Industrial and Commercial Water Pumps
The Grundfos CR and CRN high-pressure pump series are versatile, non-self-priming, vertical multistage centrifugal pumps designed for a range of applications, including handling potable and industrial liquids at high pressures. Key features and models include:
- CRNE 1 and 3 HS: Single pumps capable of generating up to 692 psi. These pumps feature a high-speed motor with an integrated frequency converter, and an inverted chamber stack for reversed liquid flow direction.
- CRN 5, 10, 15, and 20 SF: Double pump systems generating up to 696 psi. They consist of two pumps in series—one for feeding and the other for high-pressure applications. These systems include a TEFC motor and have a reversed chamber stack for reversed liquid flow direction.
- CR32, CRN 32: High-pressure pumps generating up to 568 psi. They are designed for high-pressure performance with a specialized shaft seal and, when needed, a pump sleeve and bearing flange for enhanced pressure handling.
- 2x CR(N) 45, 64, and 90: Double pump systems generating up to 557 psi. They feature two pumps in series—a standard pump for feeding and a high-pressure pump. These systems include a high-pressure shaft seal and, if necessary, additional components for handling higher pressures.
- 2x CR(N) 120 and 150: Similar to the above, these double pump systems also generate up to 557 psi with two pumps in series—one standard and one high-pressure. They are equipped with a high-pressure shaft seal and other components to support high-pressure applications.
