MTRE, SPKE, CRKE pumps
Fig. 20 MTRE pumps
MTRE, SPKE and CRKE pumps are vertical multistage
centrifugal pumps designed to be mounted on top of
tanks with the chamber stack immersed in the pumped
liquid.
The pumps are available in various sizes and with
various numbers of stages to provide the flow and
the pressure required.
The pumps consist of two main components:
The motor and the pump.
• The motor is a standard Grundfos MLE motor with
integrated variable frequency drive.
• The pump has optimized hydraulics as well as
various types of connections, chambers, a motor
stool, and various other parts.
MTRE, SPKE and CRKE pumps can be connected to
an external sensor enabling the control of pressure,
differential pressure, temperature, differential
temperature, flow, or level control of liquid in a tank.
Applications of MTRE, SPKE, CRKE
The pumps are used in a wide variety of pumping
systems where the performance and materials of the
pump are required to meet specific demands.
Below is a list representing some general examples of
applications:
• spark machine tools
• grinding machines
• machining centers
• cooling units

Fig. 21 CME pump
CME pumps are reliable, quiet and compact horizontal
end-suction pumps. The modular pump design makes
it easy to make customized solutions. The CME pumps
are available in cast iron and stainless steel.
The pumps are available in a large number of sizes
and stages to provide the flow and pressure required.
The pumps consist of two main components:
The motor and the pump.
• The motor is a standard Grundfos MLE motor with
integrated variable frequency drive.
• The pump is available in three material variants:
cast iron, AISI 304 stainless steel, and AISI 316
stainless steel. It has optimized hydraulics and is
available with various connections, for example
DIN/JIS/ANSI flanges.
CME pumps can be connected to an external sensor
enabling the control of pressure, differential pressure,
temperature, differential temperature, flow, or level
control of liquid in a tank.
Applications of CME
The pumps are used in a wide variety of pumping
systems where the performance of the pump is
required to meet specific demands.
Below is a list representing some general examples of
applications:
• pressure boosting
• water supply
• water treatment
• industrial washing and cleaning
• heating and cooling in industrial processes
• fertilizer systems
• dosing systems.
