Close
A vertical multi - stage centrifugal pump integrated with a frequency converter. The pump head and base are made of cast iron, and all other wetted components are made of stainless steel (EN 1.4301).
CRE Vertical Multistage Centrifugal Pump: Variable - Frequency Control The CRE is a multi - purpose vertical multistage centrifugal pump, manufactured from AISI 304 - grade stainless steel / cast iron. It is equipped with a built - in frequency converter, enabling it to adapt to various flow rate and pressure requirements. The variable - frequency drive can continuously adjust the pump's performance to meet the requirements of current, pressure, temperature, or flow rate. This makes the CRE highly suitable for a wide range of applications, including water supply, washing and cleaning, water treatment, boiler feedwater, chemical industry, temperature control, and mining. |

CRE 95 - 1 - 1 V - F - A - E - HQQE Vertical multistage centrifugal pump with the inlet and outlet on the same horizontal plane (inline). The pump head and base are made of cast iron, while all other components in contact with the liquid are made of stainless steel. The Grundfos cartridge shaft seal improves the reliability of the machine and the safety of operation, and simplifies maintenance. Electrical energy is transmitted through a split - type coupling. Pipe connections are made via DIN flanges. An asynchronous motor with three phases, a cooling fan and feet is installed on the pump. According to the IEC 60034 - 30 - 2 standard, the energy efficiency of this motor is at the IE5 level. The motor terminal box contains a frequency converter and a PI controller. This enables the system to continuously adjust the motor speed, allowing the pump to be optimized for operating conditions.
