Product overview CR-H, CRN-H, CRE-H, CRNE-H Introduction This data booklet deals with CR-H and CRN-H horizontal end suction pumps as well as CRE-H and CRNE-H pumps. CR-H, CRN-H There is also a full range of CR-H, CRN-H pumps with standard Grundfos connection sizes that are optimized to give greater performance and efficiency. CRE-H, CRNE-H Fig. 1 CR-H pumps CR-H, CRN-H pumps are horizontal end suction pumps typically mounted on baseplates. The end suction design enables the pump to be installed horizontally in traditional, end suction design piping where the pump has an axial suction port and a radial center line discharge port. This design allows “back pull-out” capability so that most models can be serviced without removing the volute from the pipe system. Grundfos CR-H, CRN-H pump range includes various pump sizes and various numbers of stages to provide the flow and the pressure required. CR-H, CRN-H pumps are suitable for a variety of applications from pumping of potable water to pumping of chemicals. The pumps are therefore used in a wide variety of pumping systems where the performance and material of the pump meet specific demands. The CR-H, CRN-H pumps consist of three main components: the motor, the pump unit, and the baseplate. The pump unit consists of optimized hydraulics, various flange connections, a pump head, an end suction volute, and various other parts. CR-H, CRN-H pumps are available in various material versions according to the pumped liquid. CR-H, CRN-H pumps can be selected that meet ASME B73.1 dimensional standards for suction and discharge piping as well as many of the baseplate dimensional standards.CR-H, CRN-H pumps do not fully comply with the ASME B73.1 specification. TM04 3882 Fig. 1 CRE-H pumps CRE-H, CRNE-H pumps are built on the basis of CR-H, CRN-H pumps. CRE-H, CRNE-H pumps belong to the so-called E-pump family and are referred to as E-pumps. The difference between the CR-H, CRN-H and the CRE-H, CRNE-H pump range is the motor. CRE-H, CRNE-H pumps are fitted with an E-motor with built-in frequency control. The CRE-H, CRNE-H pump has a Grundfos MLE motor. Frequency control enables continuously variable control of motor speed, which makes it possible to set the pump to operation at any duty point. The aim of continuously variable control of the motor speed is to adjust the performance to a given requirement. CRE-H, CRNE-H pumps are available with an attached pressure sensor connected to a frequency control. The pump materials are the same as those of the CR-H, CRN-H. Selecting a CRE-H, CRNE-H pump Select a CRE-H, CRNE-H pump if: • controlled operation is required, i.e. consumption fluctuates. • constant pressure is required. • communication with the pump is required. Adaptation of performance through frequencycontrolled speed control offers obvious advantages: • energy savings • in<strong>cr</strong>eased comfort • control and monitoring of the pump performance. See pages 10 - 12 for more information about E-pumps. TM04 4177 0909 4
