Bell & Gossett Series e-90E Smart Pumps

Series e-90E Smart Pumps are close-coupled, in-line centrifugal pumps that combine the comprehensive hydraulic coverage of the e-90 pump with the efficiency of Xylem's Smart Motor in a pre-assembled package. Each e-90E Smart Pump provides power, intelligence, and performance right out of the box.

Xylem's permanent magnet Smart Motor is highly efficient, minimizing power loss while transferring maximum energy to the hydraulic parts of the pump. The refined control system with an integrated microprocessor adjusts the motor speed, matching the required operating point of the pump or system requirements and reducing the demand for electricity according to the necessary working conditions. Built-in pump protection controls and monitoring help optimize pump operations, increasing energy savings by up to 70% (vs. fixed speed) while reducing installation time.

Series e-90E Smart Pumps are ideal for small commercial HVAC systems with various applications, including hydronic heating and cooling, pressure boosting, refrigeration, and heat exchanger circulation. They are available in bronze-fitted or all-bronze construction to meet a wide range of pump needs.

e-90E Features

Pre-Programmed Package

Series e-90E Smart Pumps feature a motor, variable speed drive, and hydraulic pump in pre-programmed packages with built-in pump protection controls and monitoring to help optimize pump performance. The pre-assembled package requires no external control panel or programmable logic controller (PLC).

High Performance, Low Energy Use

High-efficiency hydraulics, permanent magnet motor technology, and variable speed drive provide the lowest possible operating cost. The refined control system with an integrated microprocessor adjusts the motor speed to match the operating system's demand, resulting in significant energy savings while extending the equipment's life cycle.

Best-in-Class Efficiency

The ultra-premium combined with permanent magnet motor technology and efficiency rating is the top efficiency level for motors designed to operate directly online. Each e-90E Smart Pump features Xylem's IE5 Smart Motor, providing efficiency well above a standard IE3 NEMA Premium efficient asynchronous induction motor.

Ease of Installation

The e-90E's pre-assembled, pre-programmed package simplifies installation. This in-line mounted, close-coupled pump is compact and versatile. It is designed to be mounted in the piping and installed horizontally or vertically.

Robust Pump Design

The compact, close-coupled platform eliminates the need for a bearing frame or coupler. A stub shaft or shaft sleeve is not required. The modern unitized EPR/Carbon/Silicon-Carbide mechanical seal is standard, offering easy removal and long service life. The back-pull-out design allows service access without disturbing the piping.
