EXCEL® XR METERING PUMP
Introducing the expanded functionality of the EXCEL® XR
chemical metering pump: Engineered to meet today’s most
demanding standards for accuracy, reliability, and process
control flexibility. EXCEL XR is not just another metering
pump, but one built using the latest technology for the
most demanding applications.
LMI designed the EXCEL XR series from the ground up
based on valuable feedback received from our customers
as well as treatment plant maintenance, operators, and
industry experts.
EXCEL XR Performance Chart
The EXCEL XR metering pump features a variable speed
drive allowing full control of the stroke profile for maximum
control of the chemical going into your process. In
addition, it also features a wide variety of control options
that are easily configured using the intuitive user interface.
Whatever your application, the EXCEL XR
is ready to be your go-to solution for your most demanding
applications.

Multilanguage, user-friendly navigation
EXCEL XR’s backlit color display allows for convenient navigation in five languages: English, French, Portuguese, Spanish,
and Chinese. The enhanced control version is ready for digital or analog control interface and an extensive variety of inputs
and outputs for various digital and analog devices. The EXCEL XR Communications model offers Profibus DP and Modbus
RTU communications protocols to enable communication with many devices connected to the same network. EXCEL XR
provides everything you need to assure you have complete control of your process.
Innovative Drive System
By using a variable speed drive, the EXCEL XR pump is able to achieve ± 1% steady state accuracy over 1000:1 turndown
ratio by controlling the stroke profile. As a result, the EXCEL XR provides consistent operation and greater flexibility for
handling difficult chemicals such as polymers and other viscous fluids. When the EXCEL XR is activated it is always
discharging chemical except during the brief suction stroke. There is no idle time like you see with traditional solenoid pumps
at lower capacity settings.
Traditional Solenoid Pump vs EXCEL XR
In applications where chemicals, such as peracetic acid, are sensitive to suction stroke-speed due to high
viscosity or degassing characteristics, EXCEL XR features “Slow Mode”. Slow Mode allows the user to slow
the suction stroke of the pump. This provides better high viscosity fluid handling for applications where a
quick suction stroke isn’t ideal. Engaging Slow Mode reduces the overall output capacity of the pump due to
elongating the suction stroke duration.
