The CR, CRN high pressure series is a multipurpose high pressure water pump range suitable for a variety of different applications demanding positive displacement with reliable and cost-efficient supply. CR, CRN handles a variety of liquids from potable water to industrial liquids within a very wide temperature, flow and pressure scale.
CRNE 1 and 3 HS - CRNE-HS is a single pump solution capable of generating up to 692 psi. The CRNE-HS pump is a non selfpriming, vertical multistage centrifugal pump fitted with a high speed Grundfos motor with integrated frequency converter, type MLE. The direction of rotation is the opposite of that of standard pumps, and the chamber stack is turned upside-down, resulting in the pumped liquid flowing in the opposite direction.
CRN 5, 10, 15, and 20 SF - CRN-SF is a double pump system capable of generating up to 696 psi. The system consists of two pumps in series. The first pump is a standard pump for feeding. The second pump is especially designed for high pressures. This data booklet covers technical information about the high pressure pump. The CRN-SF pump is a non-selfpriming, vertical multistage centrifugal pump fitted with a Grundfos specified TEFC-motor. The pump consists of a base and a pump head. The pump body and the outer sleeve are secured between the base and the pump head by means of staybolts. The direction of rotation is the opposite of that of standard pumps, and the chamber stack is turned upside-down, resulting in the pumped liquid flowing in the opposite direction.
CR32, CRN 32 - CR, CRN is a pump capable of generating up to 568 psi. The pump is especially designed for high pressures. This product guide covers technical information about the high pressure pump. The CR, CRN high pressure pump is a non-selfpriming, vertical multistage centrifugal pump fitted with a Grundfos specified motor and a specially developed high-pressure shaft seal. When necessary it includes a special pump sleeve and a bearing flange which make the pump capable of handling higher pressures.
2xCR(N) 45, 64, and 90 - 2 x CR, CRN is a double pump system capable of generating up to 557 psi. The system consists of two pumps in series. The first pump is a standard pump for feeding. The second pump is can be a specially designed pump for high pressures. This product guide covers technical information about the high pressure pump. The CR, CRN high pressure pump is a non-selfpriming, vertical multistage centrifugal pump fitted with a Grundfos specified motor and a specially developed high-pressure shaft seal. When necessary it includes a special pump sleeve and a bearing flange which make the pump capable of handling higher pressures.
2x CR(N) 120 and 150 - 2 x CR, CRN is a double pump system capable of generating up to 557 psi. The system consists of two pumps in series. The first pump is a standard pump for feeding. The second pump is specially designed for high pressures. This product guide covers technical information about the high pressure pump. The CR, CRN high pressure pump is a non-selfpriming, vertical multistage centrifugal pump fitted with a Grundfos specified motor and a specially developed high-pressure shaft seal. When necessary it includes a special pump sleeve and a bearing flange which make the pump capable of handling higher pressures.
