Description

The Grundfos CR1‑4 A‑A‑A‑E‑HQQE water pump is a precision-engineered, vertical multistage centrifugal unit designed to deliver efficient and reliable water management with a flow capacity of 2.2 m³/h and a maximum head of 36.3 m (nominal head rating at 28.2 m). Ideal for applications requiring high-pressure, low-flow operation, this pump is perfect for boosting water pressure, filtration systems, booster circuits, and light industrial processes.

Built to Grundfos’s exacting specifications, the CR1‑4 is crafted from premium-grade stainless steel, ensuring exceptional resistance to corrosion and long service life. Its vertically configured multistage impeller assembly supports low-vibration operation and compact installation, with each stage progressively increasing pressure while maintaining system stability and noise reduction. The pump’s motor and hydraulics are precisely balanced, offering smooth and energy-efficient performance across its operating envelope.

With its compact footprint, the CR1‑4 fits seamlessly into tight mechanical rooms, household systems, or industrial skids without compromising on hydraulic capability. Standardized connections and a flange-ready design simplify installation and integration with filtration, reverse-osmosis, or pressure-control units. Its vertical orientation also conserves floor space and allows for efficient inline maintenance.

Maintenance efficiency is a standout feature: the CR1‑4’s modular design enables fast access to the seal chamber and rotor assembly without the need to remove piping or motor, reducing repair time and service costs. Its high-quality mechanical seal and durable bearings contribute to long maintenance intervals and stable operation under continuous-duty conditions.

Whether deployed in domestic water boosting, commercial HVAC systems, reverse-osmosis stations, or industrial water circuits, the Grundfos CR1‑4 A‑A‑A‑E‑HQQE water pump offers a trustworthy blend of compact design, hydraulic refinement, and energy-efficient performance—making it a dependable choice for engineers and technicians seeking reliable high-pressure water delivery with minimal footprint.
