Grundfos Multistage Pump CRE 15-4 5.5 kW

CRE 15-4 A-F-A-E-HQQE

Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). The pump head and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via DIN flanges. The pump is fitted with a 3-phase, fan-cooled, permanent-magnet, synchronous motor. The motor efficiency is classified as IE5 in accordance with IEC 60034-30-2. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement. An operating panel on the motor terminal box enables setting of required setpoint as well as setting of pump to “Min.” or “Max.” operation or to “Stop”. The Grundfos Eye indicator on the operating panel provides visual indication of pump status:
• “Power on”: Motor is running (rotating green indicator lights) or not running (permanently green indicator lights)
• “Warning”: Motor is still running (rotating yellow indicator lights) or has stopped (permanently yellow indicator lights)
• “Alarm”: Motor has stopped (flashing red indicator lights).

Communication with the pump is possible by means of Grundfos GO Remote (accessory). The remote control enables further settings as well as reading out of a number of parameters such as “Actual value”, “Speed”, “Power input” and total “Power consumption”. The terminal box has a number of inputs and outputs enabling the motor to be used in advanced applications where many inputs and outputs are required:
• two dedicated digital inputs
• three analog inputs, 0(4)-20 mA, 0-5 V, 0-10 V, 0.5-3.5 V
• 5 V voltage supply to potentiometer and sensor
• one analog output, 0-10 V, 0(4)-20 mA
• two configurable digital inputs or open-collector outputs
• two Pt100/Pt1000 inputs
• LiqTec, dry-running protection sensor input
• Grundfos Digital Sensor input and output
• 24 V voltage supply for sensors
• two signal-relay outputs (potential-free contacts)
• GENIbus connection
• interface for Grundfos CIM fieldbus module.
