Simplex and Multiplex Pump Control

0.33 hp – 200 hp (0.25 kW – 132 kW) Simplex Pump
0.5 hp – 200 hp (0.37 kW – 132 kW) Multiplex Pump

115 V | 208 - 240 V | 380 - 480 V | 575 V | 690 V

The Control Techniques Unidrive M400 Pumping Solutions are a cost effective and versatile variable speed control system for maintaining energy efficient, constant water 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 utilize the onboard controller on the Unidrive M400 variable frequency AC drive (VFD) for economical and easy to use control.

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) options include an AI-BACKUP-ADAPTOR with SD memory card pre-loaded with default pump parameters to make application setup easy.

Additionally, an optional HMI (human machine interface) is available that makes setup and diagnostics easy and provides additional features such as remote web access and email alerts.
 
 

The Control Techniques’ Unidrive M400 Simplex Pump solution is an effective and versatile variable speed control system for maintaining constant pressure in a single pump configuration for ratings up to 200 hp. Based on the highly reliable Unidrive M400 AC drive, this product offers cost effective pump control. An embedded controller in the drive eliminates the need for an external controller saving cost, space and programming time.

How to order

1.Order any Unidrive M400 part number and replace the last 5 digits of the order code with K0033 or K0035. This includes the preprogrammed Unidrive M400 with pump software and default pump configuration drive parameters, for example:

Standard Drive: M400-02400013A10101AB100 (with DB transistor) M400-09402000E10101AN100 (without DB transistor)

Multiplex Pump Drive: M400-02400013A10101K0033 (with DB transistor) M400-09402000E10101K0035 (without DB transistor)

2. Order CI-KEYPAD-LCD for access to drive parameters, status and diagnostics and to load SD card pump files from the AI-BACKUP-ADAPTOR. One keypad is recommended to be order at a minimum.

3. Order AI-CTAMP for pump configuration drive parameters for drives one, two and three. This includes an AI-BACKUP-ADAPTOR and SD card with default pump configuration drive parameters pre-loaded.
