Versioned catalog rows
| Source field | MV 21 | MV 32 |
|---|---|---|
| Machine weight, empty (kg; printed qualifier retained) | ca. 895 | a. 3,330 |

| Batch load - ceramic media (kg; not part load) | 230 | 950 |
| Batch load - plastic media (kg; not part load) | 150 | 630 |
| Usable volume (L; not part batch load) | 130 | 530 |

Separate usable volume from part batch load
The 12/20 PDF lists MV 21 with 130 L usable volume and MV 32 with 530 L. Neither number establishes a part-only load, cycle time, production rate or approved operating fill. Review the actual part arrangement, media grade and media-to-parts occupancy with the trial owner. Ceramic-media batch loads are 230 kg and 950 kg; plastic-media batch loads are 150 kg and 630 kg. These kg entries belong to media types and must not be converted into workpiece load or transferable density. The brochure describes workpieces clamped at the bowl bottom, with mechanical or electromagnetic clamping systems requiring an actual fixture review.
Review configuration and geometry bases
The empty-weight entries are ca. 895 kg for MV 21 and a. 3,330 kg for MV 32. The printed qualifiers are retained; MV32 is written a.3,330 in this version, so no correction to a different qualifier or current weight is made. Maximum workpiece dimensions are measured diagonally and printed ca. 570 mm and ca. 950 mm. A single diagonal cannot approve the clamping interface, electromagnetic suitability, media access, local rib protection, transport loading or floor support. Lettered drawing dimensions are excluded from this tool.
Keep drive units and speed statements separate
Power requirements are 3.5 kVA for MV 21 and 13.0 kVA for MV 32. This is an apparent-power row, distinct from current-web kW at specified motor speeds. No power factor or conversion is provided. The maximum motor-speed entries are 3,000 rpm and 3,000 rpm with infinitely adjustable frequency inverter in the brochure footnote. These maxima are not validated processing setpoints. No total connected load, energy consumption, electricity cost, cycle time or finishing result is calculated.
Confirm the actual version and installed options
The PDF contains MV21, MV25 and MV32 columns only. The current website also lists MV50; this does not provide an MV50 record in the versioned brochure and no MV50 pair is generated here. Clamping configuration, pneumatic media discharge and installed automation require the actual offered drawing. Narrative references to medical or aerospace parts are not qualification or performance evidence for your part.
Keep current-web differences visible
MV 32: weight is a. 3,330 in the PDF and approx. 2,640 under current web label "Unladen weight (kg)". MV 32: ceramic is 950 in the PDF and 995 under current web label "Ceramic grinding media capacity (kg)". MV 32: plastic is 630 in the PDF and 660 under current web label "Plastic abrasive media capacity (kg)". MV 32: usable is 530 in the PDF and 555 under current web label "Max. usable volume (l)". PDF kVA and current-web kW rows have different physical bases; no conversion or numeric equivalence. PDF MV32 empty weight is printed a.3,330; preserve the atypical qualifier, do not silently correct to ca. Current web includes MV50; this PDF has no MV50 parameter record and no pair is created for it. Keep versions and physical bases separate and request the actual offered specification.

Questions about this pair
How do MV 21 and MV 32 compare in usable volume?
The 12/20 PDF lists MV 21 with 130 L usable volume and MV 32 with 530 L. Neither number establishes a part-only load, cycle time, production rate or approved operating fill. Review the actual part arrangement, media grade and media-to-parts occupancy with the trial owner. Ceramic-media batch loads are 230 kg and 950 kg; plastic-media batch loads are 150 kg and 630 kg. These kg entries belong to media types and must not be converted into workpiece load or transferable density. The brochure describes workpieces clamped at the bowl bottom, with mechanical or electromagnetic clamping systems requiring an actual fixture review.
What configuration or geometry fields need confirmation?
The empty-weight entries are ca. 895 kg for MV 21 and a. 3,330 kg for MV 32. The printed qualifiers are retained; MV32 is written a.3,330 in this version, so no correction to a different qualifier or current weight is made. Maximum workpiece dimensions are measured diagonally and printed ca. 570 mm and ca. 950 mm. A single diagonal cannot approve the clamping interface, electromagnetic suitability, media access, local rib protection, transport loading or floor support. Lettered drawing dimensions are excluded from this tool.
Can these drive rows be used as power or process settings?
Power requirements are 3.5 kVA for MV 21 and 13.0 kVA for MV 32. This is an apparent-power row, distinct from current-web kW at specified motor speeds. No power factor or conversion is provided. The maximum motor-speed entries are 3,000 rpm and 3,000 rpm with infinitely adjustable frequency inverter in the brochure footnote. These maxima are not validated processing setpoints. No total connected load, energy consumption, electricity cost, cycle time or finishing result is calculated.
Which version and availability statements must remain separate?
The PDF contains MV21, MV25 and MV32 columns only. The current website also lists MV50; this does not provide an MV50 record in the versioned brochure and no MV50 pair is generated here. Clamping configuration, pneumatic media discharge and installed automation require the actual offered drawing. Narrative references to medical or aerospace parts are not qualification or performance evidence for your part.
Does the current official website agree with the PDF?
MV 32: weight is a. 3,330 in the PDF and approx. 2,640 under current web label "Unladen weight (kg)". MV 32: ceramic is 950 in the PDF and 995 under current web label "Ceramic grinding media capacity (kg)". MV 32: plastic is 630 in the PDF and 660 under current web label "Plastic abrasive media capacity (kg)". MV 32: usable is 530 in the PDF and 555 under current web label "Max. usable volume (l)". PDF kVA and current-web kW rows have different physical bases; no conversion or numeric equivalence. PDF MV32 empty weight is printed a.3,330; preserve the atypical qualifier, do not silently correct to ca. Current web includes MV50; this PDF has no MV50 parameter record and no pair is created for it. Keep versions and physical bases separate and request the actual offered specification.
