Product Description
CME3-5 A-R-G-V-AQQV
Compact, reliable, horizontal, multistage, end-suction centrifugal pump with axial suction port and radial discharge port. Pump materials in contact with the liquid are in high-grade stainless steel. The mechanical shaft seal is a special designed, unbalanced O-ring seal. Pipework connection is via internal Whitworth pipe threads, Rp (ISO 7/1).
The pump is fitted with a 1-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 holds terminals for these connections:
one dedicated digital input
two 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 configurable digital input or open-collector output
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.
