High flow
A large mining company needed several pumps to
transfer sludge with flow rates up to 299 GPM. The
unique duplex hose pump was the solution for this
application. This unit has two pump heads mounted
on a single drive. With the pump shoes positioned at
90 degree intervals, the pump is capable of producing
higher flow rates than a single pump, but with much
smaller power and space requirements than two pumps.
How to use the curves
1. Flow required indicates pump speed
2. Calculated discharge pressure
3. Net motor power required
4. Product temperature
5. Calculated discharge pressure
6. Maximum recommended pump speed
Note: The area of continuous operation
diminishes with increased product
temperatures. For product temperatures
>104F, the area of continuous operation
reduces to the corresponding red
temperature line.
