NBGE 2-Pole : Close-Coupled End-Suction Pumps (Iso 2858) 50/32/160 to 50/32/200
Product Description
NBGE 50-32-160/139 ACAE2CESBQQEIWB
Non-self priming, single-stage centrifugal pump according to AS2129 table E.
The pump is for the pumping of thin, clean or slightly contaminated liquids without abrasive or long-fibred solids.
The impeller is hydraulically as well as dynamically balanced.
The pump has the following characteristics:
|
The pump is fitted with an IEC-flanged three-phase MGE motor with frequency converter and PI-controller integrated in the motor terminal box. No additional motor protection is required, as both motor and electronics are protected by integrated overload and temperature protection.
An external sensor can be connected if controlled pump operation based on for example flow, differential pressure or temperature is required.
A control panel enables setting of required setpoint as well as setting of pump to MIN or MAX operation or to STOP. The control panel has indicator lights for "Operation" and "Fault".
Communication with the pump is possible by means of Grundfos R100 Remote Control enabling 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 the connection of:
