Simplex and Multiplex Pump Control 

Variable speed, constant pressure control solutions

0.33 hp to 200 hp (0.25 kW to 132 kW)

120 V to 690 V

The Control Techniques Unidrive M400 Pumping Solutions are a cost effective and versatile variable speed control system for maintaining energy efficient, constant pressure in single-phase (0.33 - 50 hp) or 3-phase (0.5 - 200 hp) applications. These single-pump and multi-pump (up to 3 max) configurations have been improved with new documentation and utilize the onboard controller on the Control Techniques Unidrive M400 drives which make it easy to set up new systems.

Based on the highly reliable Unidrive M400 AC drive, these solutions provide programming dedicated to simplex and multiplex pump operation. The AI-CTASP (simplex pump) and AI-CTAMP (multiplex pump) come with an AI-BACKUP-ADAPTOR with SD card loaded with default pump parameters pre-loaded to make it easy to setup application parameters to the drive while the pre-programmed simplex or multiplex 

Unidrive M400 eliminates the need for an external PLC saving cost, space and engineering time.

A simple solution for simplex and multiplex pump applications.  Unidrive M400 is a compact, easy-to-use general purpose drive that delivers excellent motor control and offers great value.  With I/O expansion option (simplex pump) or Ethernet I/P network communications (standard with multiplex), Unidrive M400 allows you to do far more than you would expect from a standard open-loop drive.

Key features include:

  • Wide power range

0.33 hp to 200 hp (simplex pump)

0.5 hp to 200 hp (multiplex pump)

  • Easy to configure

The separately ordered AI-CTASP (simplex) and AI-CTAMP (multiplex) makes transferring parameters fast and easy. The Unidrive M400 onboard controller is pre-programmed with the respective pump solutions used within the drive. A new user guide provides comprehensive information for the simplex and multiplex solution.

  • SStart/Stop and control modes

Including pressure and flow switch, pressure transducer and flow switch, pressure transducer only.

  • Smooth S-ramp speed variationSmooth S-ramp speed variation

Avoids water hammer.

  • Versatile

The Unidrive M400 pump parameters can be setup from an SD card (order code AI-CTASP or AI-CTAMP) and keypad (order code CI-KEYPAD) or PC using the FREE Unidrive M Connect software.  The simplex pump requires either an optional programming cable (order code CT-USB-CABLE) and RS485 connection (order code AI-485-ADAPTOR) or SI-Ethernet to connect to a PC.  The multiplex pump solution can be connected to a PC over the SI-Ethernet module required for multiplex operation.

  • Expandable

SI-I/O option module for additional I/O (simplex pump only).

  • Communications

SI option modules for fieldbus and Ethernet connectivity for simplex pump. Multiplex pump solutions are provided with an SI-Ethernet module as standard. AI-485-ADAPTOR provides Modbus RTU communications for both simplex and multiplex pumping solutions.

  • High Performance

Open-loop vector control.

Load transfer and alternating lead pump control (multiplex pump).
