Grundfos 99206051 Diaphragm metering pumps with external asynchronous motor DMX 280-8 B-PVC/V/C-X-G1U3U3XEMAG
Product no: 99206051
EAN number: 5712608671364
The pump from the DMX series is a versatile diaphragm metering pump designed as a positive displacement pump. The diaphragm is mechanically connected to the highly efficient AC motor via a high-precision eccentric tappet gear. The dosing quantity is adjusted by changing the stroke length, which can be set at a ratio of 1:10 on the stroke length adjustment knob. Only applies to pumps with ATEX approval: The dosing pump DMX 226 is approved for operation in potentially explosive atmospheres in accordance with ATEX Directive 94/9/EC. The requirements for non-electrical equipment apply to the pumps themselves. The EEx-e and EEx-d motors are certified by the manufacturer (Grundfos/Alldos) in accordance with the ATEX directives that apply to electrical equipment. The information on the motor nameplate complies with the ATEX standards.
