Grundfos CRIE 5 – 3 x 415 V 50/60Hz Three Phase Vertical Multistage Pumps

The basic CRIE 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 50 bar of 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 optimised for their purpose and designed for specific requirements.

CRIE pumps provide a complete range of pump solutions so that all applications, industrial and domestic, can benefit from the Grundfos touch. The applications that can be covered include the following :

• Process water systems
• Washing and cleaning systems
• Seawater systems
• Pumping of acids and alkalis
• Ultrafiltration systems
• Reverse osmosis systems
• Swimming baths.

Features and benefits

• High efficiency
• Space-saving
• Reliability
• Service-friendly
• Suitable for slightly aggressive liquids
• High corrosion resistance
• Single-pump solution making high pressures possible.

Additional Information

Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via combined DIN-ANSI-JIS flanges.

The pump is fitted with a 3-phase, fan-cooled, permanent-magnet, synchronous motor. The motor efficiency is classified as IE5 in accordance with IEC 60034-30-2. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement. The operating panel on the motor terminal box features a four-inch TFT display, push-buttons and the Grundfos Eye indicator.

The display gives an intuitive and user-friendly interface to all functions. The push-buttons are used to navigate through the menu structure to access pump and performance data on site and enable setting of required setpoint as well as setting of pump to “Min.” or “Max.” operation or to “Stop”.

Communication with the pump is also possible by means of Grundfos GO Remote (accessory). The remote control enables further settings as well as reading out of a number of parameters such as “Actual value”, “Speed”, “Power input” and total “Power consumption”.

The Grundfos Eye indicator on the operating panel provides visual indication of pump status:

• “Power on”: Motor is running (rotating green indicator lights) or not running (permanently green indicator lights)
• “Warning”: Motor is still running (rotating yellow indicator lights) or has stopped (permanently yellow indicator lights)
• “Alarm”: Motor has stopped (flashing red indicator lights).
