CMN CM/PV water-lubricated PM VSD screw — cooling variants — CMN / Xinmaien Technology (Taizhou)

Datasheet

Product overview

Power: Selected CM22PV:22 kW; table examples7.5–315 kW · Pressure: CM22PV rows:0.8 / 1.0 / 1.25 MPa · Flow: CM22PV:1.40–3.50 m³/min at0.8 MPa

CMN's CM/PV is a water-lubricated oil-free screw family with permanent-magnet variable-speed control. Its actual model table labels the flow as FAD and separates air-cooled and water-cooled installation data. The source states that the F suffix denotes air-cooled parameters. Motor rating, pressure row, cooling version and complete flow-reference conditions belong together; the page's short headline range does not replace the detailed table.

CM22PV(F) lists 22 kW and 1.40–3.50 m³/min at 0.8 MPa, 1.25–3.13 at 1.0 MPa and 1.04–2.61 at 1.25 MPa. Air-cooled size/mass are 1900 × 1000 × 1635 mm and 1023 kg; water-cooled figures are 1680 × 1000 × 1335 mm and 873 kg. The row gives a 1-inch air outlet, DN25 cooling-water connections and 5 T/h cooling water with the table's 32°C inlet reference for the applicable water-cooled arrangement. These quantities do not establish make-up-water consumption or the complete lubrication-water circuit.

Other selected 0.8 MPa rows give CM08PV(F): 7.5 kW and 0.45–1.15 m³/min; CM75PV(F): 75 kW and 5.16–12.90; CM315PV: 315 kW and 21.80–54.50. The 1.0 MPa CM315PV row gives 19.97–49.92 instead. The original CM55PV product image is a family view; its pictured markings are manufacturer presentation, not independently verified current certification of the offered model.

Specify sustained/peak use, pressure at the process connection, motor supply and load-control needs. Request pressure-matched FAD with reference conditions, package input, minimum stable speed and control interface. For water cooling, agree inlet temperature, quantity/quality, pressure and return/drain arrangement; for air cooling, agree ventilation, heat rejection and service clearance. Define moisture, oil and particle targets with downstream dryer/filter scope and sampling tests. Obtain current model-scoped air-purity evidence, installation drawings, manuals, wear parts and commissioning terms.
