safely at the revised operating conditions.
Start Up Checklist
Pressurizing the Fluid Loop
Pressurize the double seal buffer loop or external
seal flush, if applicable, prior to admitting fluid into
the pump casing.
Venting
Sundyne 803Lr pumps not equipped with a Plan
13 are required to vented the seal area prior to
start up. This can be accomplished with a valve
connected to either a flush or vent (depending
on seal type).
Setting the Valves
To set the pump to the designated operating
point, start the pump with the suction valve in the
open position while throttling the discharge valve.
Control Checklist
Verifying Operating Conditions
Verify the following parameters against the
specifications on the Specification sheet:
•
Suction pressure
•
Suction temperature
•
Discharge pressure
•
Total head
•
Flow rate
•
Power consumption
•
Specific gravity
•
Viscosity
•
Net Positive Suction Head (NPSH)
The status of these conditions will significantly
alter performance of the pump if they are not in
accordance with the specification sheet.
Check with your Sundyne representative if the
operation conditions of your pump must run under
different parameters than indicated by the
specification sheet.
