CR, CRE
The CRE pump is a CR pump, motor and integrated variable frequency drive. The CRE pump is a system which is able to solve application problems and save energy.
The basic CR pump range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.
The basic CR pump range is available in four different materials: cast iron, two grades of stainless steel, and all-titanium. There are eleven flow sizes, capable of producing up to almost 725 psi pressure, and with a variety of shaft seals, rubber materials and supply voltages.
Pump parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimized for their purpose and designed for specific requirements.

Grundfos Direct Sensors
rps
Relative Pressure Sensor:
RPI /RPI +T
The pressure sensor efficiently combines pressure and temperature measurement in just one sensor. Transforming the 
pressure in and temperature of the water into electrical signals, the transmitter offers very accurate measurement in almost any liquid.
Pressure Range: 25 bar
Media Temperature: -30 C to 120 C
Output (press): 4 to 20 mA
Output (press + temp): 2 x 0 to 10 V
rps
The heart of the sensor is a coated SMART sensor, which transforms the pressure and temperature of the medium into electrical signals. These signals are calibrated, conditioned and presented in analogue or digital format by means of a microprocessor. The pressure signals are temperature compensated and linearised for the influence of temperature variations.
rps
Differential Pressure Sensor:
DPI/DPI+T
Benefit from reliable differential pressure measurement with the unique direct transmitter that eliminates the need for pressure 
transmitters on both sides of the pump. The transmitter can be delivered as a combined differential pressure and temperature measurements in one.
Pressure Range: 16 bar
Media Temperature: -30 C to 120 C
Output (press): 4 to 20 mA
Output (press + temp): 2 x 0 to 10 V
The heart of the sensor is a coated SMART sensor, which transforms the differential pressure (difference in pressure between the two ports) and temperature of the medium into electrical signals. These signals are calibrated, conditioned and presented in analogue or digital format by means of a microprocessor. The pressure signals are temperature compensated and linearised for the influence of temperature variations. On how to utilize the differential pressure principle, please see DPS under Products/Standards.
Vortex Flow Sensor:
VFI
The flow transmitter successfully combines the established vortex principle with the patented Silicoat® technology. The result
is an affordable and accurate direct flow transmitter designed for reliable operation in aggressive media.
Folw Range: 0.9 m3/hr to 240 m3/hr
Media Temperature: -30 C to 120 C
Output (press): 4 to 20 mA
By combining the established vortex principle (von Karman, 1912) with the unique metal-glass coating, Silicoat® from Grundfos, an affordable, accurate and direct flow sensor for aggressive media is now available. The flow sensor is without any moving parts, which could deteriorate or commence clogging. The Vortex Street generates two series of turbulence (vortices) shedding behind a bluff body. By increasing flow the frequency of the vortices will increase and the frequency increases directly proportional to the flow in a full pipe. The Vortex Flow Sensor consists of a sensor, Vortex Tube and element. The sensor detects the pressure pulsation generated by the vortices, and converts the pulsation into an electrical output signal. The frequency of the pressure pulsation is a measurement of the velocity and in the defined flow pipe the actual flow is measured.
