Duplex Pump Controllers

Duplex, Triplex, and Quadruplex controllers for constant & variable speed pumps

DCC controllers are designed to withstand the harsh conditions found in Water and Wastewater application environments. They have been used and trusted by individuals and municipalities for over three decades. DCC controllers offer a low cost, reliable, and easy to use solution to many applications.

Controllers include:

• Float Switch Pump Controllers (Constant Speed Pump Control)
• Backup Float Switch Pump Controllers (Constant Speed Pump Control)
• Digital Series II Pump Controller (Constant Speed Pump Control – Multiple Sensor Inputs)
• Universal Pump Controller (Constant and Variable Speed Pump Control – Multiple Sensor Inputs – Expanded I/O Capability)

Float Switch Pump Controllers

The DCC Float Switch Pump Controllers are designed to work with float switches to automatically detect liquid levels and control single speed pumps for lift stations and other fluid pump-down applications.

Features include:

• Two models available to control up to 3 pumps with built-in alternation and time delay between pump starts.
• Accepts up to 5 float switches.
• Pumps, floats, seal failure, temperature failure, low alarm, high alarm, high alarm light, and alarm horn status indicators on front panel.
• alarm realy output to detect alarms from remote site.
• pumps disable inputs.
• alarm horn silence inputs.
• RS-232 serial communications port for SCADA support abd pc interfacing.
• Uses non-volatile memory allowing system to retain program software during power loss.

Backup Float Switch Pump Controllers

The Backup Float Switch Controllers are designed to work with float switches to automatically detect liquid levels and control single speed pumps for lift stations and other fluid pump-down applications in the event of a primary controller failure.These units can also be used as primary controllers. When operating as a backup controller, they will only control the pumps if the primary controller fails to maintain a liquid level within the normal operating limits.

Features include:

• Fully redundant backup pump control capability to protect against primary control or sensor failure
• Two models available to control up to 3 pumps with built-in alternation and time delay between pump starts.
• 3 modes of operation including:
  • Backup single float
  • Backup duat float
  • primary float switch controller
• pumps, system, and alarams status indicators on front panel.
• Alarm relay output to detect alarms from remote site.
• Uses non-volatile memory allowing system to retain program software during power loss.

Digital Series II Pump Controller

The Digital Series II Pump Controllers are designed to work with 4-20 mA level transmitters, backup float switches, and bubbler measurement systems to automatically detect liquid levels and control single speed pumps for lift stations and other applications. Some models also include built-in bubbler level measurement system control capability. These models can be ordered with an optional bubbler system.

Features include:

• Five models available to control up to 4 pumps with built-in alternation and time delay between pump starts.
• Accepts 2 types of sensors including any 4-20 mA level transmitter and float switches.
• Built-in bubbler level measurement system control capability available in some models.
• Automatically selects a backup sensor in the event the primary sensor fails.
• Alarm relay output to detect alarms from remote site.
• Pumps disable inputs.
• Setpoints adujustable from front panel or remotely via serial port.
• Bargraph displays level, setpoints, air tank pressure, and air flow rate through the bubbler line.
• pumps, sensors, and alarams status indicators on front panel.
• Front panel test knob for simulated level input testing.
• 4-20 mA signal output proportional to level.
• RS-232 serial port for SCADA communications support and PC interfacing.
• Uses non-volatile memory allowing system to retains program software and setpoints during power loss.

Universal Pump Controller

The Universal Pump Controller is designed to work with 4-20 mA level transmitters, backup float switches, and bubbler measurement systems to automatically detect liquid levels to control any combination of single speed or variable speed pumps for lift stations and other applications. This unit can be ordered with an optional bubbler level measurement system (Model No. 12090) that is mounted on a separate flat plate. The bubbler system is fuse protected and it also provides power to the UPC controller.

Features include:

• control up to 4 pumps with built-in alternation and time delay between pump starts.
• Controls varialble and single speed pumps.
• Minimum speed adjustment.
• Expanded I/O capability.
• Isolated inputs and outputs(optional).
• Accepts 2 types of sensors including external level and pressure sensors and float switches.
• Automatically selects a backup sensor in the event the primary sensor fails.
• Connection for bettry backup with built-in charger.
• Setpoints adujustable from front panel or remotely via serial port.
• LED numeric and dual bargraph readout.
• pumps, sensors, and alarams status indicators on front panel.
• Front panel test knob for simulated level input testing.
• RS-232 serial port for SCADA communications support and PC interfacing.
• Uses non-volatile memory allowing system to retains program software and setpoints during power loss.
