3500XD
Manufacturer: ITT Goulds
Goulds 3500XD Medium Consistency Pumping Technology. Medium Consistency Pump Systems.
• Complete system of pump, valves, standpipe and controls
• Pulp consistency to 16% bone dry.
• Capacity to 2200 tons per day
• Direct drive design
• Patented air separation system
• All stainless steel construction
• Improved efficiency
• X Ducer Performance Advantage:
• Improved Pumping Efficiencies
• An increase of up to 8 efficiency points
• Performance which exceeds or rivals all competitors
• Expanded Coverage
• Higher TDH generation for existing sizes
• New, larger size to handle production rates to 2200 ADStpd (2000 ADMtpd) and heads to 650 feet (198 m)
• Dramatic Degas System Improvements
• Allows for operation up to 10 11% consistency without a vacuum pump
• Lower Suction Head Requirements
• Allows for lower standpipe elevations and higher operating temperatures
• Existing Units Readily Converted to the X Ducer Design
• Standpipe Arrangement: Stock from washers and thickeners fall into special Goulds standpipes that are reverse tapered to prevent stock bridging. Systems include controls for vacuum, dilution, level and flow.
• 3500 Tower Bottom Arrangement: Stock from bleach / storage towers falls into Goulds feed chute connected to the tower with expansion joint and isolation valve. Depending on tower level and consistency, a vacuum pump may not be required
.• Booster Arrangement: Taking stock from standard medium consistency systems, Goulds booster pumps will increase pressures but do not require standpipes or degassing systems as air was removed in the primary pump
.• Standpipe Level/ Dilution System:
Constant standpipe level maintained by LC controlling LCV on pump discharge.
Alarms set at 85% and 10% level.
Start up Interlock at minimum of 10% level to prevent dry running of pump.
Automatic dilution system to assist pumping when standpipe level exceeds its setpoint.
• Seal & Flush Water System
• Three separate flow meters control flow to:
Mechanical seal & bearing cooling coil
Vacuum pump make up
Vacuum chamber
An Alarm sounds if the flow rate drops below 50% of the required value.
An Interlock keeps the pump from starting up without minimum seal and flush water flow.
• Degas System:
Vacuum pump operates when Model 3500 operates.
ARV is open when LCV is open.
An Alarm will sound if the vacuum pump shuts down.
Closing ARV can isolate air removal system.
• Air Removal System: Without effective air removal, medium consistency pumps will not perate reliably.
• Pulp consistency to 16% bone dry.
