Product details
The family uses a single-helix rotor working inside a double-helix stator. The resulting enclosed cavities move along the pumping element, providing continuous displacement with comparatively low agitation. Material and stator selection still depend on fluid chemistry, temperature and the amount and size of any solids.
The model designation separates nominal rotor size from stage count. The G35-2 row is retained here as one defined speed and pressure selection; other sizes and speed rows in the family are not combined into its ratings. Confirm the actual flow-pressure characteristic for the requested liquid.
The manufacturer warns against dry running because the stator requires protection, and its instructions call for checking the specified rotation direction. It also recommends cleaning after handling viscous, corrosive or solids-bearing media. The cleaning liquid and procedure must be compatible with both the process material and the selected stator.
