CRN Stainless Steel Vertical Multi-stage Centrifugal Pump: Strong Corrosion Resistance
CRN Stainless Steel Vertical Multi-stage Centrifugal Pump: Strong Corrosion Resistance The CRN stainless steel vertical multi-stage centrifugal pump is a pipeline-type multi-stage pump, allowing for the selection of different flow rates and pressures according to requirements. Made of high-grade AISI 316 stainless steel, it is highly suitable for applications such as ultrafiltration, reverse osmosis, machine tools (cooling lubricants), distillation systems, swimming pools, handling of oils, alcohols, acids and alkalis, process water systems, and dealing with various complex liquids in processing. Grundfos also offers a variety of CRN stainless steel vertical multi-stage centrifugal water pumps approved by ATEX. These pumps can be selected based on different locations, degrees of hazard, and potential hazardous situations. The ATEX-approved pumps are suitable for potentially explosive environments, which are typically composed of air and flammable substances (such as gases, vapors, mists, or dusts), and may trigger an explosion that spreads after ignition. |
| CRN 255-6-2 A-P-A-V-HQQV Vertical multi-stage centrifugal pump. The inlet and outlet are on the same horizontal plane (in-line). The pump body materials in contact with the liquid are high - grade stainless steel. The built - in thrust control device can absorb hydraulic axial forces, so standard motors can be used. The Grundfos cartridge shaft seal improves the reliability of the machine and the safety of operation, making maintenance easier. Electric energy is transmitted through a split - type coupling. The connection of pipelines is realized via PJE couplings. An asynchronous motor with a 3 - phase, cooling fan and feet is installed on the water pump. | |
